Hello,

I am running jboss 3.2.1 with embedded tomcat 4.1.24 on a sun solaris system in a production environment. At random times (we assume it is related to increasing load of the server), our jboss server just hangs. This means when I open a web browser and go to the begin page, I get no response (IE screen stays white). In the server logs I see the following stacktrace (see below). Does anyone have a clue what might be the problem here and a possible workaround?

Thanks a lot for the assistance,
