[opensuse] apache2 +mod_perl SIGSEGV
Hello All, I've got a difficult one here I'm hoping to enlist some help in figuring out. I dup'd webserver from opensuse 12.3 -> 13.1 and apache2 is throwing SIGSEGV, Segmentation fault. when I attempt to start it with my request-tracker virtualhost enabled. I am installing request-tracker from the openSUSE devel:languages:perl repository, fwiw I'm the package maintainer. I also have another 13.1 test system running this RT packages and it's functioning w/out issue so this has totally stumped me. I've installed the debug repo's and all the needed packages and here is the gdb backtrace output is below. This is very quickly getting out of my depth so I'm hopeful someone can point me in the right direction.

I've compared and synchronized the packages version on the RT server and test system. However there are way more packages on the test server, since it's well a test server ;-), but the required request-tracker, apache, perl stacks are in sync version wise.
Are the outputs of "zypper lr -Up" the same on both systems?
yes, same repos across both systems.
Just to make sure that the working test system and the non-working upgraded system are the same in terms of the software itself.
I spent quite a bit of time doing this earlier with the hopes it was something related to that.

FWIW switching to mod_fcgid from mod_perl has gotten RT working, however I'd still like to know the cause of mod_perl seg faulting. More digging tomorrow! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
