Mahadev konar commented on ZOOKEEPER-108:
-----------------------------------------

as far as I understand this patch .... 

the problem seems to be that the leader is sending the commit for sync's out of 
order. Is that true? 
Also I dont understand the reasoning behind moving the pedning syncs up to the 
servers?


> sync implementation reorders operations

> The current implementation of sync is broken. There is a race condition that 
> causes a follower to return operations out of order, causing clients to drop 
> their connections to a server.
> I'll be attaching a patch to fix this problem shortly.
