Hello, Users are getting intermittent error "Service Unavailable - Zero Size Object" while accessing some pages. We use Apache 2.2.11 with Prefork MPM. The backend is Jboss. However, there is no indication of any errors either in Apache or Jboss. I have tried looking at other places that experienced this error. For them this was all related with PHP. In our case, we don't use PHP. I have also tried restarting the Webserver but didn't make any difference. If anyone experienced this issue before, then please help. Your help is really appreciated. Thanks Techie
