title: Continuous Loop/Repeat causes Excel to Crash (after hours/days)
body: <p>I have some VBA code that runs every 15 minutes continually. This code runs fine at first but after a period of time (which varies from around 4 hours to 5 days) Excel crashes. </p>
  
  <p>It is not a VBA crash (with debug option) but it is Excel freezing and saying the application needs to be restarted.</p>
  
  <p>Am I trying to use Excel in a way it was not designed for? Should I be clearing some memory/cache to avoid this?</p>
