Mousehouse...check out the bottom graph here
https://siastats.info/mining_pools.htmlI got the same huge number of errors last night, it correlates
with the pool and whole systems hashrate falling off a cliff
This has happened to me a couple of times now and also
seems to be at the same time as the other dips in network hashrates
Last night was by far the worse, since this event my miner has run
again perfectly for around 8 hours, with few errors
I have always had my miner running at 400 to 500 since new,
Neo-geo, did you get this issue last night or were you somehow immune
cheers
Sorry for repost, but we have so many A3 threads (hey mods! unify threads!

)
For those interested in A3s (all of them) dropping hashrate at the same time, in all pools, there is a channel discussing that in the unofficial sia discord (
https://discord.gg/EVn3HPK). So far the theory is that is caused by some blocks, probably a bug in the A3s. The issue lasts until a block is found and they go back to normal. Boards restart when mining these problematic blocks and fans stay at 100% after that... Very weird.
Very plausible indeed. I can see this in my own hash graph at SiaMining as well. I managed to restart the hashboard that stopped working altogether, but strangeness all around.
