Though it says 0 errors, what does the "invalid number..." signify?

I guess that this message is caused by your default sleep
implementation.

Could you type 'sleep 0.1' and then 'sleep 1' in your console on the
target system?
Is the "invalid number" not present with the second case?

Only with first case (sleep 0.1) I get the "invalid number" message.
sleep 1 seems to be OK.
