lost ZK events across datacenters

I have a setup where multiple ZK clients are sitting in a different
datacenter from the ZK server. All clients registered the same child watcher
on a path. However, when the children of the path changed, the watcher on 1
of the clients didn't fire. This seems to have happened a couple of times to
me. I am using ZK 3.3.3. Has anyone used ZK in a cross datacenter setup and
seen problems like that before?
