Hi Prasanna,
We haven't seen this kind of deadlocks before. Could you describe a bit
about what you are doing that causes this error? Is the CMS running in
the same weblogic instance as the repository? Can you check if there are
dubplicate jars of httpclient (in shared lib folders)?
Regards,
Bart

Hi all,
We are facing deadlock issues when running hippo cms 6.05.02 in weblogic
10.1.
But the application works fine in Tomcat, only when running in weblogic
10.1, it results in deadlock.
We are analyzing the thread dumps right now
If any of you have any thoughts on how to solve this issue, its greatly
appreciated.
