File descriptor limit

Open Server hangs when it exceeds the file descriptor limit. Upon exceeding the limit, Open Server reports the following error and then hangs:

SRVLIB Message: Test_ctos  - 16240/10/0: Net-Library routinenet_accept() failed in srv__conserviceNetwork error: status = 159 - Error string not available

The workaround is to increase the file descriptor limit to a larger value, for example, 8192.
