Try taking threaddumps (kill -3 <pid>)  and watch the output. Perhaps you
can see from the dump where in your code (assuming it is the web application
code) the issue is.

If you take several dumps sequentially (with an interval of a few seconds)
you can try to parse the output with tools such as Samurai (Google for
"samurai thread analyzer").

Threaddump information is usually stored in the native standard out of the
java process.
