paging space almost full

[michaelvv]

Other than re-booting, how does one reclaim paging space? There is hardly anything running in the system, CPUs are 98-99% of the time idle as reported by vmstat, but the paging space is 82% full. OS is AIX 4.3.3. Suggestions are appreciated.

Why do you want to reclaim it?? Memory is too expensive to flood with stuff that's not needed.

If something is filling up paging space it's because it's not used. Just leave it there.
The best way to reclaim it is to shut down the process that's using it.

Thanks Henrik. A while back, the paging space was full, and the machine as you would expect was extremely sluggish. I wrote a script to check periodically how full the paging space is, and send e-mail when it is more than 80% full. My problem is that I do not know how to identify the process that is doing it. It is only a matter of time before it gets full again and the machine grinds to a halt

Never mind, I found them...

Can you share this script of yours that checks the paging space?

It is not a script, it'a write up on memory leaks, which you can find at

http://www.ibm.com/server/support.

I can email it to you if you let me know where.

Would you mind email to me
Thank you for your help

Dear michaelvv,

Could you e-mail the script to me too ?

Thank you.

Here is a copy of what I am using to do the same, nothing fancy:

#=====================================
# Check Paging Space for values > 79% |
#=====================================
typeset -u HOST=`hostname`

for ps in `lsps -s | grep % | awk '{print $2}' |tr -d '%'`
do
case ${ps} in
80|81|82|83|84|85|86|87|88|89|90|91|92|93|94|95|96|97|98|99)
echo "WARNING: Paging Space Utilization on $HOST has reached ${ps}%!!" | mail -s $HOST you@work.com
esac
done
