"rec" as in the first characters of the "-k reconfigure" option?

That will only update the running Squid with new config file settings.
Sometimes that can reduce memory, but if the issue is in anyway linked
to the OS report of "maximum _ever_ used" stats for each process, it
will not change a thing - usually make the number higher as Squid must
fork() twice as many helper processes for a reconfigure.

numbers?

config file(s)?

Which resets everything related to memory and starts clean without any
of the OS and fork() related issues such as the one above.

Does the same problem exist with 3.5.27 ?

PS. If you are using ssl-bump at all, make sure you have the Squid-3
workaround of "sslflags=NO_DEFAULT_CA" on every *_port line using
ssl-bump option to prevent openssl allocating vast amounts of useless
memory.
