[sheepdog-users] zookeeper followers hungs

[Maxim Terletskiy]

Hi!

I'm using three nodes zookeeper cluster and have problems with follower 
nodes. They are working normal about  12-24 hours, after that process 
starts to using 100% of one cpu core and stops to responding. Restart 
helps but not for long. Does anyone have similar problem?

There are warnings in logs:
2014-04-11 18:19:57,415 - WARN

Maybe my config is wrong?

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/lib/zookeeper/data
clientPort=2181
maxCnxns=0
server.1=node1:2888:3888
server.2=node2:2888:3888
server.3=node3:2888:3888

Zookeeper version is 3.4.5, OS CentOS 6.5 x86_64.
