Hi Lars -

So here's the strange thing.  After my last cry for help things seemed 
to right themselves.   All I did was turn off heartbeat altogether.   
and managed drbd by hand.  trying my test from the secondary(made 
primary) etc.   It all seemed to work.  Then I  rebooted to a clean 
state on both machines (the only thing changed was that I turned off 
auto-failback in heartbeat).  Everything still worked!   Strange.   I'm 
perplexed.  I'm assuming that all of this was simply circumstantial and 
that it would have worked anyway, but the strange thing is that I was 
able to repeat the problem I had 3 times.. before all of the sudden it 
started working fine...  mysterious.

I rebuilt drbd with your patch anyway though and am trying my tests 
again(so far no scary errors!) :-)

So this begs the question of why it would have happened in the first 
place?   Was I having some weird memory usage that I can't replicate 
now?  Have you seen this problem before?

Thanks so much for everything btw!

Cheers,
Tim
