IIS Worker Process Recycling and Prime Numbers

To prevent all your application pools from recycling at the same time ... you should follow the way of the cicada! No I haven't been smoking crack. The theory goes like this: if you have two application pools recycled every M and N hours respectively (where M and N are both prime) then their recycles will only coincide every M x N hours. So, for the default 1740 minutes (29 hours) and the next prime up (31 hours), you're only going to have the problem once every 37ish days!
