I noticed that the rigs would sometimes crash while or shortly after the dev mining period. Maybe the dev mining has a bug. At least it looks a bit strange in the console.
Sometimes they don't crash and just continue the normal mining as in these screenshots. The pool will however show lots of invalid shares during the dev mining period.
Also the cards cool down completely in those two minutes, so I don't think they are doing any dev mining in those two minutes. You might want to check to not lose out your fees.
I used the previous versions of this miner to mine x22i for two months and it didn't have this strange behaviour while mining the dev fee. No hundreds of lines of "oops, stale share" and cards wouldn't cool down at all.
