We have been using Interbase/Firebird with gvibDA for a couple of years and 
experience the same problem. I think there's a bug in the firebird/interbase gds library 
that fails under multi-threading conditions. The gvibDA is thunked, but gds still hangs 
under heavy load.

So, we're migrating to SAP DB, which is also much faster than Firebird (at least for our 
use case)
