jstack output from the process utilizing CPU

Description of problem:
Having BPM cluster on top of two EAP nodes in a domain, after a few minutes of working with a cluster node (cloning a repository, starting processes), CPU utilization of this node grows and stays above approx. 70%, although there is no more real load for cluster.

jstack shows several helix threads trying to synchronize niogit (attached), also please take a look at bug 1150123, as these issues are likely connected.

Version-Release number of selected component (if applicable):
6.1.0.DR3

Steps to Reproduce:
same as for bug 1150123

zookeeper cluster configuration

Alex,

as we spoke about configuration of cluster with 3 zookeeper nodes, unfortunately it did not help. After some work, CPU utilization stays high and messages in server logs keep coming. Could you please take a look at attachment with my cluster configuration? It's possible that I just made a mistake.
