Added to FAQ because I got same question several times:
- EthMan loses rigs with 12 GPUs.
Sometimes systems with 12 GPUs and low-end CPU become slow for remote access, you can see problems with EthMan and other remote management software.
My ASRock H110 Pro BTC+ 13 RX 580 build has a Core i3 6100 CPU. ETHman is constantly losing it's connection. It was working fine until about 2 months ago. TeamViewer also works flawlessly.
In my tests I have problems with RDC, sometimes I cannot connect to this system. Attempts to understand the reason show that server socket does not accept incoming connections sometimes. For me it looks like lack of system resources. If I remove a couple of GPUs - everything is fine.
