SocketException: Too many files open

I had a similar problem and so I did a dump of the file descriptors being used by my app using lsof -p <process id>. Below was just some of the items shown. Over 1000 file descriptors were open.

I noticed that the ports used were related to JMS, specifially the 8093 port.
I went back to my code and noticed that I was leaving my connections to JMS open and wasn't closing them. After closing them and re running everything was fine.

Hope that helps.
