Insane CPU usage on Firebird v 1.0

Hi Launched a customer-facing e-commerce site last week using PHP talking to Firebird v 1.0 Everything looked sweet until I started getting PHP-level errors about not being able to connect to the database. Check the box the database is running on (2.8 GHz dual processors) and running top found that gds_inet_server is munching 100% of resources, even with as few as 10 connections open. More worrying, some processes are staying alive like the goddamned BeeGees, in excess of half an hour at a time. I explicitly close every connection to the database in my code with ibase_close(); Thoughts? Things I should be looking into? Is there a convenient laundry-list somewhere of issues relating to CPU-munching in Firebird so I can check out each one? I've currently disabled database connections on the site, making it pretty but useless. I really need help on this one. All comments, thoughts, insights, guru-like solutions, etc, appreciated.
