Apache crashing with this module enabled

[nlmark]

After upgrading from Debian 8.1 to Debian 9.5 and updating Apache to version 2.4.34 Apache crashes on the first page request. When I change 1 config line (comment the line where the module is loaded) it works again.

Linux kernel: 4.9.0-8-amd64 #1 SMP Debian 4.9.110-3+deb9u4 (2018-08-21) x86_64 GNU/Linux

Cf.

• Debian bug #853981 - apache2-bin: mod_http2 together with mod_ruid2 breaks the server
• Debian Bug #866395: libapache2-mod-ruid2: Server crashes (Signal 6 aborted) with mod_ruid2 after jessie->stretch update

Similar problems on Fedora 30. I'm getting the signal 6 aborted and I've pretty much narrowed it down to mod_ruid2 being enabled.

Having the same issue on CentOS 8.

a bit late to the party but it seems to work with mpm_prefork
