i have also pool switching and pool problems
2 devices and on one it says pool alive (and mining on this pool) and the second device said dead...
also on startup it mostly select pool 2.... and it stys on this pool and dont try to switch back to pool0 or 1(in stats it shows its alive!)
yesterday i had no active pool and a chain errors too look attachment
in this picture it shows first 2 pools are alive and the 3th is death (but the other device was working on it!) and i have seen there was no pool active (first 2 where aive!) and not mining and it shows the chain errors after few minutes....

also one problem is sometimes i have neyrly 0 hw error and after restart (same ssettings nothing changed only restart..) i got tonns of hw errors...
has anyone the same problem?
