Recovering after errors

I've been having trouble lately with refdb crashing after errors and
then being extremely difficult to restart. A typical cause for something
like this might be an incorrect command-line option (I once used -t for
the file name instead of -f and was forced to use control c to abort).
After an error like this, refdb seems to lose contact with its databases
Mysql, however, is still working.

I've tried several things to get it running again from using refdbctl to
stop and start, to restarting mysql and apache2, to removing my
configuration files and reinstalling refdb with the installation script
(often when I come to do this there is one or more refdbd sessions not
properly killed off and immune to refdbctl [I kill them manually])

I usually get set and viewstat to work in refdba, and can usually
selectdb and use whichdb in refdbc. But things hang up the moment I try
to add any references.

Any ideas what might be making it so unstable? Here's the log of my last
session. I image the problem is the lost version file
at /usr/local/var/lib/refdb/db/DB_VERSION. In refdbdrc this path is
given as /usr/var/lib/refdb/db/ so I'm not sure what is telling it to
look in this (non-existent) directory unless something in the setup has
missed my original prefix parameter:
