[rt-users] httpd2-prefork segfaulting on SLES11

[Brian Dial]

i'm having problems with running RT 3.8.8 on SLES11.  4/5 times when i try to start apache it segfaults


[16167.712443] httpd2-prefork[24765]: segfault at ba37a3d4 ip b742f3b1 sp bfad70a4 error 4 in libc-2.11.1.so[b7402000+15b000]


when it does start, rt works fine though.  i've had this on several builds i've done as i've been playing with RT.  Its similar to another issue someone had with opensuse 11 (http://www.gossamer-threads.com/lists/rt/users/96624) 

The first build I did, I let make fixdeps do most of the work installing moduls from cpan.  I did another build today where I tried to install as many modules as possible from the sles sdk cd.  results were the same always.

I did a strace httpd2-prefork -X and see this
