Description

I created a JAX-RS 2.0 service, then I used apache benchmark to create some load on the web application. After some tests ab failed.

Completed 18000 requests
apr_pollset_poll: The timeout specified has expired (70007)
Total of 19997 requests completed

While the test finished and no HTTP requests hit, the application container is still consuming all available CPU time, and it has some threads like this in the thread dump:
