It's SIGKILL too, I think that holds of every unix system I've worked on :-)

My bad, sorry about that.
Philip, PAX is meant to help against buffer overflows and creates a non
executable stack.
I'm not much of a x86 expert, but PAX killed exim with a SIGKILL because
EIP: 00002A42, ESP: 5909799C
I suppose that means EIP is incorrect which is why PAX killed exim.
If it weren't for PAX, I think exim would have received a SEGV

Neither yet, this problem only happened once and I can't reproduce yet.
If I were to guess, I'd be looking at GnuTLS.
If I have further problems, I'll try to switch back to openssl and see how
it goes.
Thanks
