Error 'su: /Bin/Bash: Too Many Open Files In System' When Switching to Non-root User on Enterprise Linux [ID 1187463.1]

Applies to:

Linux OS - Version: 4.4 and later [Release: OEL4U4 and later ]
Linux x86-64

Symptoms

You get the following error when switching to non-root user by 'su':
su: /bin/bash: Too many open files in system

Cause

System-wide resource threshold file-max exceeded.

Solution

Increase the file-max value, e.g.
#echo "6553600" > /proc/sys/fs/file-max

You can add the following line in /etc/sysctl.conf to keep the setting cross reboot:
fs.file-max=6553600
