History not working any more

Moin!

On my server that suffere a disk overflow the hobbit history is not  working any more. While I do see the events in the event log and in  the hobbit data directory, I can not see the events when using the  history button of the test page. The latest events there always show  the date when the file system overflow happened.

Any ideas how to fix this or how to look further into it?

TIA and so long
-Ralf
