yes it did, I should have checked for that and would have if the wrong

I've had a look whether I could reproduce the issue somehow and there is
a potential crasher if the accesslog entry contained "reqmod:
eduPersonAffiliation:+". Can you confirm whether you have entries like
this in your logdb? There shouldn't be a way to have this kind of entry
generated that I could see but processing one can sometimes cause
a crash like the one you've been seeing.
The following patch should fix an issue where an invalid accesslog entry
of this sort is encountered. It should help you if that is the issue.
