Hello,

We have a problem in the production where show collections doesn't show all of the collections,
but db.mymissingcollection.find() or db.mymissingcollection.count() shows the collection missing from the show collections command.

This happened on 3 servers - 2 Cetons, and 1 windows. Some time after (about 3 weeks) the bug just disappear, and after changing the mongo tables, starts again - not always, just sometimes.

We have no sharding, we do run the "use" command, and we cannot reproduce this. Restarting mongod service doesn't solve this.
