Hi

 

We are cleaning our workspaces and redeploying ...planned to repave and recreate.

 

Can you provide some information on how to enable extra logging in zoo keeper? We have following
in zoo.cfg
## The number of milliseconds of each ticktickTime=2000# The number of ticks that the initial#
synchronization phase can takeinitLimit=10# The number of ticks that can pass between# sending
a request and getting an acknowledgementsyncLimit=5# the directory where the snapshot is stored.dataDir=/var/zookeeper/data#
the port at which the clients will connectclientPort=2181# the maximum number of client connections.#
increase this if you need to handle more clientsmaxClientCnxns=60#minSessionTimeout=4000maxSessionTimeout=40000##
Be sure to read the maintenance section of the# administrator guide before turning on autopurge.##
http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance## The number of
snapshots to retain in dataDirautopurge.snapRetainCount=3# Purge task interval in hours# Set
to "0" to disable auto purge featureautopurge.purgeInterval=1

the zookeeper keeps crashing with following logs...
