It's repeatable. It doesn't happen on debian jessie.
Sheepdog daemon version 0.9.0_244_gff8590b
reported by @sirio81
The bug is repeatable using zookeeper on debian wheezy (3.3.5) or on zookeeper on debian jessie (3.4.5)
I cannot reproduce this issue on Sheepdog 0.9.0_244_gff8590b, ZooKeeper 3.4.8 and Ubuntu 16.04. Sheepdog 1.0_65_gb6d64b2, neither.
