-------------------------
Summary: MAPCodec: Memory leak due to growing uncorrelatedExchanges
Key: CXF-7943
URL: https://issues.apache.org/jira/browse/CXF-7943
Project: CXF
Issue Type: Bug
Affects Versions: 3.2.0
Environment: CXF 3.2.0, JDK 1.8
Reporter: Sean
Attachments: histogram.PNG, leak_suspect_1.PNG
When running load tests, my system begin to get memory leak after 4 hours or
so. When analyzing the heap dump using VisualVM (please see attachments), I can
see that a ConcurrentHashMap is taking up 1.7 GB of space in the heap, as well
as being the main "suspect" for this leak. This leads me to believe that it is
the uncorrelatedExchanges attribute since this map is being reference from the
MAPCodec class.
I believe that the map, in my case, for whatever reason, does not always remove
the Exchange after the synchronous request/responses are done, however I could
be wrong.
IF this is indeed a bug, what could the cause of this be, as well as any work
around?
