Package: apache2-mpm-event Version: 2.4.10-10+deb8u10 Severity: important Tags: upstream
i have a slightly off-the-beaten-track setup on a live-running i386 (not amd64) server which has (had) apache-mpm-event activated using the standard debian configuration for that module. there was (is) absolutely NO threading modules enabled or in use with the exception of google's mod_pagespeed, where the developers inform me that they do regular testing of mod_pagespeed in both the mpm-event and mpm-worker configuration the modules utilised for the main web serving are mod-fcgid (WSGI) and standard CGI-bin for running PGP (not the normal way to do it but it works very well with mpm_worker and mpm_event). the FCGI application is a python2.7 WSGI web service NOT USING ANY FRAMEWORK. it uses absolutely standard python 2.7 modules that come *with* python, such as the cgi module and other standard HTML-parsing and processing modules, where absolutely no use of threading is made whatsover. mysql access is performed with python-mysqldb, and, again, does not use any threading of any kind. unfortunately it is not... convenient... to do experimentation on the live server. this is more of an "informational" report that "Something Bad Happened" - apache2 segfaulted and left the customer completely without service... twice.... and switching off apache2-mpm-event and going back to apache2-mpm-prefork "solved" the problem. it's also worth noting that absolutely no problems whatsoever have been noted with prefork. stable as a rock, both before mod_pagespeed was deployed and after. -- System Information: Debian Release: 8.1 APT prefers testing APT policy: (500, 'testing'), (500, 'stable'), (500, 'oldstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.11.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_GB.UTF-8, LC_CTYPE=en_GB.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages apache2-mpm-event depends on: ii apache2 2.4.10-10+deb8u10 apache2-mpm-event recommends no packages. apache2-mpm-event suggests no packages. -- no debconf information
