[Tue Jan 03 20:49:28.989355 2017] [core:notice] [pid 25890] AH00060: seg fault or similar nasty error detected in the parent process

and apache main process crashed. Apache 2.4.23 not affected. Build with default configure.apache file. OS: Latest Centos 7 x64.

Anyone have this issue?

Some config info about settings versions and customizing parts could help for support.

Tried httpd- restart?

Wen did the updates takes place and where they from apache 2.4.23 to 2.4.25 ?

I'm try to reproduce and found than problem into http2 module. By default apache build detected nghttp2 library and enable http2_module:

http2_module contain bug: https://bz.apache.org/bugzilla/show_bug.cgi?id=60510

For resolving this issue need to add "--disable-http2" to configure.apache and rebuild apache. I hope this info help someones.
