23.7 Legacy Series / Squid 6.5 keeps crashing when Parent Proxy is on

« on: November 21, 2023, 04:21:59 am »

Hi all,

I recently updated OPNsense to 23.7.8_1, and found that Squid kept crashing when Parent Proxy is on. After I turned of the Parent Proxy, Squid stopped crashing.

I have set up Transparent proxy, SSL inspection, Log SNI information only, Access Control List/Allowed Subnets, Parent Proxy(pointing to a local http proxy server). This config was working on old version of Squid(5.9).

Here is the logs(Cache Log) when Parent Proxy is on before crash:
