Tomcat process needing to communicate via soap and remote system takes too long to timeout hence tomcat processes are lying around wasting fd. Another common issue is DB bottlenecks once again causing tomcat processes to lay around for too long and as a result don't get freed up fast enough to further serve clients. Also you need to see how many connections are coming in to your system using any network monitoring tool you can put on, it could really be just that you are reaching fd limit and hence must edit your ulimits.Hope this helps. /Jason
