Subject Re: how long to wait for action (waiting for bootstrap token)
Date Wed, 15 Sep 2010 15:10:10 GMT
Strange, it needed a few attempts before they actuallyfound each other with several UP and
downs
Now the node started bootstrapping, finally. It should be noted in the docs that this is a
blocker. One expects that they pick up after finding each other again as the docs say be patient.
