.NET 4.0 System.Timers.Timer seems to not execute the elapsed event after some time

Question

I have a class that needs to run 24x7. It uses a Timers.Timer to execute an elapsed event in a calculated interval. After some time, 3-5 days, the timer just stops executing

Answer 1

If your system real-time is not very strict, you try to

if (next > 10)
        {
            return next;
        }
        else
        {
            return 10;
        }
