[Galder Zamarreno (JIRA)]

    [ https://jira.jboss.org/jira/browse/JBAS-6311?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12442099#action_12442099 ] 

Galder Zamarreno commented on JBAS-6311:
----------------------------------------

In this sense, it'd be interesting to find out how Spring/Tomcat do
the following as per http://www.springsource.com/products/suite/tcserver:

"- Application thread lock detection provides warnings when threads 
compete for restricted resources in a way that would compromise application 
integrity"

> We could really do with a service within AS that automatically generates 
> local/remote thread dumps under certain circumstances:
> - When a JBC TimeoutException is received or a sync cluster wide RPC 
> sync call times out. request the node that didn't respond to dump a thread 
> dump. It could happen that the node wouldn't respond to such request either.
> - Maybe if a deadlock was detected locally? Not sure how a service could 
> be notified of such deadlock, maybe it'd require to poll find deadlocks periodically.
> Remote thread dumps would have to over JMX or similar but local thread 
> dumps could either be done via JMX or natively. Some work was done trying 
> to to automate generation of thread dumps if servers fail to stop during testsuite:
