[squid-users] Connection reset and assertion failed

[Thomas Dev]

Hi,

currently, we are suffering from aborted downloads while going over
squid. When I look into the ethernet traffic, I can see many TCP-rests
by squid and in close timely relation to those resets I see messages
like:

2022/07/15 12:04:24 kid1| assertion failed: tunnel.cc:1227:
"!waitingForConnectExchange"
    current master transaction: master1178

in cache.log.

Are these tcp-resets related to the failed assertion and can I do
something about it?

Thanks in advance.

Kind regards
Thomas
