Seam app hangs under heavy load (InUseConnectionCount goes very high)

demetrio812 Jan 16, 2011 8:26 PM

Hello,
I've just add a bad day with an app under load: it worked normally but at a certain point (after 2-30 mins) the InUseConnectionCount raise from 10 to 150 and more and the application hangs.

The thread dump shows a lot of threads BLOCKED:

It's not related to my bane's method as every thread is BLOCKED from different methods (but all in the same point, CachedConnectionManager.unregisterConnection(CachedConnectionManager.java:318)) so I'm trying to figure out how to understand who generates all these connections...

Is there a way to track it?

I cannot reproduce in local even if I run a JMeter test (maybe it's something originated by a javascript attached method)...

Here there is the screen shot of what happened:

1. normally (during the load) it was like this: http://blog.brightwide.com/normal.png
(I still don't understand the peaks)

2. when it was completed blocked that's the graph: http://blog.brightwide.com/blocked.png

Any hint could be useful...

Thanks

Demetrio

Sorry about the posts but it seems I cannot edit my posts.

By looking at the logs I've found the following exceptions:
