[users at bb.net] strange reconnect bug

[Pierre Tardy]

Hi Greg,

I am not aware of this particular problem.
The worker management code has changed a lot bw 0.9.1 and 0.9.2, so indeed
this is worth an upgrade.

When you mean power cycle, you mean sudo reboot, or a real power cycle?

Do the system eventually recover from the error, or do you have to restart
oot your master as well?

Regards
Pierre
