I would really appreciate if anyone out there knows about any kind of tools that I can run on my Advanced Server 2.1update3 running kernel 2.4.9-e.34smp, box so it can capture hangs and slow-downs while a performance test is run.
Lately, during user logins and perf testings, we have experienced slow-downs and hangs on the box where the box stops responding for a few seconds and when it does respond, it acts very slow. Even ls -la commands are slow. I don't know what's happening. It's hooked up to a fast Ethernet LAN, dual CPU 2.0GHz, with 2+GB memory and large harddrives with lots of unused space. We used Sun Fire V20Z and IBM x325 with same OS/configuration. They are cheetah fast and produced excellent numbers in perf tests, but both have shown instability.
Please help with your thoughts and ideas.

watch /var/log/{debug,syslog,secure,messages} before/during/after the problem.
cd /var/log; tail -f messages syslog debug secure ..see man tail to see -f
