Memory leak in 2.3.16?

Memory usage of a maxscale instance stayed low for a little less than 24 hours, then went up to about 4GB quickly within a span of ~30 minutes:

This was originally reported against 2.3.9, which had some known leaks, but still seems to happen after upgrade to 2.3.16 (graphs are from 2.3.9)
