FWIW, this behavior is a Squid bug: Since a peer has several
traffic-affecting properties besides its address, the connection
selection logic must obey peer selection choices, even if all peers have
the same addresses. The same underlying problem might result in the
wrong peer used after a hot reconfiguration, even if all peers have
distinct addresses.

Please report this bug to Squid bugzilla. This bug does not have a
trivial fix but hopefully somebody will volunteer to provide or sponsor one.


Thank you,

Alex.
P.S. Workarounds and workload cleanup suggested by Amos is good advice.
I just wanted clearly classify this as a bug (rather than desirable
behavior), so providing or facilitating a quality fix would be welcomed.
