Are you reloading VCLs in your container? Loaded VCLs contribute to
the memory footprint but that's usually negligible. However we've seen
setups where cron jobs or similar means would schedule reloads on a
regular basis whether or not the VCL actually changed on disk, leading
to thousands of loaded VCL. And that could look like a leak with the
memory footprint gradually increasing.
