Hi!=20

We're seeing some problems in several mongos instances. We are running=20
master/slave replication and with really low traffic we're seeing 100%=20
mongo CPU usage in the master. When we stop the slave it automatically goes=
=20
to normal values.=20

We have proper indexes in _id field, and we use this to query the=20
documents.=20

> db.foo.getIndexKeys()
[ { "_id" : 1 }, { "i" : 1 } ]

Operating system is FreeBSD 8.2-RELEASE.=20

Mongo version is 2.0.2, but we're also seeing this situation in 2.0.4.=20

The tests we've done are:=20

With no replication running (slave stop):
