Terk, I have a problem, my reject rate had stabilized at 2-3% below the pool`s reject, them out o the blue they become consistenly higher than the pool's.

this is the second time it happens today
 last time i had to stop all miners, switch to another pool for 10 min and after I got back everything was back to normal

My miners began to receive this reject message: Low difficulty share
 this is really strange
 my internet has been fine, no disconnects whatsoever

prior to the changes my reject rate used to have a pattern but they never became so higher than the pool's for such a long time

Thanks for your effort
