Original issue 63 created by kresten.krab on 2011-12-22T16:39:27.000Z:

This is just a FYI. We've seen this odd behavior, when running out of disk space. In this particular LevelDB instance, we had ~500.000 files, of which ~386.000 were zero-length.

Let me know if you want more info for further investigation if you find this relevant.

Hi Kresten,

Thanks for the report.

(1) Can you send me the names of some of the zero length files? That will
help track down which part of the code was generating them.

(2) if there is a non-empty LOG file in the database directory,
the contents of that file could also help.

(3) Do you know what you were doing when this happened?
E.g., repeatedly opening the DB, or opening the DB once and
doing lots of writes to it, or opening the DB and just reading from it.
