This is in general a problem of a multi-threaded (like the qmaster) application with LinuxThreads:

"GNU LinuxThreads are visible using the ps command line utility, and each thread, or process, uses one entry in the kernel's process table, generally limited to 512 processes."


Note that newer Linux kernels (2.6.x) use a different thread implementation, and you will see only 1 process for a multi-threaded application.

If you have another machine with a different OS running X, then add that machine as submit host, and try to use qmon to submit a job on that machine. I think the problem with qmon that you are seeing is related to the X implementation on Redhat 7.2.
