How do I check file descriptors limit?
To display the current user limits, use the ulimit –a command. The nofiles parameter is the number of file descriptors available to a process. When IP:PIPE or IP:SPIPE are used for agent connectivity, persistent TCP connections are maintained to each agent, and each connection requires a file descriptor.

The file-nr file displays three parameters: the total allocated file handles. the number of currently used file handles (with the 2.4 kernel); or the number of currently unused file handles (with the 2.6 kernel). the maximum file handles that can be allocated (also found in /proc/sys/fs/file-max).

File descriptors are generally unique to each process, but they can be shared by child processes created with a fork subroutine or copied by the fcntl, dup, and dup2 subroutines.
