Hey there,

Unfortunately at this time, this setting wouldn't be something that can be changed.

big problem

I've created a ticket to triage this issue and will update you when I have more information, but for now this wouldnt be possible to change, please look for tweaks you could make to the software itself so it wouldn't need a high vm.max_map_count value.

Hello,

This topic came up again and i've since worked on a solution.
