I having the following memory management problems on a brand new
AlphaStation 500/500 with 1gb RAM and 5gb swap (DEC Unix 4.0):
a. when a large process is running (eg., 900mb) at nice=20, then if
someone types "ps aux", the command hangs for a long time until
the entire process is swapped out to disk (0% resident). When a
medium-sized process is running (eg., 650mb) this does not happen.
b. when swapping occurs, "swapon -s" indicates that both swap disks
are getting roughly equal use even though rz1c has higher
priority in the /etc/fstab
/dev/rz0a / ufs rw 1 1
/dev/rz0g /usr ufs rw 1 2
/proc /proc procfs rw 0 0
/dev/rz1c swap1 ufs sw 0 2
/dev/rz0b swap2 ufs sw 0 2
and I have "ln -s ../dev/rz1c /sbin/swapdefault"
This is particularly annoying since rz1 is _much_ faster than rz0.
Thanks for any suggestions,
Eric
P.S. Another annoying thing is that the /usr/sbin/advfsd demon is
using up memory and cycles even though I am not using advfs!
How do I kill this demon? Is there any reason not to kill it?
