We started using ZK in production recently and run into some problems.
The user case is simple we have a central
monitor checks the ephermenal nodes created by distributed apps, if
the node dissappear, corresponding app will get restarted. Each app
will also handle SESSION_EXPIRE by shutting itself down...
Whats happening now is sometimes the central monitor will try to
restart the app, in the mean time the app runs fine and sees no sign
of SESSION_EXPIRED. Any clue what's going on here?
