i am not able to login the server through SSH session, by my user, however other OS users are able to do so.
while trying to su the user through root, i get "su: cannot set user id: Resource temporarily unavailable"

kindly Suggest

thanks,
Arif

It is generally an issue with maximun no. of processs reached by your username. So check your processes, as:

Code:

~$ ps -aef | grep <username>

And kill some of them which are either not necessory or have finished but still alive like any open terminals or sessions (just close them), as:

Code:

kill <pid>
OR
kill -9 <pid>

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:

Code:

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

@Aarif:

You can Mark the thread as solved (option is under Thread Tools on top menu), if you think it has so.
