Apache crashing after upgrade

Good morning,

I've recently upgraded our system from ubuntu 12.04 all the way up to 16.04 (don't ask). Simply put, a few do-release-upgrade cycles followed by an upgrade from custombuild 1.x to 2.x and a complete recompile. Everything seems to work just fine now (spam filtering in exim got even better :) ), except for apache.
I've recompiled it (together with PHP 7.1 and everything else installed by custombuild), done rewrite_confs, but i still get the following errors in /var/log/httpd/error_log when my webserver gets visited:
Code:
[Mon Jan 15 10:06:34.708365 2018] [core:notice] [pid 32735] AH00051: child pid 1159 exit signal Aborted (6), possible coredump in /etc/httpd

and so on. On the browser side, i get an indication that the connection was reset by the server. Nothing else.

Other than that, nothing is logged. I've tried turning on logging for PHP, which initially did error, but i've fixed that by disabling some PHP modules. The apache errors remained as they where.

I seriously hope anyone can help me out here, otherwise i'll be stuck in the dungeons of the :mad:evil debug monster:mad: forever :p .
Thanks in advance!

Check the value assigned for memory_limit in php.ini
memory_limit = ?M

What value do you have?

Memory limit was good. 256M. Thanks for thinking with me though.

After browsing through the forums a bit, i just found the answer myself: it turns out to be an issue with debain/ubuntu's libraries and mod_ruid2, which causes a segfault. Can't believe google didn't bring that up.

Anyway, you can find more about it on this thread: http://forum.directadmin.com/showthread.php?t=55163
