FWIW I'm not seeing any changes in those Squid versions which relate to
persistent connection or pipeline handling.

There is <https://bugs.squid-cache.org/show_bug.cgi?id=4673> from last
year which still lacks any hints about what might be causing it.


FYI: Details on obtaining backtrace info can be found at
<https://wiki.squid-cache.org/SquidFaq/BugReporting>. This issue though
spans multiple transactions. So we will need a detailed (ALL,9 if
possible) cache.log trace of everything that FD has been used for in
addition to the trace. The trace itself is useful for identifying the
code path and FD value to look at within that log.
