I have 7 shards and 1 Router and 1 Config server. All the shards and servers are running on VMs.One of the shards is allocated excessive data. This is the same machine that was acting up and exhausted all the diskspace in the previous issue that I have raised before. We deleted all the data and config and started on clean slate.
Could there be any problem with this machine in having affinity for taking more data- If so, what could be the reason?
I have raised a related issue which details the history of this issue
https://jira.mongodb.org/browse/SERVER-5433
Thanks

Observation: look at the mapped and vsize 1.95 and 4.42
All the other shards have similiar mapped and vsizes, except lrchb00319.
I am thinking this odd shard would take up all the data and then stop functioning as it runs out of diskspace. Please comment.
