Hey Dan,
The basic rule of thumb in programming lands is script vs compiled code.
Where compiled code can be considered very reliable and in most cases
tested much more then scripts.
I am fearing that there is some race between all sorts of things on
runtime which might lead to this failed test.
There are couple possibilities that can cause the issue you are writing
about.
From the compiled side of the code the main suspect is that the
connection got into a "non usable" state before squid could do something
else.
I have not seen yet the source code for connIsUsable but if you wish I
can try and look at the function\method\call\code source and start a
basic lookup to understand the issue a bit more.
I do not remember if you have opened a bug report yet but I think this
issue needs a bug report.
Take your time to write a brief bug report at:
http://bugs.squid-cache.org/index.cgi
While referring to this thread.
If you are up for the task then maybe you would be able to provide some
more information based on the wiki:

Thanks,
Eliezer

Thanks Eliezer …
We've only ever used `kill` as very last resort when the squid process wouldn’t respond to anything else.
Anyway, I think I missed what led you to think the crash is related to the reply_body_max_size rules' external ACL as opposed to the many others we define?
That would certainly narrow it down a lot further than before.
Cheers
Dan
