Subject Re: Memory leak in UIMA-AS ?
Date Thu, 15 Apr 2010 15:04:00 GMT
Jorn, I will try to find a source of this leakage today. There is  a per CAS
statistic cached in a Map in the UIMA AS service and most likely this Map is
not being cleaned up every time a CAS is returned to a client. I will create
JIRA for this once I confirm the problem.
Thanks

Jerry C
