My IQrouter, which is Archer C7 hardware, is presently running with 73MB free out of 128MB, after nearly 43 days uptime with heavy usage.  It has at least two Cake instances running, on a recent kernel.

I see from the forum logs that kernel 3.18.x is in use there.  That's very old indeed, and I believe there were some fairly big differences in packet memory management since then.  It would be entirely possible for some memory management bug to be introduced by a vendor patch, for example.
