…are there any messages in messages, syslog or daemon (/var/log/*) ?
-
Nothing special.
The only thing I noticed in /var/log/mail.log is
Sep 10 09:50:49 kopano kopano-dagent[207613]: Unable to commit message: disk error (80040116) Sep 10 09:50:49 kopano kopano-dagent[207613]: Unable to deliver message to "alex": disk error (80040116) Sep 10 09:50:49 kopano kopano-dagent[207613]: Unable to deliver all messages for server "default:"Don’t know what this is? I just set dagent log to 5, to get more info about this.
The weird thing is, that everything worked for two days without any problems. And then after I restarted the server because I moved it to its designated place on my floor, it began again. Everytime I restart der server service it immediately begins flooding the memory:
Crazy… :-(
-
I found out about the disk error message. There was one corrupted message in the postfix queue.
A “postqueue -f” and the error showed up again in the log.
After deleting the message from the postfix queue the kopano-dagent error vanished. -
The problem still exists. I don’t see anything weird or any errors in the logs.
Here is the output of kopano-stats --system:

Shutting down the search process ends the high CPU usage. But the memory usage keeps rising.Does anybody have a hint for me? What could I check or do to get the system running without restarting every 5 hours.
Thanks,
Alex

hi, can you post an output of :
dpkg -l | grep kopano apt-cache policy kopano-serverand did you upgrade this version from a 8.5?
then read : https://forum.kopano.io/topic/1305/crash-kopano-core-upgrade-from-8-5-81-288-0-53-1-to-8-6-80-645-0-68-1/18
after cleaning up the left overs, im out of problems. -

P.S.: Actually there is always a high CPU usage of kopano-search, kopano-server and mysqld:

Unfortunately not. kopano-server still crashing every 4 - 5 hours after flooding the whole RAM and SWAP memory. :-(

hello @Sniks6,
i had a similar issue on a testsystem, resolving was quite questionable :)
first i made the mariadb tuning for the system, second i reduce the index-process to 1 worker for first indexing.
then i only started search, wait 5 minutes till it complains about missing kopano-server, then start it, without gateway or dagent.
Wait for the first indexing, this worked fine in my case but used a lot of time.If this works, stop everything, incrase the indexing worker to standard value (i think it was 5) and start everything.
The stats of this vm where:
VMware machine
4 cores
8GB ram
scsi sas drives
CentOS 7 64bit
mariadb - 5.5.60-1
kopano-server - 8.6.4.0
no webapp, since its an external machineregards,

Its does not really make sense, that the growth in ram usage stopped, after a mysqldump was performed.
depending on tuning it could take a while until the initial search index has been completed. does the growth im ram usage also occur if you stop kopano-search?
8.7 has the possibility to perform tuning in kopano-server on its own. maybe it configures to high values for you? what happens if you manually set the options for the caches in server.cfg?

Hi @ all,
Thank you very much for your anwers!
Its does not really make sense, that the growth in ram usage stopped, after a mysqldump was performed.
That’s true. Perhaps I just didn’t start all services at the time I made the mysqldump.
depending on tuning it could take a while until the initial search index has been completed. does the growth im ram usage also occur if you stop kopano-search?
You’re right. The search service always uses much cpu und I think after two weeks it still hasn’t finished the indexing. :-(
I stopped kopano-search 2 hours ago and at the moment the cpu and memory usage is very low:top - 15:24:59 up 6 days, 4 min, 3 users, load average: 0,03, 0,06, 0,01 Tasks: 123 total, 1 running, 122 sleeping, 0 stopped, 0 zombie %Cpu(s): 0,2 us, 0,3 sy, 0,0 ni, 99,5 id, 0,0 wa, 0,0 hi, 0,0 si, 0,0 st KiB Mem : 8045376 total, 5219748 free, 564032 used, 2261596 buff/cache KiB Swap: 4143100 total, 4040092 free, 103008 used. 7173136 avail Mem PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 158017 mysql 20 0 726648 243176 17020 S 0,0 3,0 1:32.18 mysqld 161987 kopano 20 0 360232 71796 18200 S 0,0 0,9 0:12.51 kopano-server 165057 www-data 20 0 734928 43668 35932 S 0,0 0,5 0:00.76 apache2 163614 www-data 20 0 740548 43224 33404 S 0,0 0,5 0:00.92 apache2 108383 www-data 20 0 740392 43132 33628 S 0,3 0,5 0:02.50 apache2 164767 www-data 20 0 735112 42924 34632 S 0,0 0,5 0:00.82 apache2 168432 www-data 20 0 735064 42452 34652 S 0,0 0,5 0:00.52 apache2 164391 www-data 20 0 739752 42276 33036 S 0,0 0,5 0:00.64 apache2 165992 www-data 20 0 735012 40456 33280 S 0,0 0,5 0:00.50 apache2 168150 www-data 20 0 734292 40408 33536 S 0,0 0,5 0:00.36 apache2 103010 www-data 20 0 734872 40388 32832 S 0,0 0,5 0:02.11 apache2 164770 www-data 20 0 734660 40136 33020 S 0,0 0,5 0:00.64 apache2 165990 www-data 20 0 734628 38988 32424 S 0,0 0,5 0:00.44 apache2 170618 www-data 20 0 666752 33664 28192 S 0,0 0,4 0:00.02 apache2 170622 www-data 20 0 666752 33664 28192 S 0,0 0,4 0:00.02 apache2 162160 kopano 20 0 230108 20472 18368 S 0,0 0,3 0:00.24 kopano-spooler 162138 kopano 20 0 160660 16596 14668 S 0,0 0,2 0:00.08 kopano-dagent 247 root 20 0 70680 9724 9492 S 0,0 0,1 1:38.56 systemd-journal 146108 root 20 0 101436 6904 5900 S 0,0 0,1 0:00.22 sshd 170192 root 20 0 101432 6856 5852 S 0,0 0,1 0:00.22 sshd8.7 has the possibility to perform tuning in kopano-server on its own. maybe it configures to high values for you? what happens if you manually set the options for the caches in server.cfg?
I already changed the cache to:
cache_cell_size = 2GUnfortunately without success.
As of now with the disabled kopano-search it looks good. Is there a way to find out what causes this mem flooding when indexing by kopano-search?

Good Morning everyone,
now, after 17 hours it looks good kopano-server did not crash since then.
So I think we found the problem: kopano-search is causing the memory flood in kopano-server.But why? As Coffee_is_life wrote on his setup after completing the index process everything worked fine. Perhaps this is the same with my setup. But my indexing is running for two weeks now. :-(
Do you have any ideas what to tweek in this case?
-
After 4 days without kopano-search kopano-server did not crash anymore.
But the memory keeps still rising much more slowly…
Any thoughts?
-
I also (still?) have this problem. Currently using 8.6.81.171-0+25.1 on Ubuntu 18.04 x64.
[Fri Sep 28 19:51:29 2018] Out of memory: Kill process 1240 (kopano-server) score 902 or sacrifice child
[Fri Sep 28 19:51:29 2018] Killed process 1240 (kopano-server) total-vm:26514968kB, anon-rss:10946196kB, file-rss:0kB, shmem-rss:0kBBy the time it had crashed it was running only for 11 hours or so - after having been restarted due to a kopano-server crash the day before. The server should have enough memory for normal use (12GB) and an additional 16GB Swap is available. Especially with the swap I really see no reason at all for it to run out of memory.
I will now try to update to 8.6.81.435-0+75.1 in the hope that this out of memory bug has been fixed in the meantime?
In addition I’ve also cleaned the /var/lib/kopano/search/ directory and restarted the indexing process. Maybe index is corrupted?
Update: Has not changed/fixed anything. Server still crashing about once a day. Redoing the index didn’t help, neither did disabling the indexing of attachments.
I’ve added the following to the kopano-server.service file for a temporary fix:
[add in the service section]
Restart=on-failure
RestartSec=10s[add in the unit section]
StartLimitIntervalSec=300s
StartLimitBurst=2 -
Thank you for your message.
Here is a graph of the memory consumption:
- In the first half you see the memory rising very quickly till the server process crashed. It restarted automatically after modfying the kopano-server.service file.
- In the second half (~ week 38) I didn’t start the kopano-search process. The memory is still rising but much slower.
So I think it is not a problem with the search process. It seems that the search process simply speeds up the rising of the memory usage. If I had more users or much more interaction with the server process, perhaps the memory would be rising faster again.
So it looks like a problem in the kopano-server.
Just for interest, what hardware do you use, Gerald? Is it virtualised hardware? If yes which kind (VMware, HyperV,…)?

Alex

I’m using VMware ESXi (Free Edition), currently version 6.5.0 U1 (Build 7967591). The VM has the open-vm-tools package installed.
I don’t think the behavior would change on physical hardware though.Update: crashed again:
[Tue Oct 2 12:01:22 2018] Out of memory: Kill process 2038 (kopano-server) score 848 or sacrifice child
but my modifications to automatically restart the process worked so I guess nobody even noticed.Just 6 hours later memory usage for the kopano-server process was again up to 5.6GB, after restarting kopano-server memory usage is down to 350MB. This thing is leaking like crazy! At this rate even throwing 32GB at it would not really help for long.
Update2: regarding kopano on physical hardware
I just checked the kopano I’m using for my personal email, which is on physical hardware (Atom-based Quadcore NUC with 8GB RAM) and here kopano-server is hogging about 3GB of memory after running for 48 hours under low load (about 3 users with 3 devices each). Also an Ubuntu 18.04 system by the way. -
@Gerald: Thanks for your infos. :-)
Isn’t there anybody who could give us a hint, where we could tweak or check what could cause this memory problem?

This does not look like there is something to tweak, but this rather is a memory leak somewhere in the master branch. We want to branch of a release soon, so we eventually will need to look into it.
I’ve created https://jira.kopano.io/browse/KC-1299 to track progress.

Thanks for your message, Felix.
If it is helpful, I could provide you more info from my system.I am happy to help.
