The memory climbed to consuming 50 GB of RAM



my release 0.6.1 node (not a pool) on Ubuntu 16 using GNU binary also suffered from growing memory utilization (~10GB RAM) after 10-12 hours
Mine also killed after using 5GB of memory, currently testing with 10GB with limit of 12GB

Still an issue on version 0.6.3
There is now version 0.6.5 with one identifed cause of runaway resource hogging fixed. Please retry with the new version.
One possible source for runaway RAM consumption is unbounded message queues that are currently used to respond to client requests. Fixing this requires a rewrite of the "client" serving task.
Memory consumption issue has been addressed since 0.7.0-rc3
