Environment

Novell Open Enterprise Server (Linux based)

Novell SUSE Linux Enterprise Server 9

Situation

Unable to login as a particular user Unable to start an SSH session as a particular user Unable to "su" as a particular user All the processes started by the affected user stop working ERROR: su: cannot set user id: Resource temporarily unavailable

Resolution

The affected user has reached the maximum number of process specified for him into the file /etc/security/limits.conf . These commands, executed as root, can give you the number of process and of open files for the given user: ps -U username | wc -l lsof | grep username | wc -l To fix the issue increase the NPROC Soft limit according to the user and applications needs; please look at the note below about the /etc/security/limits.conf file. If third party software is involved, please contact the software vendor to advice about the proper limits to use.

Additional Information

The following is an example configuration file: # EXAMPLE /etc/security/limits.conf file: # ======================================= #      *          soft   nproc       2047 *         hard   nproc       16384 *         soft   nofile       2048 *         hard   nofile      65536

Having this file means, for instance, that every user can start a maximum of 2047 processes and can raise this limit up to 16384.
