The log seems to indicate that some assertion is failing.
Is this an assertion on the swaplog or my config ?
would it help to purge the swap log
is it possible to restive the  element which violates the assertion

Feel free to ask for additional information

Any Hints are welcome. I am new to squid and inherited this project

Thanks

Jannis
