Bug#867565: seg fault apache2.

[Przemek Jagielski <przemek@jagielski.ovh>]

Hello,

I've the same problem with my installation. Some information about stack:

Server version: Apache/2.4.25 (Debian)
Server built:   2018-03-31T08:47:16

Kernel version: 4.16.8
OS: Debian 9.4
PHP 5.6.36-1+0~20180505045928.13+stretch~1.gbp9b5cab (cli)
Copyright (c) 1997-2016 The PHP Group
Zend Engine v2.6.0, Copyright (c) 1998-2016 Zend Technologies
    with Zend OPcache v7.0.6-dev, Copyright (c) 1999-2016, by Zend
Technologies
For my website, I use php5.6-fpm and reverse proxy (nginx -> apache2). 

In kern.log i see this error:

Jun 17 13:54:27 alibox kernel: apache2[14997]: segfault at 7fde538287a0
ip 00007fde538287a0 sp 00007ffdfa05e588 error 14 in
libexpat.so.1.6.2[7fde55891000+27000]

This error I've when one of my website have crash. This page probably
wrote on PHP 5.3. I must restart apache2 so that the website starts to
function normally. When I restart apache2 again, when site working ok, i
haven't any error. Can you tell me, where i must search problem? Is a
problem, can be a my kernel config?
