Incident: kopano-search and kopano-presence services not stopping gracefully

Date Seen
Approximately 05.12.2016, this problem occurs since Zarafa 7.2.3.

Versions
Ubuntu 16.04.1 LTS
Kopano 8.3.0-534
Apache 2.4.18
MySQL 5.7.16

Bug Description
Stopping the kopano-search or the kopano-presence service cannot be done gracefully and will be timed out. The processes will be killed by systemd.

Severity
Major

Steps to Reproduce
Stop kopano-search or kopano-presence service and review the logs:
0_1483745130023_upload-ff772b20-7021-4914-bee9-6b366d94c506

Actual Behavior
It’s not possible to stop kopano-search and kopano-presence gracefully. Systemd kills the processes after a 30 second timeout wich leads to unexpected reboot times.

Expected Behavior
The processes can be terminated gracefully.

Troubleshooting/Testing Steps Attempted
Maybe there are some changes needed in the init scripts. I didn’t touch them.

Workaround
Just sit back and wait an extra minute.

I just upgraded to Kopano Core 8.3.0-585 and this problem is still present.

@fbartels

I am still having this issue. Any suggestions? Any ideas?

This is driving me crazing because sometimes Ubuntu won’t shutdown and just hangs during a reboot…

Regards
Richard

I am able to pinn down the problem:

kopano-presence and kopano-search is stopping well if “log_method” is set to “file”. If “log_method” is set to “syslog” both services will not stop properly.

Can someone confirm this behavior?

Regards
Richard

I see the same issue with kopano-search. I have not tried to change my log_method from syslog to file, however.

With log_method set to syslog kopano-search also does not stop gracefully for me.

@fbartels

Could you please reopen the related ticket and update it?

Thanks
Richard

@darootler I still want to reproduce the error locally so that I have something on hand to give to a developer and verify the fix. Once I had time to do so, I’ll create a new ticket.

@fbartels

Sure, thank you.

Regards
Richard

ok, with the additional of information that syslog logging has to be enabled for the error to occur I was able to reproduce this isse. https://jira.kopano.io/browse/KC-643 has been created to resolve this issue.
