Subject Zookeeper doesn't allow to reset
Date Thu, 13 Nov 2014 18:52:23 GMT
Hi folks,

I have 5 zookeeper server. I want to stop and reset it. I do this steps for
a while and worked fine, but today when I try such job, always it gives me
the following statistics:
Zookeeper version: 3.4.6--1, built on 11/11/2014 00:35 GMT

First of all, I want Zxid start from 0x00000. I am really wondering from
where does transactions (0x10000000f = 15) come from? 
By the way, I also confirm deleting all datadir and log history in each
zookeeper server before I start running the zookeeper.

Secondly, when I am trying to establish new connection (client) with above
state. It gives me an error like "Error occurred during initialization of VM
java.lang.OutOfMemoryError: unable to create new native thread"

Can anyone help me with such issues?

Thank you

Ibrahim
