If you perform 'rndc stop' while memory is growing, does it cause a
crash (due to an assertion failure)?  If so, it means memory leak.

Also, if you have many ACL related settings, try the patch included in
bind-9.5.0/KNOWN-DEFECTS (although I suspect it doesn't help according
to your problem description: 'after a day or two').

I'd also suggest enabling http statistics interface (you'll need
libxml2 for that) and monitoring the 'memory contexts' section.
