[torqueusers] internal socket table full log message

ulimit is not what is causing this problem. The error comes from an internal table full problem. In TORQUE 2.5.5 the table size is 10240. 

How busy and large is your system? Do you have lingering sockets. Try netstat and see how many open tcp connections you have.

Anyone has any idea about this message? Due to this message, no one was able to run the jobs and I had restart the service.
