TYPO3 Core

Environment: Windows 2003 server, Apache 2.2.4, php 5.2.1 (problem was the same with 5.2.2), MySQL 5.0.27.

This error is fatal and occurs only while working in BE. It seems to
occur whenever a change is made. This could be uploading images, moving an element, writing inside an element, or simply clicking on an extension.

I can see no consistency in the errors, other than the above, but
then I do not have a thorough knowledge of the code behind.

Tried to downgrade PHP version (to 5.2.1), without a change. This error seems to lock up the apache server, and after restarting Apache service everything is fine (until next time) , MySQL seems unaffected and does not need restarting.

I have several sites running on this server, some of which were moved from a temporary WAMP installation. (With Typo3 version 4.0)
The error did not occur on that installation, but now occurs for moved
sites as well as new ones.

See additional information for error-extracts.
