Dummy entries in persistentId store

[Alan Buxey]

you need to turn up some logging/debugging on the database.... maybe
the table is locked, maybe there are problems with eg too many
indexes...maybe there arent correct indexes so the update/delete is
intensive... look for slow queries, look at the queue...maybe the
account doesnt have correct privileges for that table?  the DB process
will have the answers   (you might also want to run a traffic dump
between your host and the DB to see whats flowing too)
