Memory Limits

[pogzie]

Possible to add memory limits to the parameters? Im getting OOMs when using Docker. Possibly due to https://github.com/dotnet/coreclr/issues/18044

I've tried disabling swap but still getting OOMed. Wondering if approaching via code would be beneficial.

Try using 0.3.6 and beyond. It seriously reduces the menory usage. Setting - - threads should improve it further

my last configuration was 1 CPU and 1Gb ram. still OOMing. my minecraft configuration is 0.5 CPU and 1gb ram so I dont think that setting more than 1gb for a map renderer doesnt make much sense, or rather counter productive.

i've already halved the default and set 8 threads than the default 16. i havent tried 0.3.6, i will do so today.

Yeah unfortunately it still cant render with 1 CPU and 1GB memory allocation. Still OOMing.

I've set the thread lower from the default 16 to 8. I will lower even more and see.

Changed down to 4 threads still OOMing.

I'll try to add some flags to force Garbage Collection and further reduce the memory footprint. Maybe that will help.
