Random segmentation fault
Hello,
I have exactly the same issue that here https://mail-archives.apache.org/mod_mbox/perl-modperl/201509.mbox/%3CCAC5eUSu85CoiT0MkQvwvxjfrhJcn13DqJfV=EgFuXvwsWYrXLg@mail.gmail.com%3E
Same OS, Debian Jessie, and no problem at all with same configuration and Debian wheezy -> apache2 2.2.22 and mod_perl 2.0.7
After a while apache2 crashes with "Out of memory" but the complete system are using less than 15% of ram ...

I ended up falling back to the previous Debian release. I'm planning to try
again in Debian 9.
