Subject [jira] Commented: (ODE-549) Exceptions in SoapExternalService under heavy load
Date Fri, 13 Mar 2009 19:28:52 GMT

    [ https://issues.apache.org/jira/browse/ODE-549?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12681871#action_12681871
] 

Alexis Midon commented on ODE-549:
----------------------------------


Fix committed in branch 1.X r753357
Exception #1:  fixed with a read/write lock on the WatchDog
Exception #2:  fixed by taking a lock on the AxisConfiguration instance.
This issue occurs only with Axis2-1.3. Actually Axis2-1.4 has fixed ServiceClient with better
synchronization.

Wait for feedback from users before closing the issue.

> Doing some quick benchmarking with in-memory processes (so when we start having a lot
of invocations happening in parrallel), I get quite of few NPEs and AxisFault in SoapExternalService.applySecuritySettings().
I've pasted the stacks below and attached the logs for more.
