Solution

Increase the pollfd file descriptor limit. There are two ways to do this:

1. Execute ulimit -n 8193 on the shell as root.

2. Increase the hard limit on the number of file descriptors to 8193 or higher:

   1. Check the hard limit with ulimit -n -H.

   2. If less than 8193, edit /etc/system, adding the set rlim_fd_max=8193 command.

   3. Reboot the machine.
