Ack! Help! Key & Segment mismatch, and filepro reporting no space on the device...

[Silas Martinez]

Filepro 5.0.14 on Debian.

Not sure what happened, I assume power dropped while someone was in
update mode, and we ended up with a key& segment mismatch. Typically,
we can go into expand files and expand the affected file by one
record, and correct the problem. however, now, when we go to do that,
Expand Files reports room for 0 more records.

df reports plenty of space on the partition, and I can create new text
files without problem.

I've never seen this before - help, please!
