I've had to deal with the RMI GC issue before. There are properties you can set to have the GCs occur less often/never so you can allow explicit gc for things like DBB memory. I also think it's longer than 30 seconds by default?

This is where I last had to tackle it https://issues.voltdb.com/browse/ENG-5856

We actually don't want to enable explicit GC as it has valid uses for reclaiming direct byte buffers.
