Dev, please look into possible memory leak on windows client and address on next release. After letting it run for several hours memory usage goes up between 1GB to 2GB. This is happening on Windows 7 and Windows 2016.
Try to set maxconnections=10 in conf file.
This did not help, today one of my BTDX MN running on windows VPS was using 3GB of memory.
Getting the same thing on windows 7 machine here - another coin MN doing the same thing - have to remember to restart it daily or it crashes and you have to wait for the grace period again.. not good
