[squid-users] FATAL: assertion failed: peer_digest.cc:399: "fetch->pd && receivedData.data"

[Brendan Kearney]

list members,

i am running squid 6.5 on fedora 38, and have found this issue when 
running "cache sharing" (or cache_peer siblings) between my 3 squid 
instances.  a couple weeks ago, this was happening and an update seems 
to have fixed the majority of issues.  when i ran into the issue, i 
could disable cache_peer siblings and restart the instances that 
failed.  the recent update seemed to have addressed the problem, but i 
turned on ssl bump for a subset of traffic and the issue returned.

when i have all 3 proxies started, all of them will work for a period of 
time, then slowly all but one of the proxies will die. the last standing 
proxy does not go down because all other cache_peer siblings are 
offline, and the logic causing the failure does not execute.

this was a larger issue before the recent patch/update, but is still an 
issue when performing ssl bumping on traffic.  is there something i can 
provide in the way of logs or diagnostics to help identify the issue?

thanks,

brendan
