.NET windows service getting stopped abruptly

[Apopoxsic]

HI Guys,I have created a windows service which spawns three threads.The first thread wakes up every 15 sec, the second thread wakes up every min. and the third thread once in a day.My Code looks something like this:\[code\] var timer1 = new Timer(); timer1.Elapsed += ProcessTimerEvent1; timer1.Interval = 60000; timer1.Start(); var timer2 = new Timer(); timer2.Elapsed += ProcessTimerEvent2; timer2.Interval = 15000; timer2.Start(); var timer3 = new Timer(); timer3.Elapsed += ProcessTimerEvent3; timer3.Interval = 86400000; timer3.Start();\[/code\]From my event logs I can see that it is saying .NET Runtime 2.0 Error Reporting EVENTID:5000.I looked through the net and it says invalid operationexception.DO you guys think whether this stopping of service has to do anything with threads.And the other silly question is am I spawning 3 new threads everytime or the same threads gets up evey 15 sec or 1 min.
