Description rustamabd 2017-01-08 11:02:09 UTC
After upgrading apache24 to 2.4.25_1, getting lots of:

kernel: pid 72245 (httpd), uid 80: exited on signal 11 (core dumped)

Nothing else has changed on the system.

FreeBSD 10.3-r15 amd64

Upgraded to php70, the issue remains.
Rolled back to apache24-2.4.23_1, the issue is gone.

Pse contact me for the core files.

Looks like the issue is in mod_proxy_ajp.

Maybe this patch will resolve it:

Also seems to not happen in 11.0, only in 10.3.
Comment 3 Olli Hauer freebsd_committer 2017-02-22 20:39:56 UTC
Not sure if this is an mod_proxy_ajp issue.
In prod. I run only 10.3(amd64) frontend servers with mod_proxy_ajp and haven't seen any instability even on systems with 20 - 50 hits/s.
But I have to admit none of my frontend servers running PHP ...

If I interpret the change and the changelog correct it fixes only an issue if loglevel is set to trace2

The patch did not resolve it indeed, but all is fine in 11.0. So putting this one to rest, hopefully will never occur again.
