apache Segmentation Fault

[buggolo]

Hi to everyone,
after a software upgrade on my "Ubuntu 8.10 Server" that included PHP and Mysql packages i have a very very great number of errors like this in my /var/log/apache2/error.log.

Does anyone has an idea about this problem? By reading log file, it seems that this happens just after the software upgrade....

I am seeing similar log messages. I'm not sure when they started or what causes them.

I have the same problem.

After installing Apache, I got the "It works!" message when visiting http://localhost.

If I install mod_wsgi (libapache2-mod-wsgi) or fast-cgi (libapache2-mod-fcgid), the page doesn't display and the error log get filled by these segment-fault error message:

[Sat Mar 14 13:58:27 2009] [notice] child pid ##### exit signal Segmentation fault (11)

I am using Ubuntu 8.04 (on a VMware Workstation 6.5.1 virtual server). I got the same problem with Debian 5 on EC2.

any ideas? i just upgraded from feisty to gutsy and then from gutsy to hardy. Now my apache is giving me segmentation faults whenever i access a page

More than likely Apache is trying to load a library that isnt there after the upgrade, i would recommend reinstalling Apache.

Took me a few hours to track this down, but here is what fixed if for me ... turns out the default setting of epoll=128 limits you to 128 apaches in Intrepid

echo "fs.epoll.max_user_instances=4092" >> /etc/sysctl.conf
sysctl -p
