Slow 'su' to users other than root

[cgswong]

Hi all,

Over this week I've noticed that 'su' to any user but root takes up to 60 seconds. It's not the su itself though that takes so long it's the actual login after entering the password (if not done as root) that takes the 60 secs. If su is done from root to another user the same problem exists. It only is fast is su is done to root. Also, I've noticed that telnet to the server is also quite slow and takes awhile to come back with a login prompt.

Does anyone have any ideas as to what might be wrong? Any help is appreciated.

Thanks.

when did this problem start?

do your users have profiles
or processes that run at login time
that may slow down the login process?

have you checked cpu utilization
for this system?
could some process be hogging the cpu? Robert G. Jordan

I believe it started a little after we installed Volume Manager. CPU and Disk utilization are okay. It has two Oracle databases (2GB RAM, 4x400MHz CPU).

No login scripts are being run.
