It's from application where nothing happens - there's only window.

Sorry I'm very stubborn about this memory leak but I've wrote some applications and all of them works fine on PC but on ARM after some time applications starting to work very slow and it looks like everything freezes (especially applications which uses SQLite databases). I suppose It's memory leak (applications are not complicated). Maybe I should look for cause somewhere else?

thanks in advance
best regards
