title: One application pool keeps hanging IIS 7
body: <p>For some reason my application pool keeps crashing once in a couple of days. The biggest problem is that there are no logs about errors or warnings in my administrative events about this pool. (there are several warnings in other pools, but it is only this pool that keeps crashing). Changes I make can only be tested if they worked if I wait a couple of days.</p>
  
  <p>I tried to bring my code back to the stage where the problems did not occur, but this does not seem to help.</p>
  
  <p>Most crashes happen when the site is not very busy, although not that inactive that IIS shuts it down for inactivity.</p>
  
  <p>Windows server 2008 R2 (SP 1),
  IIS Build 7.5.76,
  Umbraco,
  Sql server 2008</p>
  
  <p>IIS logs: only showing some recycling of the pool (once every 3 hours)
  Rapid fail detection: disabled</p>
  
  <p>Where should I start with solving this problem?</p>
