Hoi,

I upgraded 1st node and here are the logs
https://dl.dropboxusercontent.com/u/1773878/pacemaker-issue/node1.debuglog
https://dl.dropboxusercontent.com/u/1773878/pacemaker-issue/node2.debuglog

Enabling tracing on the mentioned functions didn't give at least to me any
more information.

Cheers,
Pavlos
