Re: [Zookeeper-user] Weird exception

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

Here is the exception I am seeing at the server on one of the machines. But
this happened in the morning at around 9/10 AM.
2008-07-09 17:33:34,607 - WARN  [FollowerHandler-/10.18.38.191:39598

I can start the client and see if this continues to occur. But the exception
still continues to surface on the client.
