However the locking is slowing down the > server in some cases, and is a ticking time bomb that needs to be addressed. > As part of this too we need to be sure that the Cleaner and Intermediate to > Done migration threads handle exceptions properly. Now it appears that the > exception is logged, and the thread just shuts down. This means that the > history server could still be up and running for weeks and never remove old > jobs. -- This message is automatically generated by JIRA.
