Subject [jira] Commented: (UIMA-1766) Fix Memory Leak in UIMA AS Cas Multiplier Service
Date Mon, 19 Apr 2010 09:16:50 GMT

Jörn Kottmann commented on UIMA-1766:
-------------------------------------

My test shows that the issue is fixed now. A test instance analyzed 650K CASes and in the
memory dump only 38 instances of the ServicePerformance object exist.

> When running an Aggregate with a colocated Cas Multiplier per CAS statistics are not
being removed from a Map maintained by the Cas Multiplier service. As more CASes are sent
to the CM, instances of ServicePerformance object are added to the Map and never removed leading
to a memory leak and eventual OOM error.
