does your fairly large volume update use incremental commit? or does it
update thousands of records before committing?

> One of our users running Firebird 1.0 Classic on Windows 2003 Server

> IBserver to use large quantities of memory. We have checked the
> application using Memproof and there are no open transactions or
> memory leaks.
> Our app is written using Delphi 7 and we are using the TIBSQL
> component to update fairly large volumes of transactions in this
> particular function.
> It seems as if IBserver re-uses the memory (which we are monitoring
> with Task Manager) however it seems the only way to make it release
> the memory is to stop and restart the service.
> This is a bit problematic as the server is in use for at least 12
> hours of the day and is complicated by the fact the they are using
> Terminal Services for the client connections to the server, meaning
> that the client applications plus the IBserver are all running on the
> one machine.
