download 1.4.3 if you really had devfee problem its fixed.
Also if devfee got stuck you didn't have those :
[2018-04-17 10:52:16] Pool sent a new job (ID: 606098711433573)
like hitmandn had.
[2018-04-17 10:53:05] Pool difficulty: 1531728
this is an insanely high diff the pool sets, it's a badly setup pool.
Try to set a static diff on the pool if they have that option.

Well pool diff really IS insane, but by looking at this it looks like the devfee fix isn't really perfect.
Can you send me in private the log file for this? If you have.
