And what does this 503 page content??
I do not know what the issue in hands is but there are couple things to
first test before running into full debug or try to fix issues that
might not exists.

The version upgrade is there for a reason.
I do know why an upgrade might not solve the issues but still if you
have testing environment try to make sure what are the results with the
latest 3.1.X branch which should be 3.1.21 if I am not wrong.

It is very critical for you to test it.
Since squid can run on many OS and many specs your logs are nice but not
helping to understand the whole issue.

There are many bugs that was fixed from the 3.1 list but I have used it
for a very long time.

If you need help installing 3.1.21 or any newer version I can try to
assist you.
Also it can be installed alongside another version.

Best Regards,
Eliezer
