Encountered an error when I was trying to su to a user:

# su -s /bin/bash user
su: /bin/bash: Resource temporarily unavailable

ps showed they had many processes open, which was hitting a limit.

# ps aux | grep user | wc -l
1624

Resolved by killing all their processes.

kill -9 $(ps aux | awk '/user/ {print $2}')

rpmdb problems: $package is a duplicate with $package. Openmanage: Failed to start because system is not supported.
