VCS nodes keep rebooting
I wonder if you kind people can help me again.
I have a 3 node cluster on Sun x4240 servers, which I have installed VCS v5.0.
There are only about 9 service groups created on them which just have mounts and volumes, so no load on them.
The issue I am seeing is randomly one server in the cluster drops off the network and then I can't access it via the console as root.
This seems to happen for about 15 minutes then it fixes itself, then the other server does the same.
I have noticed that the heart beat connections go first.
My Cluster set up is:
Redhat 5.4 x86
VCS v5.0 RP3
Heartbeats on = eth1 and eth3 (100mb full duplex)
All the servers are built exactly the same with no variation.
has anyone come across this before?
