Spamd using 100% CPU, even after reboot

[Christopher Martin <ch...@ebit.com.au>]

I have a dual P3 server I am hoping to run as our main spam filtering
machine. I am satisfied the spam is being caught, I am just worried whether
it can deal with the load as the machine idles with one CPU fully utilised.

Here are some system details:

antispam02# uname -a
FreeBSD antispam02.ebit.com.au 6.1-RELEASE-p3 FreeBSD 6.1-RELEASE-p3 #0: Fri

antispam02# /usr/local/bin/spamd --version

  with SSL support (IO::Socket::SSL 0.97)

There is a recurring error in maillog:

Aug  4 12:03:25 antispam02 spamd[625]: spamd: still running as root: user
not specified with -u, not found, or set to root, falling back to nobody at
/usr/local/bin/spamd line 1145, <GEN598> line 4.


Is that related? Any ideas or suggestions?
