Hi Everybody,

I've had three Butterfly Labs ASICs (Don't laugh!) churning away in a data centre for a few years now... UPS and generator backup power is free for me, so why not! :-)

I'm hosting BFGMiner (currently v5.4.2) on a Debian box and it's been working flawlessly... until this week!

I got an alert that my worker was down. I logged in and see this;

 [2017-05-13 11:14:35] Stratum from pool 0 detected new block


The ASICs are being detected... but it looks like they aren't hashing.   I went on site and hooked an ASIC up to my Win7 Laptop and the actual ASIC hardware is working fine.  The power supply for the ASICs is working fine too.  The Linux machine has been stable, but I rebooted just the same... same result.

Has anyone else seen this happening recently?

maybe try one of the other slush pool domains or just go to stratum.slushpool and let it work it out, seems strange that pools hiding stuff from you and its the only thing that looks odd, maybe try cgminer if that doesn't work and see if bfgminers gone bad somewhere.

P.S im still running the 5GHs BFL miners Cheesy so i dont laugh
