1. Yes, the override is missing the option for a custom pool group. Please add as this is a very necessary option.
2. This problem occurs when you go from one algorithm to another. MSIAfterburnerRemoteServer not on all farms, I get into autoloading ((the system either removes it or just does not start it in autorun.) I think eventually you will find a durable replacement for MSIAfterburner and build control into the body of your program.In the meantime, I ask you to add to the monitoring section the ability to determine how many cards are working and if one of them has shut down to reboot the system!
3. I'll try to solve this problem by setting a low hashrate, thanks.
1. I don't think that would matter. If you make the global setting as the custom pool group then all rigs will use the custom pool group unless you override with Nicehash, Zpool, or MiningPoolHub. The logic still works. Let's say you have 3 rigs, if you only wanted one to use the custom pool group, make the custom pool group the global default. Then on the other two rigs set them to Nicehash or something else in the override.
