Hi gurus,
Running Solaris 8 on a E420, 2gb mem, 2gb swap configured .....
Need some help with a problem we are having with swap .... For the past couple of days "something" is using ALOT of swap space and periodically filling up /tmp ... I can't seem to find what it is. It happens for a while, and the capacity of /tmp fills up, then goes down and keeps fluncuating like so .....
Is there a command to run to see what is using all the swap space ?
Why does the "kbytes" column in "df -k" go up and down, I thought this would be constant .....

The kbytes column for swap doesn't seem to reflect what we have configured for the system ????
