These packages might be some help with that:

There isn't any clear ccause, so if you really want to go that way it
starts with configuring "debug_options ALL,9" to log all debug
information your Squid can produce. Once that is running you will need
to preproduce the problem. Note that you will have to capture the
entirety of one of those multiple-hour long transactions.

This will result in a rather large cache.log which will then have to be
searched through to find the transaction TCP connection details. Which
will show the FD number(s) being used by it.

Filtering the log on that "FD n" will give you a trace of what is being
done on the connection and the timing of those things - hopefully giving
a hint as to where to look for more details.

Good luck.
