Ok, so did some research and what I'm finding is that:

If I set sslflags=NO_DEFAULT_CA for http_port and disable both mem and
disk cache then memory is very stable.  It goes up for a little bit
and then pretty much stabilizes (it actually goes up and down a
little, but doesn't seem to be growing or trending up).

I then enabled memory cache (10GB worth) and ran that for a while.  As
the cache filled, memory usage obviously went up.  Once the cache
filled, memory usage continued to increase, but at a slower rate.
Unlike before, it doesn't seem to stabilize.  I'm seeing memory usage
increase in top (virtual, resident & shared) as well as in mgr:info's
"Total accounted" line.  It's not growing as fast before when I didn't
have the sslflags option, but it is growing.

What other information would be useful to debug this?


Since the accounted is growing the mgr:mem report should contain some clues. It is a TSV spreadsheet of memory allocations, you may need a few snapshots of it to see trends.
