Most likely causes:
  • Setting is too low.
  • The application is taking too long for the current load.
Things you can try:
  • Try increasing the value of the setting.
  • Check that external resources (for example, disk, database, etc..) are performing at expected levels.
  • Check that the application has not deadlocked.
Links and More Information IIS will not allow more concurrent requests to an application than the serverRuntime@appConcurrentRequestLimit setting permits.
