[Pkg-giraffe-maintainers] Bug#941610: kopano-server crashes

Wed Oct 2 19:16:03 BST 2019

Package: kopano-server
Version: 8.7.0-3
Severity: normal

Dear Maintainer,

while running Kopano, I'm experiencing kopano-server crashes. At the
time of the crash, there are no emails being delivered via Postfix, nor
are there entries in the Apache access log that point to usage of Z-push
or Kopano Webapp. Also, during that time nothing is logged in the
gateway log, ical log, or any other Kopano logs. So I cannot point to a
probable cause.
Please note that I have seen these crashes on at least four of our
systems so far. They seem to happen once every two weeks, on average.

If there's anything I can do to help getting this fixed, please let me
know.

Kind regards, Roel
