JTA transaction unexpectedly rolled back (maybe due to a timeout)

[Qingsong Zhang]

Our Bamboo (v3.3.2) server shows following errors on many agent:

(org.springframework.transaction.UnexpectedRollbackException : JTA transaction unexpectedly rolled back (maybe due to a timeout); nested exception is javax.transaction.RollbackException: Unable to commit: Transaction timeout)

Any clue on what's going on?

It sounds like you have some communication issues on your network - or maybe you've restarted your Bamboo server? It'd be best if you contacted support about that.

Note that the error itself is harmless and you don't need to worry about that as long as you don't experience other problems with you builds.
