Timer stops after a while

I have an MFC application using 5 system timers with the following time-out values:

10 minutes

1 second

0.5 second

0.1 second

0.01 second

It seems that all timers stop generating WM_TIMER after the program runs for a few days and everything else of the program works fine.

Has anyone ever seen this kind of problem? Am I using too many timers draining too much system resorce? I have just combined the 0.5 second timer with 0.1 second timer into one to see if this helps.
