That combination (or, to be more precise, its implication) is possible
but relatively unlikely in your specific case -- when GBs are leaked,
there is usually something tracked related to those GBs. Please note
that what Squid _tracks_ may not amount to GBs of RAM! For example,
Squid can track a tiny object that is included in every large untracked
leaked object.

A frequent leak often manifests itself in mgr:mem snapshots as a nearly
always increasing counter of alive associated objects. If you take one
snapshot every 30 minutes or so, then you may be able to identify
suspects by comparing same-object alive counters across 5-10 snapshots.
Sorry, I do not have the time to do that for the snapshots you have
shared (and you probably need a different collection of snapshots to
make this search more productive).
