Nevermore 2.3 on ethOS randomly stalls out after switching to dev pool

[Cryptominetech]

I have a 4 rigs that are 13 1060 6gb gpu rigs on ethOS, intensity is 21, core +70 mem -502 power 100watts, Randomly, after 30min to 4 or 5hrs after switching to the dev pool I get stratum connection timeout errors, then it starts reporting block height and difficulty after a few lines over a few minutes then says 'pool switching timeout error' then switches back to my mining pool then just hangs up by continuing to report out block heights and difficulty with a random stratum difficulty line from time to time but never starts hashing again. I have tried multiple settings on core, mem and intensity and the same results. I am unable to get this running stable. I have a 1080ti rig with 2 cards at the moment but same form factor can house 13 gpus and has 2 PSU's, no problems at all. Please, if you have any thoughts on this let me know! Thank you in advance for your time.
