I just started using the Z11 2.3 Fuddware on 4 x Z11.
This is the first time I have used any Fuddware.
The firmware works great for around 10 hours.  Then, the machines stay working (as shown in control panel), but LSTime (last share time) keeps increasing as no new shares are submitted to the pool.  This never ends; hours and hours will pass.  Poolside hash rate drops to zero.
A reboot fixes everything.  But very annoying to reboot every 10 hours.
Any idea what the problem is?
Happened on Luxor and Suprnova, the only 2 pools I tried.  Same deal.
Obviously dev fee kicks in once in a while but not for hours and hours.
