JM,

Client is run remotely and it is not on cron. CPU usage seems okie.
I will run the bash script and monitor the situation.

Thanks,
Edy

Are you running this in cron? Do an uptime now to see what your load average
is or a vmstat would work as well. If your load is fine now, then write a
quick bash script to run just before nessus, and get it to do periodic
snapshots:

-----snip-snip--snip

#!/bin/bash

for((i=0;i<20;i++))
do
echo "Snapshot: "`date` >> profile.log
echo >> profile.log
echo "Uptime: " >> profile.log
uptime >> profile.log
echo >> profile.log
echo "Free: " >> profile.log
free >> profile.log
echo >> profile.log
echo "Vmstat: " >> profile.log
vmstat >> profile.log
echo >> profile.log
echo "End of Snapshot ---------" >> profile.log

sleep 60
done


-----snip-snip--snip

This was just typed into Outlook so I would test it first but essentially 20
minutes should be sufficient to determine if you are running into resource
starvation during your nessus runs. You could also add some ps information
if you wanted to...

Anyone know what causes this?
