A thread dump is a log containing information about currently running threads and processes within the Java Virtual Machine (JVM).
If your application is performing poorly, behaving unexpectedly or stops responding, you can generate a thread dump to help diagnose the cause of the problem. If you create a support request, including a thread dump into a support zip can help the Atlassian support team investigate your problems.
