[squid-users] After upgrade from squid6.6 to 6.8 we have a lot of ICAP_ERR_OTHER and ICAP_ERR_GONE messages in icap logfiles

[Dieter Bloms]

Hello,

after an upgrade from squid6.6 to squid6.8 on a debian bookworm we have a lot
of messages from type:

ICAP_ERR_GONE/000
ICAP_ERR_OTHER/200
ICAP_ERR_OTHER/408
ICAP_ERR_OTHER/204

and some of our users claim about bad performance and some get "empty
pages". 
Unfortunately it is not deterministic, the page will appear the next
time it is called up. I can't see anything conspicuous in the cache.log.

There was no change to the virus scanner nor any change to the squid
config during the upgrade.

Here the icap spefific config lines from squid:

--snip--

I don't see any changes in the ICAP server area between 6.6 and 6.8
