    Description

      We've been running this database for a little over 6 months now without any issue. Yesterday I got an alert that the server only have about 2gb of data left so I log on to the server, shut mongod process down (it was running 2.0.2), delete the 10gb of log, and restart it.

      Server startups fine. I am able to access most of the database on the server just fine except for 2 databases (CrawlMeta and CrawlQueue). Every time I try to do any type of query against these databases, I would get errors like so:

      Tue Mar 27 14:15:44 [conn1] CreateFileMapping failed d:/data/db/CrawlQueue/CrawlQueue.141 errno:1006 The volume for a fi
      le has been externally altered so that the opened file is no longer valid.
      Tue Mar 27 14:15:44 [conn1] assertion 10085 can't map file memory ns:CrawlQueue.system.namespaces query:{}

      Looks like QueueMeta have about 160gb of data and CrawlQueue db have about 275gb which is fairly large but it isn't a whole not (not as large as our linux clusters). Mongodb is running as a single instance (not sharded or replicated) with journaling enabled. The server have 56gb of ram.

      Since the initial startup errors, we've attached additional hard drive that have about 1.6TB to the machine & moved all the data over to this new drive D:\ (data was initially on drive C:). However, after moving the data over, the same error still comes up. I notice the OS only has 1gb of swap enabled so I bumped the swap size to 300gb. That didn't fix it.

      Please see the link for client errors and server-side logs: https://gist.github.com/2220521

      I'm not sure how to get this backup and running again. I've tried version 2.0.4 with the same issue.
