 Hi Philip,
 
 thank you for responding. I am sorry, the server in question is in a
 production environment, I cannot change the build flags there. But maybe
 the is a chance - I have a backup server with a similar configuration,
 on that machine I can alter the build flags. I am not sure that I can
 reproduce that kind of traffic which causes the seg-fault, but I give it
 a try.
 
 Yes, I agree - I see that problem more on the perl side than on
 mod_perl, but reviewing some dumps I believe the problem always happen
 in "cleanup", after a apache request has been served ... so maybe the
 problem is just in the middle of two chairs.
 
 Cheers
 
  Heiko
