no index records

[Joe Konecny]

Using 3.0.4 with FreeBSD 5.2.1...  Testing amrecover everything
went smooth restoring one file.  Tried it again right afterwards
and amrecover says no index records.  Couldn't figure out what
I did to cause it but figured it was me.  Ran amdump several
times since and no index records are being created.  In the
index dir last night it created on file called 20041015_0.gz
size was 20 bytes.  Indexing is turned on.  Any ideas on where
to look?
