memory leak - where?

[Tomasz]

Of course you shouldn't be closing a connection with an active query and you will get a warning on the console when doing so. You should clear all the queries and only then close the database connection.

In this case I don't get any warning in my console. I'm only observing growing memory usage ('top' command), which disappears when I clean before closing. I'll think I need to learn more about using database in QT. I've got some questions about that problem but I'll search for answers in thread more connected with databases. Thanks!

best regards
