Missing iddb queue files

If one or more queue files are not properly generated, then a failure may occur once the queue is full and begins searching for the missing files. Files may be missing as a result of being deleted, or if the hard drive is full and new files cannot be written.

The missing file failure causes the failed-retry value to begin counting as it attempts to find the missing queue files. Once the counter reaches the failed-retry value it triggers the DB COMMIT SUSPEND state.

To recover from this suspension, restart the iddb service. This regenerates all missing queue files.
