[Bug 327306] [NEW] Apache segfaults under load and can't span more than 130 childs

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

I'm in process to configure an apache under ubuntu 8.10 to catch some
serious load. To test the server I run "ab" with -n 100000 -c 10000. I
saw apache childs segfault and was wondering why I never saw more than
about 130 childs....

I then stumbled over this article: https://issues.apache.org/bugzilla/show_bug.cgi?id=46467
which suggests:

echo 1024 >  /proc/sys/fs/epoll/max_user_instances
where 1024 is some value larger than MaxClients, then it works.

Further information:

After applying the setting, my apache spaws the configured 5000 childs
and no longer segfaults
