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.
