Thanks so much for your kind response, Jamie. It is much appreciated!
Here's the issue which started about 2 or 3 weeks ago.
Updates/upgrades performed about the same time:
OS X 10.4.11 to OS X 10.5.3/10.5.4
SA from 3.1.8 to 3.2.5
cgpav/clamav... went from 0.6x to 0.8x, but it is currently turned off.
CommuniGate Pro 5.2.2 to 5.2.5
Configuration changes:
stopped using the xbl.spamhaus.org blocklists, spam load increased
At first I was concerned when looking that the Activity Viewer (in the
Utilities folder on all Macs) that I could see the issue. The inactive
memory rises to the point that the free memory is a small sliver of
the pie. Apple's knowledgebase indicates that there should not be an
issue with this and indicates this is reused on demand and is really a
cache. I am having my doubts however.
Processing slows and email flows like syrup through a straw at this
point. Seems like spamd processing is taking many minutes. Using the -
L option to turn off DNS checks seems to make no difference.
Reinstituting the server blocklists sees the server load fall. Mail
continues to be delivered as server load increases but the number of
'orpahaned' .tmp files increases. These are fully processed spamed
email ready for submission, but it seems the spamd exceeds the
CommuniGate pro 2 minute limit for a shell call. Stalker Software,
makers of CG Pro, don't support SA so they simply reply that if its
taking that long for SA to process spam, then I should consider their
Mailshell or Cloudmark plugin which can process 20 emails per second.
(Mailshell did a poor job when I used it several years ago, so speed
isn't everything. SA does a much better job at identifying spam I
think.)
I have not ever used sa-compile, but am going to get that installed
this weekend to see if I can bypass the Perl-SA interpretation of
local regex rules (I know it won't compile all the rules though) and
improve performance and help see if this is possibly the source of the
problem.
I understand that this may sound obscure, but believe me, I'm not a
novice and there seems to be a real issue. I've considered even
dropping back to OS 10.4.11, a time-consuming but possibly necessary
step in further identifying this issue.

Yes, Kai, I noticed there were no replies. In fact, I've noticed that
for the most part many of the folks on this list try to be as
unhelpful as possible to new posters on the list. Almost like there
is
challenge over who can be the quickest on either a rude comment or
put-
down.
Wow... Personally, I find this list to be one of the most helpful,
least-rude lists around... I've only been here about 5 years too.
I missed the prior emails on this thread, but if you can detail more
about your setup perhaps someone with the same setup (issues or not?)
may contact you ...
To be honest, it's kind of a "bad time" for many admins - DNS servers
around the world need to be patched ASAP, and there are a LOT of them
out there that are vulnerable to the latest (real, and very bad!)
cache-poisoning exploit. If you run a DNS server, and have not yet
tested/patched it, *please* see
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2008-1447 asap.
