I have 6 identical IBM blades and all are running RHEL 3, kernel
2.4.21-40.ELsmp. They are dual 2.8 Xeons with 4 GB RAM. Most of the
blades that are not in production have a resting load average of 0.00 to
0.08. One particular blade has a resting load average of 0.2 to 1.3.
Even when I shut down just about every service it hovers around 0.3. The
load looks to be coming from softirq. How can I track it further?
irq looks fine, as does iowait and context switching, at least as far as I
can tell.
Here is a snip from top:
