Hi,

I switched our main server from rh9 to sl4 and I now have some
severe performance problems. Whenever spamassassin runs the
whole system gets unusable. Using top shows a load of 5, however,
there is no process using cpu time, spamd is in an uninterruptible
sleep (D+) and the only visible percentage in the Cpu(s) line
of top is a value between 60-90% for "wa" (what is "wa" btw?).
I tried to turn HT off and boot the up kernel, but to no avail.

Any ideas our suggestins?

Thanks,

Gerald
