I am trying to solve the following error in my apache2 error.log file. I use Debian Jessie 8 up-to-date with apache 2.4.10 from repo.
[Tue May 31 16:35:21.951165 2016] [core:notice] [pid 6926:tid 140394522146688] >AH00052: child pid 6929 exit signal Segmentation fault (11)
This happen when a user connect to the website with an SSL client certificate. Everything works fine except we got this message every time.
To solve this, I try to generate a core dump from apache2. I followed the debian documentation :
chmod 755 /tmp/apache-coredumps/
chown www-data:www-data /tmp/apache-coredumps/
add this to my apache2.conf
Execute the following command :
ulimit -c unlimited /etc/init.d/apache2 restart
Then I reproduce the error, but /tmp/apache-coredumps/ remain empty. User permission seems ok to me.
Any idea ?
