TYPO3 V4.5.2
php V5.2.11

To exclude buggy EXT, I have deinstalled successively every EXT. Finally only belog and beuser was installed, and still the Error was logged.

The site was updated from V4.2 to V4.5 before.
On a test-Enviroment (similar to live but slightly different php is V5.3 there) no problems occured. Changing the php Version on Live-Server to 5.3.2 had no effect.

All EXT are updated to latest Version, Exept tt_news (still last 2.4, but no difference if installed or not).

Maybe this is only by accident, but look at the time. 95% of this Messages apear every 10-11 Sec. There is NO cronjob installed and scheduler is not installed, too. No difference if BE user is loged in or not.
