The service is still hanging up. I did a few tests. Small files ~100MB don't affect it. Larger files or multiple connections with smaller (or larger) files stall the connection out. It'll run with good throughput and then slow to zero and sit there. Sometimes it will release in bursts and push through but more often it just stops, requiring a reboot of the cloudberry drive service.

Disabled the cache and turned it off. I'll let it run a bit and see how it goes.
