Hi All,
I have several RaQ3 and RaQ4 servers. On one particular server, I get a
consistently high loadaverage of above 2.00. I cannot figure out where the
load is coming from. When I view top, I do not see any thing outstanding.
PSTREE shows a normal, average amount of processes. CPU usage is low, and
memory swap is low. Both are indicators of good performance.. Yet, the
load average stays consistently above 2.00.
I shut down the ASP engine and tested the load average, but that did not
make a difference. I then restarted ASP and then shut down HTTPD and
tested the load average. Still above 2.00. I have seen MySQL processes
increase the load average on a server, but pstree shows only a few MySQL
processes running -- not enough to account for this high average. Also,
sendmail processes seem light and this doesn't seem to account for the high
load average.
I have posted a copy of TOP and PSTREE below. If anyone has an idea why the
load average is consistenly above 2.00 on this server, please let me know.
My other RaQs are configured exactly the same as this one, yet the load
average is under 0.25 on average.
Thanks,
Bill
