Could you confirm the following bugs have been fixed in 2.2.2 please?

SERVER-2281 after a

"show dbs" hangs
SERVER-4291 Assertion: 13273:single data buffer expected whil using mongod

We have a single mongod instance installed on a blade server with linux OS at mongodb version 2.0.5 using authentication since December 2012. Last week we began experiencing issues using the mongodump utility. A bash shell script is used to perform fsync lock, mongodump each database, unlock. There are 11 databases sized at 0.203125GB and 1 database sized at 0.453125GB being backed up using mongodump. Fsync lock and unlock are javascript programs issued from within the script.

Thank-you!
