After several hours my application freezes sometimes (not just during debug, but also on the client machines)
Two hours ago I started my application (using debug). My application gathers information from an SQL database all the time (using threads), but this part seems to work just fine even when the application freezes
After about an hour I noticed that the application stopped responding to input from mouse and keyboard (I have a mousemove event, mouseclick event, keypress event and keydown event, just to name a few. During freezing none of these events are fired, but the graphics (using GDI+) on the form is updated (based on information from the database)
On the form I also have a thread running, a thread that goes into an unlimited loop (only stops when the application closes) that does some work then sleeps for a number of seconds. For some unknown reason this thread has stopped (setting a break point where it should always hit is never hit). Any exceptions that should happen here should crash the application (though it should be impossible for it to throw exceptions there), so it's not because of a try-catch that it stopped
About 30 minutes later Visual Studio does exactly the same thing. I can bring VS to front (not "Not responding" messages, neither from VS nor from my application), but I can't press anything at all.
Does anybody know what could be the problem here?
Edit:
I have noticed that during these 30 minutes VS has cleared a lot of memory (it uses 200-400 MB less than usual)
