children are killing my server

[mailscanner at berger.nl]

OK,

As some of you guys adviced me earlier, I installed MailWatch on my server (freebsd 6.1). Well, that is a nice package, thanks for that!!
I have only a small problem. I installed it earlier today and it seemed to work fine. I had some problems with the change between linux and Freebsd but I managed to make it work. After it worked great for about 3 hours the messages stopped appearing and after a few more time the server  got loaded more and more. I checked and I saw that MailScanner spawned 70 children (MailScanner.conf says max=5). They all spawned at different times in "ps". There was also no "MailWatch SQL" running anymore, even after I killed all child processes and restarted" I finally removed MailWatc.pm and SQLBlackWhiteList.pm from the /usr/local/lib/MailScanner/MailScanner/CustomFunctions/ dir and after that MailScanner worked fine again.

Does anybody have any idea what is causing this? I know it's a bit off-topic, but I think, maybe one of you guys is using MailWatch with Freebsd too.

Thanks,

Roger
