edit the file /etc/init.d/tomcat and add:
ulimit -Hn 16384
ulimit -Sn 16384

Check if it resolves (you may need to restart)

As salil pointed out

edit the file /etc/init.d/tomcat and add:
ulimit -Hn 16384
ulimit -Sn 16384

followed by restart the tomcat should increase the limit, this was a bug in ubuntu and has not been resolved yet.

I am running Ubuntu 12.04.2 and run the updates manually on a regular basis from the command line. I noticed that the Kernel gets updated too often...
I know I am supposed to reboot the machine after a Kernel update, but that means rebooting every two days. One of the things I like to do is run the uptime command and smile :-)
1. Why does the Kernel get updated so often?
2. How do I find the change log, so I can decide if I need to update / restart the machine?
