I had php-4.0.4pl1 on one of my Solaris machines (SPARC), and was programing on my personal workstation (Solaris 8 on SPARC both) on PHP-4.0.6-dev (downloaded 2 days after the branch changed from 5 to 6) and PHP worked great with apache.

When I had to pass the programs I had on my workstation, I said, lets update PHP to the 4.0.5 version, so there are no problems.

The problems appeared. When I started entering pages on the server where there php scripts the load started growing. These are some outputs that I have after executing these scripts:

This also happened with a page that only has the phpinfo() function.
