Subject Network issues?
Date Thu, 06 Dec 2012 16:39:56 GMT
Hi,

I have noticed the following pattern in our cluster today:

The leader reports:
 > Unexpected exception causing shutdown while sock still open
 > java.io.EOFException
 > ******* GOODBYE ... ********

All the other server report:
 > Exception when following the leader
 > java.net.SocketTimeoutException: Read timed out

This is a five node cluster running ZK 3.3.3 (yes, it's very old, sorry).

It all happened within the a second across the whole cluster. Does that 
sound like a network issue?

As a side effect, the database got corrupted as well. Anybody knows if 
this is a known issue in 3.3.3? I checked the release notes and JIRA 
tickets but didn't found anything that looks like the pattern we saw.

-Gunnar
