I don’t know exactly why but last time that I reinstall Ubuntu and Apache2 on my server, I got the message error:

unable to create worker thread

So, I added the following to /etc/apache/httpd.conf

ThreadStackSize 1000000

Then restart apache:

/etc/init.d/apache2 restart

What happened?

This configuration sets the limits the size of threads to 1Mb and creates a much less memory intensive apache.
