@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.

darootler

@fbartels

Sure, thank you.

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.
