Not sure if this is directly related, but some time ago I found that
using and emptying large arrays successively resulted in a condition
that looks like a leak, but was later characterized more specifically as
Comment #4 there from Mark Waddingham shows a ramping up of usage that
then levels off, but Comment #7 from Mark Talluto describes a scenario
in which the effect over time can become so severe as to require ending
the LC process.
I'm not familiar enough with the mechanics of fragmentation to offer any
sort of fix for that. As a scripter, I would just like memeory to be
re-released when not in use, but I recognize that putting "just" before
something doesn't necessarily make it easy to accomplish.
