[Bug 63870] New: Core dump
https://bz.apache.org/bugzilla/show_bug.cgi?id=63870

Bug ID: 63870
Summary: Core dump
Product: Apache httpd-2
Version: 2.4.18
Hardware: PC
OS: Linux
Status: NEW
Severity: major
Priority: P2
Component: mod_http2
Assignee: bugs@httpd.apache.org
Reporter: eldy@destailleur.fr
Target Milestone: ---

I use the apache server packaged with Ubuntu 16.04 (the up to date version of
ubuntu distribution), with 2 thousand of virtual hosts.

I need to add / remove frequently new virtual hosts and use apache2 reload
every hour. Everything works correctly, performance are goods. However, after 5
to 12 days, apache2 hangs with a coredump making all my customers offline.

I need to kill it and restart it to have it working correctly again (of course
I scripted this to be able to do this automatically to reduce the outage, but
it is still annoying and i would like to help to have this fixed definitely in
official version).

This problem is very annoying for my business (I am an Open Source developer
- author of AWStats log analyzer - and the project leader of Dolibarr ERP CRM
project that is the project that I host as a Saas service via the offer
DoliCloud).

The problem can be reproduced, but is is long because i need to wait around 1
week, to have the trouble fixed. But it does not matter if it takes time to fix
this. What is important is to find how we can avoid this coredump.

I have several similar platforms, and all platforms have the trouble.

I have technical knowledge, so I can make system actions if more information
are required, but I have no knowledge in Apache and C coding and i am not able
to analyze a core dump (but i can provide it). Because this bug is important
for me, i would like to found or hire an Apache developer that can help me to
solve this trouble. However I need help to tell me what I can/must do to
progress in finding a solution to this bug.

This is the following packages that are enabled:

access_compat actions alias auth_basic authn_core authn_file authz_core
authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock
deflate dir dump_io env expires file_cache filter headers include info
log_forensic mime mpm_itk mpm_prefork negotiation php7.0 rewrite setenvif
socache_shmcb ssl status substitute vhost_alias
