vdump error

Hi folks,

I'm getting a very unusual error when I am trying to run a vdump on the /usr filesystem of a DS15.

vdump -0 -f /u10/usr.dmp /usr
path : /usr
dev/fset : usr_domain#usr
type : advfs
advfs id : 0x40083948.0004dae0.1
vdump: Date of last level 0 dump: the start of the epoch
vdump: Dumping directories


************* PROGRAM ABORT **************

vdump: Not enough memory to generate link table.


This happens to be an administration system, so I'm betting the kernel isn't quite tuned properly. Has anyone run across this and know the answer?

The system is running 5.1B PK4.

Regards,

Re: vdump error

Did you check the swap space available, memory available. Please post the swapon -a and vmstat -P outputs

thanks

Re: vdump error

My partner answered the question. He set all of the ulimits to "unlimited" and it worked. AS I suspected, since this is an admin box, it hasn't been kernel tuned properly.

Ulimits... we don't need no stinkin' ulimits!

Thanks for the help,
