Hi Dan,
 sorry RL getting in the way these weeks.

Two things stand out for me.

Its a bit odd that exteral ACL entries shodul be so high. But your
"normal" report has more allocated than the "leaky" report. So thats
just a sign that your external ACLs are not working very efficiently
(results being fairly unique, so the lookup cache not being much use there).

In the "leaky" report there are 10K concurrent requests still active.
Normal report shows only 1K requests. So up to 10x the state data
storeage is needed by that proxy.

I'm a little suspicious you might be seeing another symptom of the issue
behind what others have been reporting as too many CLOSE_WAIT sockets
staying open with Squid not doing anything for them.
