I have an IBM Thinkcentre with a RHEL5.1 client installation fully
updated. The system runs on init level 3. Gnome/KDE package groups are
not installed. The package groups installed are Administration Tools,
Editors, System Tools, Text Based Internet & Server Configuration Tools.
This system has Nessus-3.0.6 installed using the rpm acquired from
nessus.org.
The problem is this... the system slows to a crawl after random time
durations. Trying to login via ssh from a remote system takes up to 5
minutes and a Vulnerability Scan of a subnet with 60-70 systems is known
to take a day! The usual time for this job is less than 10 minutes. If I
reboot the system things go smoothly for anywhere between 30 minutes and
2 hours before slowing down again.
I went through the kernel messages log but no errors or hints to the
problem were found. I even created a *.* entry in syslog.conf to capture
all possible logs into one /megalog/ but found nothing out of place.
I don't suspect any problems in the hardware as until last week this
system was doing the same task running Fedora 8. No performance issues
seen then.
Any pointers? What else should I look at?
