Hello Every buddy
I'm checking another computer on the network. thats has an stranger
behavior. Let me explain
This is a Linux/Debian computer installed some 9 days ago. Assigned
user want to run Moodle on it.
But they called me asking why with 40 users the server went to top
processor and memory.
Hardware is a Sun-Ultra, with 2GB of RAM, and plenty of scsi disk
space...
The problem:
when I run "top" I have between 43% to 52% of processor used by
"Sys" (System Tasks)
and I cannot identify what is taking these process power.
top does not give anything using the system
nothing is being transfered (checked with iptraf)
no disk usage (using iostat)
no root kits, checked with ckrootkit some minutes ago
no programs listening, checked with netstat
I don't know which tool can help me to find the problem.
I know there should be one and am surfing freshmeat.net, but I can
happily accept any help you can give
Thanks in advance
Gabriel Orozco
