     24 heartbeat[17482]: 2007/11/29_07:12:41 info: Status update for  
node drbd01.test.spammatters.local: status up
     25 heartbeat[17482]: 2007/11/29_07:13:45 info: all clients are  
now paused

line 25 is sure to be part of the problem, but also I don't see any  
evidence that heartbeat even tried to start the crm processes.

this is also interesting...

I wonder if the fact that there are two IPs on eth0 could have been  
causing problems.

Oh, and the reason crm_mon was taking so long is related to your  
choice of deadtime which was quite high.
