We are trying to run a cluster with a CPU load of appr. 40%. The test
application uses CKPT and EVT.
What happens is that the active controller logs that it has missed heartbeats
with other nodes in the cluster. When it misses the heartbeat with the
standby controller, it orders it to reboot.
The heartbeat settings in BOM.xml are default as delivered in OpenSAF:
<sndHbInt>1000</sndHbInt>
<rcvHbInt>3000</rcvHbInt>
Irrespective of this configuration values, I thought the system was designed
with real time threads for managing critical protocols?
And it seems to be:

The process load on the active looks something like:

1398 root 23 4 52468 2716 2020 S 0 0.1 0:04.49 ncs_cpnd
Could there some error in the AVD-AVD/AVND heartbeat design?
In the NCS-AVSV-MIB I see other default values for heartbeats, 300ms resp
2000ms.
