By manually shutting down the server and hacking the lease database, 
temporarily increasing the lease limit or waiting for one of the old 
leases to expire.

Not great options.

We're a small operation and this doesn't happen frequently enough for us 
to worry too much about it.  We also use short leases (1 hour), so that 
helps minimize the occurrence and impact.

I once gave the OMAPI docs a quick look and it didn't appear that it was 
possible to exipre or otherwise release an active lease.  Maybe an OMAPI 
expert can chime in.
