File descriptors (ulimit)
Specifies the various restrictions on resource usage on the user account.
Check the change with the following command
# ulimit -a ... open files (-n) 2000
Perform the following steps to change the open file limit to 10,000 files. Edit the /etc/security/limits file.
nofiles = 10000 nofiles_hard = 10000
Save and close the file, logoff from the system, and logon again
