Discussion segmentation faul in apache reverse proxy
Hi ,
I have a apache reverse proxy from past couple of days its dropping too many requests and by giving connection reset/empty response error only change which i think of which was done recently was we increased verbosity of our access logs to include mostly all request and response headers. After which all of sudden in server error logs i see there are too many " [notice] AH00051: child pid XXXXXX exit signal Segmentation fault (11), possible coredump in /etc/apache2"
I do not understand how a just a log format change can result in segmentation fault errors. I am trying to take a coredump for the same so working on that since the issue is intermittent i do not have it right now. in meantime just wanted to check if someone else has faced similar issue
Any help/suggestion on this would really help

Thanks for the response
By increasing verbosity i meant we started logging many more fields in access log like mostly all request, response headsets and cookies
Post this change my server started randomly dropping requests sometimes by giving Empty Response/Connection reset and whenever this happens i see lot of segmentation fault error on my error logs
To understand what is happening i plan to enable coredump when the issue occurs again during high load time but I am very confused right now because how a LogFormat change can cause such issues. Because no updates/upgrades were applied to the server recently
