    Description

      We started inserting new data into more or less random collections but the lock ratio was very high. (>100% with just 60 inserts/s)

      After restart of mongo we started with inserts again and after few minutes the following error occurred in the log and mongo started allocating new db files like crazy. I managed to stop it before it filled the whole disk but it allocated some 50 new files. The process was stopped correctly.
