[squid-users] [External] Re: Cache_peer breaks Squid 5.5

[HENDERSON, GAVEN L RTX]

assertion failed: peer_digest.cc:419: "EX"

Found this:  https://access.redhat.com/solutions/7048529

Any thoughts on how to fix this on Rocky 9?

> Sorry if this has already been answered.  I couldn't find anything online regarding the problem I am experiencing.  I have a Squid server acting as a proxy relay.  It listens on two ports and, depending on which port a request comes in, the request is forwarded to a specific upstream proxy.  Everything was working prior to the 5.5 update.  Now, Squid starts but crashes a few seconds later.  I have traced it down to the cache_peer directives.  If I comment them out, the service is stable.  I have also tried the stock configuration with only the cache_peer directive added and it still crashes so I don't think the problem is being triggered by some other part of my configuration.  I'm not seeing anything particularly helpful in the messages log:

What do you see in Squid's cache.log? I would expect a message about Squid hitting an assertion or detecting another catastrophic problem before crashing. If there is nothing in cache.log, consider (enabling core dumps in your OS configuration and) getting a backtrace from the crashed Squid process.
