After adding PostgreSQL module to an Apache webserver, the load on the machine went up to 20. There was no PostgreSQL code invoved, just pgsql.so was activated in php.ini. Here is the backtrace of a runaway process:

I forgot to say that php is compiled as dso with apache 1.3.19. I have tried to compile postgresql extension both as php dso and to compile it into the php module, with the same result.

Please try the latest RC of PHP 4.0.6:

http://www.php.net/~andi/php-4.0.6RC4.tar.gz

I believe this is already fixed..

It has indeed been fixed. 4.0.6RC4 runs fine.
