Lucene.Net.Store.LockObtainFailedException

[GoogleCodeExporter]

What steps will reproduce the problem?

I recently experienced the following error across all individual blogs on a 
multi-blog setup.  The main page was unaffected.

Lucene.Net.Store.LockObtainFailedException: Lock obtain timed out: 
NativeFSLock@D:\domains\blogs2.sqlteam.com\App_Data\write.lock:

What is the expected output? What do you see instead?

What version of the product are you using? On what operating system?
2.5.1.0

Please provide any additional information below.

In further review I see the path C:\Projects buried in this error message.  
That's my local development folder.  Could I have mixed in development and 
production?

Note: This error came from production.

Stack traces always show the path which it was compiled from.
