Qt notify badalloc

I mean that memory usage of appliacation in Windows task manager only increasing. It starts from 53 mb and when it become about 1 GB I get this crash.

So fix your code, I still fail to see any relation with exceptions. The problem is not when allocation fails but much earlier when you don't free memory you don't use.

What kind of problem I need to looking for? New/delete - ok. I don't overload events. For intercation between threads I use only signals and slots.

There is no point in guessing. Either use a memory profiler or analyze your code for allocated data you do not need. Be sure to use proper tools, Windows task manager is not a reliable tool for tracking memory consumption.
