Use db_verify to validate the structure. I'd suggest using -h to specify
a home directory that is different from the default.

Again, use -h to specify a different home directory. It sounds like you
had a catastrophic failure, so use the -c option, too. See
http://www.sleepycat.com/docs/ref/transapp/recovery.html, which might not
apply if you aren't using DB's transaction support.
