The capped mongo collections take 50MB of data no matter what.

[sferoze]

The issue I am having with Kadira debug is that the 2 capped collection it creates in MongoDB, _kdtraces & _kdtimeevents take up 50MB of space each even if there are no documents in the collection.

I am using compose.io and I see _kdtimeevents & _kdtraces collection. Each have 0 documents inside and are still taking up 50MB of space each.

This is an issue because I use debug for many apps under the same cluster, and compose.io charges for total data in the cluster.

So this is adding a lot of storage to my plan and increasing the price.

Why are the capped collections taking 50MB of space no matter what? How can I fix this?
