Too many files open (UNIX and Linux)

The Too many open files message occurs on UNIX and Linux® operating systems. The default setting for the maximum number of open files might be too low.

To avoid this condition, increase the maximum open files to 8000:
  1. Edit the /etc/security/limit.conf file.
  2. Change the statement that specifies the value of nofiles to 8000.
  3. Optional: If you want the change to take effect in the current session, type ulimit -n 8000.
