Does anyone else have this problem? I have to restart that computer and mining rig about once a day. More than half will err out over 12 hours. They can't recover by themselves?
O.S.: Ubuntu Server 12.04 mining program: bfgminer 3.3.0
$sudo ~/bfgminer/bfgminer -o stratum+tcp://stratum.bitcoin.cz:3333 -u MYWORKER -p MYPASS -S all
ctrl-B, ctrl-D close terminal session
Nothing else is plugged into a USB port. It's one of the simplest setups I can think to make. Block erupters are less than a month old. Block erupters have all the current they'd want at 5V (external power supply and their current demand doesn't get anywhere near the limit of the p.s.)
I'll try to come back as soon as I can find any specific error messages.
Should I not keep the mining executable in my home directory?
