After looking into Digest::SHA1 and Whiplash.pm I noticed that Whiplash.pm called reset on a Digest::SHA1 object although it just called the hexdigest method which already resets the object upon completion.
It seems calling reset after digest or hexdigest is not only a waste of time, but also the source of the problem.
After commenting out the reset in Whiplash.pm (line 66) :
My system works flawlessly with that line intact. While it might be a waste of time, I doubt it's a source of the problem. I'd take it as some possibly redundant code, but one that is pointing out a problem in your perl libs.
Any chance your copy of Digest::SHA1 is mangled?
mangled no, buggy yes. This is 2.07 packaged by dag wiers for RedHat 8 (latest tar.gz available is 2.10).
I have the same software versions on another system which works without problem as yours. There are 2 diferrences : on the latter one all mail processing is sequential (fetchmail calls procmail which calls spamc), the packagers aren't the same (Digest::SHA1 is already packaged in Fedora Core 2).
I wouldn't expect a reset() method to have this behaviour in any case. The source of the problem might be an obscure bug that is only triggered when 2 forked spamd are processing messages at the same time and 2 Digest::SHA1 objects then conflict when new and reset (which is an alias to new by the way) are called...
