I have an SGI running IRIX 6.5
The prob is when i login as user
and open a file , it gives me error as "OUT OF MEMORY"
when i su or login as root . THis error disappers
I have lot of space in the System .

Thanx

You may have a lot of space, but does your user name have access to it???

Ya i have access for all users.
It happens also for files in its home directory.
i canalso make new files . But every time i open a file using vi , it gives me this message at the Escape mode prompt
" Out Of Memory"

what is your swap size and ram size? Are they equal? And I know it's ok when you are root... but that just seems strange.

swap -s
total: 0.00k allocated + 53.11m add'l reserved = 53.11m bytes used, 326.03m byte
s available
swap -l
lswap path dev pri swaplo blocks free maxswap vswap
1 /dev/swap
0,203 0 0 262144 262144 262144 0

I am not aware of the RAM size though

Do you have quotas' on your filesystem space? If so, that could be your problem. I don't know the specifics, but I believe there are ways to limit the RAM and CPU usage for particular users as well...

DPAI,

You need to run the command " top " as root.
#top

This will give you number of processes running, sleeping
CPU load in percentage used by CPU and user
Memory Available and being used
Swap space being used and free
etc...

...By the way the output of 'top" is in REAL time which will help you find the culprit that is hogging your memory.

Good Luck.
