FInally found a runaway process with swish-e. However, I didn't realize
the bin was striped so no debugging symbols. I recompiled and installed a
-g version and removed the strip command, so if it happens again I might
have a better stack trace for you.

  Indexing happens under a user account, so it wasn't an indexing run.
