Upgrade core 11.0.1.2 to 11.0.2.41 - High search cpu usage

icey

Hi All,
same here. Fresh installation, just 6 users added, no big data yet as it is not yet running in “production”.
Core 11.0.2.43, as soon as kopano-search is started the CPU is at round about 50% continually. A service kopano-search stop takes its time and then CPU drops to 1%, everything is fine.
In the log of k-search:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/kopano/log.py", line 140, in log_exc
    try: yield
  File "/usr/lib/python3/dist-packages/kopano_search/__init__.py", line 200, in main
    path = folder.path
  File "/usr/lib/python3/dist-packages/kopano/folder.py", line 250, in path
    subtree_entryid = self.store.subtree.entryid
  File "/usr/lib/python3/dist-packages/kopano/store.py", line 242, in subtree
    return _folder.Folder(self, _benc(ipmsubtreeid))
  File "/usr/lib/python3/dist-packages/kopano/folder.py", line 145, in __init__
    self.mapiobj
  File "/usr/lib/python3/dist-packages/kopano/folder.py", line 158, in mapiobj
    IID_IMAPIFolder, MAPI_MODIFY)
  File "/usr/lib/python3/dist-packages/MAPICore.py", line 602, in OpenEntry
    return _MAPICore.IMsgStore_OpenEntry(self, cbEntryID, lpInterface, ulFlags)
SystemError: <built-in function IMsgStore_OpenEntry> returned a result with an error set

Anyone an idea?
Thanks in advance

Dear all,

does nobody has an idea how this could be fixed? It is weird, cause actually there is nearly nothing to be indexed by now. Nothing in attachements folder and also approxiametly 12 mails in all mailboxes.
Would be great if anybody could help.
What about the others? Probs solved?

Thanks in advance,
Icey

I experience same issue.

I am not on mariadb, but on mysql.

My sql is not part of the same machine. I can confirm mysql is very stable and no performance issues. It does not appear the issue is with the database server.

On the application server for Kopano, yes I can reach high cpu usage for both kopano-server and kopano-search after several weeks of uptime.

My only workaround is a restart of kopano-server, kopano-search

How can we debug this further?

Hello @icey ,
I fixed the possible cause some time ago, but didn’t have time to create a qualified PR, yet.
You can resolve the problem by replacing a few lines in /usr/lib/python3.6/site-packages/kopano_search-11.0.2-py3.6.egg/kopano_search/__init__.py (the exact path on your system depends on distribution, python- and kopano-version).
Take a look here.

bg,
umgfoin.

In your case more likely to be found here: /usr/lib/python3/dist-packages/kopano_search/__init__.py

Yeah - and an impressively minimalistic one ;-) …
Thanks!

The fix from @umgfoin is great! Works for me either!

Thanks a lot.

naspelupo

Yep: fix did the trick. Load is normal again!
Many thanks for this!

This edit plus a reboot fixed the high CPU for me too, now CPU is negligible.

core-11.0.2.43

@umgfoin Thank you very much! That did the trick for me too :)
Kopano 11.0.2, running under Ubuntu 18.04 as LXC on QNAP NAS.

@umgfoin thank you so much. It also works in supported version 8.7.23 and Debian 10.

The fix also works for my environment: KC 8.7.23 and virtual ucs-4.4.8 on a QNAP NAS. Thx a lot ;-)

JungleMarc

I applied the patch. Thank you for getting this fixed. :)

index_processes = 1 in /etc/kopano/search.cfg

Made a big difference on system load during cache rebuild.

Just to have it said, the fix is part of the nightly releases for a few days already.

@fbartels amazing. :)
