Hi, we have been happily running dspam 3.8.0 ever since it was released
without problems. Now, today all of a sudden, I am getting either a
segmentation fault, or a floating point exception. It will run for a few
(between 1 and 5) minutes and then crash. Has anyone come across this
before? We use postfix with this. I am going to attach a slightly cut
down stack trace to see if anyone can help debug this problem:
