Apache keeps on crashing during installation

[ruchida]

Serendipity 0.9.1 (or 1.0 beta also) makes Apache crash. Any help would be appreciated. PHP 4.4.1 and MySQL 4.1.12 on Windows XP SP2.

It is not Serendipity that is crashing your Apache, it is PHP.
PHP applications cannot crash Apache, only PHP itself can do that, so this is actually not related to Serendipity...

You cannot use Apache2 with a multithreaded environment and PHP. You need to use the prefork method, this is also documented in most Apache2+PHP install guides. PHP is not thread-safe, and what you are experiencing are the effects of not being thread-safe.
