Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.


I'm not sure if this can be caused by drbd but I don't know why this happened.

The primary node failed and watching the logs I see in /var/log/kern.log:

I've read some posts and seems like 2.6 probably still has bugs deep under the 
surface that only pop up in certain real world situations. (¿?)
Doing some googling showed some indications that NAT has some bugs (¿?)

Please any help would be very apreciated.
Best regards, Andrés.
