Index servers TcpInputProc error messages

[fuster_j]

I have 2 index servers that is LB and listening to port 9997. Both are getting a lot of this message in splunkd.log:

06-19-2012 10:23:59.920 ERROR TcpInputProc - Error encountered for connection from src=:. Timeout

Is it because the port 9997 is saturated? Do I need more index server to fix the issue? How do I debug it? Or, how can I determine if NIC TCP 9997 is saturated without installing 3rd party tool?

Getting a similiar error : default group property contains invalid group name
