frequent Confluence crashes

[Kris W]

Our Confluence instance crashes several times a week. About half of the crashes happen in the middle of the night when the system is running an automatic daily backup of the MySQL databases.

Is there a way to keep Confluence from crashing when the database is being backed up?

Is there a way to monitor Confluence, and restart it if it crashes?

I can't find any clues in the logs. atlassian-confluence.log doesn't show any entries at the times of the crashes.

Tell us a bit more about your environment.  Is MySQL running on the same server as Confluence?  Are there other processes, such as backups (in addition to MySQL backups) running at the same time?

It's an 8GB cloud server. It's also running MySQL, as well as Apache. It's also running Crowd and Jira.

Maybe Confluence is running out of connections. Maybe increasing the connection pool can resolve the issue: https://confluence.atlassian.com/doc/performance-tuning-130289.html#PerformanceTuning-Databaseconnectionpool.

Thanks, Guilherme.

I'll try the thread dumps mentioned in that tip to see if that gives me some better data.

It seems like that wouldn't be the problem, though, since the crashes that are happening in the middle of the night are at a time when I don't think anyone is actually using Confluence.
