@MagicSmoker ... whatever you say.
@realbminer: I found a quirk.
[FATA] [2018-02-07T15:12:32+02:00] Irrecoverable errors from watchdog: Client hasn't received Accepted Shares for 5 minutes
When using a single card with high enough difficulty it's possible that a share is not found in a long time. It seems this happens when the pool doesn't send a new share within 5 minutes, but that's not an error, the miner shouldn't disconnect. Could you add an option to tune this time window please? Also, "Client hasn't received Accepted Shares" doesn't sound right ... do you mean "Client hasn't received new jobs from the pool" ?
