Hi Matthias, Looks like someone else is having problems with asnbl-helper.py with CU 172. They have raised a bug on it. Not sure if it is the same as what you are experiencing as the symptoms are different but they solve it by disabling all anomaly detection.

Worth a look-see to check if it is related to your problem or not.

Regards,

Adolf.

Hi,

sorry, but...

With Core 171 I ran 'squid 5.7' with the options "Deny access to destinations hosted on fast flux setup" and "Deny access to destinations hosted on selectively announced networks" both ticked (activated). No problems.

With Core 172, I found that the 'squid-asnbl-helper.py'-script is having problems with specific urls - it logs a 'traceback' and the helper exits.

Below is an excerpt from '/var/log/squid/cache.log':

Can anyone confirm? And if yes - should I open a bug report?

Best, Matthias
