…stupid question. Is your harddisk full? What kind of disk/partitions layout do you use (sizes)?
…next. Did you tune you’re mysql/mariadb (Kopano server.cfg)? There are so many sql-requests -
no harddisk isn’t full:
root@kopano:~# df -h Dateisystem Größe Benutzt Verf. Verw% Eingehängt auf udev 3,9G 0 3,9G 0% /dev tmpfs 786M 81M 706M 11% /run /dev/sda2 114G 95G 14G 88% / tmpfs 3,9G 52K 3,9G 1% /dev/shm tmpfs 5,0M 0 5,0M 0% /run/lock tmpfs 3,9G 0 3,9G 0% /sys/fs/cgroup /dev/sda1 511M 132K 511M 1% /boot/efi tmpfs 786M 0 786M 0% /run/user/0No I didn’t tweak the MariaDB especially for Kopano. I used the standard settings that came with the Debian 9 installation. The same with the server.cfg.
Where do you see those sql-requests? Do you mean the mysqld processes in the htop screenshots?
Actually after the first backup of the whole kopano DB (mysqldump). It looks better:
The memory usage still increases, but much much slower.
How is things in you installation? How much memory is used on your systems? Don’t you have so much mysqld processes?
Thank you for your answer.
Regards,
Alex

@sniks6 said
Don’t you have so much mysqld processes?
Only one mysqld and one kopano-server. Currently only waiting.
Better question is why so many kopano-servers? -
…soorry :-D
What i want to say is “how many sql-processes are you running”. But you’ve answered the question. You are using default values.
Is it possible to post your server.cfg and the mysql.cnf (maybe /etc/mysql/mariadb.conf.d/50-server.cnf)?
Another “thing” i see, your server ist running in german language. Did you try to run it with locale “none” or an english locale?
For locale “none” it is mandatory (in my seight) you setup the Kopano-Defaults in /etc/default/kopano with UTF-8 (german) locale. This file, maybe, is not there in a new installation.How is things in you installation?
I’ve running many server out there with different setup’s (Metal an VMs). All running Stretch without problems.
How much memory is used on your systems?
The most of them running with only 4Gigs, other (more users) with 8 to 16Gigs.
But, i allways move WebApp or Gateway to a different machine. With VMs this is often the same Hardware, but a own VM.Don’t you have so much mysqld processes?
Yes and no. If eg. search-server is running a reindexing-process all, kopano-server and mysql memory and CPU-usage, are growing up, but went down to normal values if the job is done.
What kind of virtualisation are you using?
-
Thanks four your answer. I’m using a Windows 2016 Server HyperV Core for virtualisation.
Is there a way I could reduce the number of kopano-server processes? The start immediately after running “systemctl start kopano-server”.
Btw it’s the same with the mysqld processes. They all start right after running “systemctl start mysql”. Hmmm…Kopano config is pretty standard. Here you go:

After a little research I found out that htop is showing all threads of one process by default.
Here is a picture of htop after diabling it. Just one process as you said. :-)

Hej Alex.
Okay, this looks pretty simple ;-)
I don’t have much XP with HyperV. Maybe there is a bottleneck within.
Some other questions first…- Which hardware (SCSI, SAS, FC, SATA or iSCSI? RAIDn?) is underlaying for use with the VMs? Specially for Kopano?
- Had HyperV created one single file for the VM? (i think yes) …thinprovisioned? This meen “sparse files”?
- And, how many users do you have on the system?
-
Hi Marcus,
at the moment everthing looks good. The memory usage will stay in normal range.
To answer your questions:
Which hardware (SCSI, SAS, FC, SATA or iSCSI? RAIDn?) is underlaying for use with the VMs? Specially for Kopano?
Intel RAID Controller RS2BL040
3 x WDC WD5003ABYX 0 500GB HDDs
RAID 5Had HyperV created one single file for the VM? (i think yes) …thinprovisioned? This meen “sparse files”?
Yes, one VHDX file
And, how many users do you have on the system?
Just three users. It’s a small system for my business-partner and my wife. :-)
Anyways the MariaDB shows 5GB in phpmyadmin the attachements folder is 84GB:root@kopano:~# du -sh /var/lib/kopano/attachments 84G /var/lib/kopano/attachmentsI moved from an old Zarafa installation via kopano-migration-imap to the kopano system.
That’s why the DB is that big right from the start.But just as I said , at the moment the system runs good.

…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?
