[Zookeeper-user] Session timeout

[Avinash L. <avi...@gm...>]

How do prevent my session from timing out? I get this exception:

Priming connection to java.nio.channels.SocketChannel[connected local=/

I have set my session timeout to 5000ms in the ctor of the Zookeeper
instance. I have my Zookeeper instance running in colo A while the clients
that are using Zookeeper are located in colo B and C. Is this ok? Why would
this happen and how can I prevent this from happening? How should the
software react to this situation?

Thanks in advance
