Issue
After upgrading to 1.62 from 1.51a, the log spews periodic memory leak tracking data.
It's unclear if this poses an actual problem for long term server operation: memory utilization doesn't seem to be ballooning after several days. This does cause some server TPS spikes when the reporting happens. And, it's not great to be in a place where things like this periodically fire off.

Thanks for the report - Do you mind checking if this happens on 1.64a?

Sure, I can upgrade the server tonight and run it through the paces. It'll be about 12 hours (I'm on west coast US time and currently at work).

Sounds good, I will be available in 14-15 hours hopefully.

I upgraded to 1.64a, the upgrade went smoothly. This problem did appear once I logged in. I let the server sit for a bit (about 20 minutes) before connecting and once I connected, I started to see periodic leaks. Log of the leak spew here:

I don't know what to make of this to be honest, there's not really any helpful information in the log.

This leak seems to be related to OpenComputers, just in case that may help out

We do have two OpenComputers systems in the base. I can take them down and see if it results in a change. I can also look into the OpenComputers open bugs / version info and see if I discover anything.
