Ok - but is it going to be patched only in the v6 version? I've just grabbed squid-5.2-20211028-r74f073ecd and (for example) ReadWriteLock.cc does not look like in the patch (no finalizeExclusive() etc.) Anyway - in the morning I run debug with 20,9 to see:

Your Squid is buggy, and those bugs essentially cause queue overflows. The assertion itself is known as Bug 5134: https://bugs.squid-cache.org/show_bug.cgi?id=5134 That bug has a speculative fix (master/v6 commit 5210df4). Please try it if you can.
