You should consider updating to 4.34 because 4.3{2,3} has a problem
with Received: headers that are missing when the mail is fed to
SpamAssassin.

This has nothing to do with your current problem, afaik, but it is
important because it might cause legit mail to be rejected.

Any real good reason not to use the dynamic module? It's much easier to
use the dynamic module, you can enable / disable it at will, and it
doesn't matter in performance.

Is there anything related to these ID's in the rejectlog and/or paniclog?
I'm not sure what distribution you are using, but spamc/spamd might also
log messages to /var/log/{syslog,messages,mail.log}.

They most probably are. I haven't checked, but I can't think of any
other size to display in such an error message ;)

Tried sending a large message to yourself? Updating exim, spamassassin
and/or sa-exim? Tried running spamc by hand on a very large file?
Try running exim4 in debug mode, strace -f the process, etc, etc. :)
