NW6/SP5/NWCS 1.6.4,

I am wondering if my node fails because the LAN becomes busy due to
network broadcasts. There are no abends and no specific time of day
when the master node fails. Once failure occurs, the other node
becomes master. This has been going on since we applied DST patch in
March. May be related, may not!
In reading NWCS documentation, adjusting the master node timeout under
second tab in C1 (cluster properties/protocol tab) to greater than 1
second may help out??

Has anyone suffered from this symptom?
