Cannot open channel to 1 at election address
Hy,
Why is this happening? I have 3 severs all have the same zoo.cnf and all
have access to all ports. Yet I get the below? The other 2 servers appear
to be working.

Hi David,
We often see this because servers start election at different times, but they later on catch up and elect a leader. If this persists, then you might consider checking ipchains configuration and such depending on which platform you're running ZK.
