[jboss-user] [Performance Tuning] - java.net.SocketException: Too many open files on Red Hat lin

Dear All, We are using JBoss 4.2.2GA on a RHEL with Apache as Webserver. We keep running out of open files whenever after just hrs since the JBoss server is started. We also increased the ulimit max open files number ffrom 1024 to 8192 but still we seem to be maxing out this number after a few hrs or when doing load testing. The application that is running on the JBoss server makes HTTP connections to other systems using Apache HTTPClient and the code is releasing the connections using the HTTPClient. can somebody pls help with this issue. JBoss 4.2.2 GA, RHELinux -- Quad Code 8GBRAM, There has been some internal JBoss errors which started occurring at a rapid pace and the server.log went up from 900kb to 350mb in a span of 30-60mins.
