Team Calendar and Heap Memory Outage

Greetings,

Recently we got random error where with the team calendar and confluence hangs every 1-2 hours, which is totally unusable. 

The calendar id (subCalendarId=xxxx) is different every time hence we don't think it's about data corruption of a specific calendar. 

org.apache.catalina.valves.StuckThreadDetectionValve.notifyStuckThreadDetected Thread "http-nio-8090-exec-3" (id=205) has been active for 66,801 milliseconds (since 6/7/18 1:03 PM) to serve the same request for /rest/calendar-services/1.0/calendar/events.json?subCalendarId=ef9d4cb4-2824-46d5-bfac-17b4dfbcae4f&userTimeZoneId=UTC&start=2018-05-08T00%3A00%3A00Z&end=2018-07-08T00%3A00%3A00Z&_=1528376613717 and may be stuck (configured threshold for this StuckThreadDetectionValve is 60 seconds). There is/are 2 thread(s) in total that are monitored by this Valve and may be stuck. java.lang.Throwable

After a few times, the following error occurs and the whole confluence went down.

We have already increased the heap size from 2GB to 8GB which doesn't help.

Thanks.

Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "C3P0PooledConnectionPoolManager[identityToken->319iuf9v1og22t1ghyd3k|76c4ebbf]-HelperThread-#0"Exception in thread "pool-1-thread-1-Logging Task Scheduler" java.lang.OutOfMemoryError: Java heap spaceException in thread "ContainerBackgroundProcessor[StandardEngine[Standalone]]" 07-Jun-2018 11:16:08.029 WARNING [main] org.apache.tomcat.util.digester.SetPropertiesRule.begin [SetPropertiesRule]{Server} Setting property 'debug' to '0' did not find a matching property.

If you are still getting out of memory errors after raising the heap we should take a closer look at your logs and configuration files. I opened a ticket for you on our support portal, and sent you a request for a support zip to be attached to it.

We can circle back to this thread once we have a resolution to share.

@AnnWorley Was there any resolution to this issue?

We are facing something similar.

Hi - the support ticket is still open but one thing I can share from it is that there is an open bug report, with diagnosis and workaround that may fit your case: Deleting repeating Events in Team Calendar causes duplicates in database and java.lang.OutOfMemoryError
