why does BFG hashrate die off after a while?

[frankenmint]

It should be running at 23 GH but instead it looks like this:



It will start and work fine for maybe 90 minutes but then it dies off and all the erupters turn back on but this is my screen.  Any suggestions would be highly appreciated.

Did it do this eversince with this particular mining setup or onl since an update to BFG or the miners?

My first guess would be a problem regarding the drivers or windows handling so many USB devices.

Try setting the display options of BFG to be more verbose and enable logging so that BFg tells ou more about what's going on that could help you get to the ground of it.

never worked right with windows so I moved to ubuntu - it was okay for a little while but I wanted to consolidate it with my scrypt rig so now I have this version of bfgminer running in the background - everything boots up and runs fine for maybe 40-70 minutes then it dies off.  doesnt give a communication error or driver error it just says pool  stratum pool requests work update

Hmm ok I am out of ideas then. Haven't done stuff on linux in years so I am kind of out of the loop as far as that goes. If BFGMiner doesn't send any errors my next very wild guesses would be that something's wrong with the hardware setup: For instance is the USB Hub's power supply sufficient to run that many miners? Do the sticks get too hot?

I guess you'll have to go through a lot of trial and error unless someone in the forums experienced similar problems and has a solution for you.

Sorry.

I hope you can get help and get it running.

It's probably your USB hub. Looks like the USB miners all fail at the same time and stop mining. I'm pretty sure your first hashrate is frozen. The second is usually more accurate, and 3rd one is actual hashrate based on shares submitted.
