[jaikiran pai (JIRA)]

    [ https://issues.jboss.org/browse/AS7-3811?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12669109#comment-12669109 ] 

jaikiran pai commented on AS7-3811:
-----------------------------------

That exception stacktrace might even mean a genuine wait where the client is waiting for a result from the server. I'm looking at the perf setup currently with regards to a couple of other JIRAs around this and that might help understand what the problem is.

> IMHO a client must support a timeout. Very often when things go wrong the clients get stuck indefinitely.
> Maybe this problem go even deeper, something on the server failed but didnt reply to the client. This is often encoutered during failover undeploy test (50 of 200 clients got stuck :-) ).
