I have not had a failure with the original ethminer but I am using the switch -S with this one which the original does not have.
ethminer -G -S coinotron.com:3344 -O username.workername:workerpassword
original line is ethminer.exe --farm-recheck 200 -G -F
http://coinotron.com:3342/username.workername:workerpasswordWhat could be possibly wrong? This happened only after several hours of running.
Also have trouble but sintax "ethminer -G -S coinotron.com:3344 -O username.workername:workerpassword" job unstable.
What parametr -F mean?
P.S Params -G -F not job. Params -G -S job unstable and freeze (stop after some time....)

P.S.S Params -F (Work farming mode:
-F,--farm Put into mining farm mode with the work server at URL (default:
http://127.0.0.1:8545))
