Emmanuel Lecharny commented on DIRMINA-653: ------------------------------------------- Hmmm.. The buffer does not contain compressed data. Anyway you can get a stack trace ? > IoSession.write not thread-safe? Loosing messages under heavy multi-threaded > write on same session. > --------------------------------------------------------------------------------------------------- > > Key: DIRMINA-653 > URL: https://issues.apache.org/jira/browse/DIRMINA-653 > Project: MINA > Issue Type: Bug > Components: Core, Filter > Affects Versions: 2.0.0-M4 > Environment: Windows Vista 64-bit > Reporter: Mauritz Lovgren > Fix For: 2.0.0-M5 > > > I am writing a stress-test that tests multi-thread safetyness of our > stateless encoder / decoder under heavy load and I am observing that messages > are silently lost during session.write(Object), (the lost messages do not > seem to reach the underlying socket buffer at all). > I am using one encoder / decoder that is stateless. No executor filter, only > the filter codec and a basic io handler. > Synchronizing on the session.write makes the problem go away; > synchronized (session) > { > future = session.write(message); > } > Do I really have to synchronize on the session to solve this issue? -- This message is automatically generated by JIRA.
