I have a gateway that’s acting up and throwing continuous Sfc Flight Recorder errors related to data pruning. Has anyone experienced this before, or know what the issue might be?

I’ve also seen routine clock drift warnings in this particular gateway, normally around garbage collection events. I figure I can fix that by setting the garbage collector to G1GC and maybe raising the memory?
