Multiple errors in logs for statistics plugin

[macin]

Hi,
Not sure when it started, but it's been like this for while now, the statistics plugin is generating a lot of following error logs, for every page view. This is on Kaos 6a...
Any hints as to what coudl be causing this? I have reinstalled the plugin but that did not help.
