APAR status
Closed as program error.
Error description
When movement of the primary catalog occurs because of detected failures, and concurrent container failures are detected by the catalog server, this memory leak can be more prevalently seen. LockTimeoutException exception instances can take up a bulk of the memory because the exception messages contain the entire list of keys that are locked for particular transactions.
Local fix
TBD
Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere eXtreme Scale. * **************************************************************** * PROBLEM DESCRIPTION: Out of memory errors can occur in the * * catalog server, especially in larger * * topologies with numerous partitions. * **************************************************************** * RECOMMENDATION: * **************************************************************** The cause of the memory leak had to do with a placement state that was not cleared correctly. The logic was updated so that now the state is cleared correctly. Additionally, the LockTimeoutException exception class was updated to stop creating additional message text after a threshold is reached. Now, when including the keys that are locked in a particular transaction in the exception message, only a subset of the keys that have been locked in the transaction are included, instead of including all of them if the number of keys is greater than the threshold.
Problem conclusion
An interim fix is available for this APAR.
