I checked all my old logs and this message appears 3 or 4 times per day,
usually between midnight and 3:00 AM, which is when the backups run. The
longest delay was 15 seconds, which seems to have occurred only once.
There were a couple of delays in the 10 second range, and then all the
rest were 5 seconds or less. My deadtime configuration is 30 seconds. 

1. Do you think I have anything to worry about?

2. Why would backups cause so much load that heartbeat can't update?
These are 8-core 2.6GHz machines with 32GB RAM and 6x 15K SAS drives in
a RAID 5 array.
