Does anyone know why the following panic would occur?

pmap_alloc_pv: pgi_nfree inconsistent

I have a feeling that this occurred during the daily run early this
morning (I was asleep at the time) since I didn't get the daily and
security report in the mail this morning.  I can't quite remember what the
stack trace was, but it was the result of part of a filesystem operation.
This is on -current as of July 26.

Thanks.
