Running it more often that that will result in handoffs being stalled.  \r\n\r\nFor more in-depth technical detail, this is a problem because when you run riak-admin vnode-status it sends a message to the vnode to gather the requested information. The message looks no different to the vnode than messages that are client or other cluster work. A vnode will only be considered idle when the receive loop times out. By default this timeout is set to 60 seconds. When a vnode hits that timeout a message is sent to the vnode_manager to say that it is idle. Once a vnode is idle, then finally at that point a partition handoff process could be kicked off.\r\n\r\n[0]:  http://docs.basho.com/riak/latest/theory/concepts/vnodes/#Vnode-Status"}}
