Mike Matrigali commented on DERBY-6826:
---------------------------------------

given the current information no progress is likely to be made on this issue.  
Bryan posted the interesting questions.  
Running more detailed debugging on a copy of the db might provide more info.  
Here is a link to more info on 
Derby db corruptions, and how events external to derby can cause this issue:
https://wiki.apache.org/db-derby/DatabaseCorruption

The error happens when the db is booted, so every access to the db is going to 
continue to get this error.  

Any idea why you do not have derby.log messages prior to Thu Jun 18 00:20:26 
EDT 2015 when the error seems to 
have first happened in this log on a boot.  Since there are multiple boot 
messages in derby.log it does seem like you
have the property enabled to not automatically delete derby.log.  Any chance 
the db was copied or files were deleted by hand which may
have accidently included deleting files in the "log" directory?
