Description:
It would be great to have more printouts describing what happens during node/system restart wrt the redo log

From:
2010-01-28 07:45:55 [MgmtSrvr] INFO     -- Node 4: Flushing complete

Until
2010-01-28 09:00:28 [MgmtSrvr] INFO     -- Node 4: Suma: asking node 3 to recreate subscriptions on me

It is impossible to know what happens in the data node (whether it is applying the redo log, doing invalidation etc), if it has to wait for an ongoing LCP to complete etc etc.

How to repeat:
Just crash a node , restart it, try to interpret what happens.

Suggested fix:
Add more info events
