I am running RHEL 6.2

I am getting the following problem:

[root@nevada02 ~]# su - mqm
su: cannot set user id: Resource temporarily unavailable
[root@nevada02 ~]#

Open in new window


I check some resources, but everything seems fine

[root@nevada02 ~]# free -m

Please do 'ulimit -a', 'ps -U mqm | wc -l', 'lsof | grep mqm | wc -l' and paste the results.

Also, check in /etc/security/limits.conf
