To confirm it wasn't FB itself, I changed the access to a MySQL db. This gave the same behaviour. So then I replaced the Zeos components with anot...

zippo : True, but I saw only small leaks - here we are takling about 120 MB in 30 minutes - my leaks are max 1-2 Mb in few days/weeks! The main app I am develooping is performing a LOT of data access (at least 10 requests a second, potentially much more). Therefore, these little leaks mount up to a ...

As a test, I connected the same program (above) to a MySQL database. I get the same symptoms with a rapidly escalating memory usage.
