Passenger 2.2.2 error

Hi,

I deployed an rails 2.3.2 app on passenger 2.2.2.
I get the following error sometimes.
Is it something I can fix in my app or not?

Passenger encountered the following error:
The application spawner server exited unexpectedly: Broken pipe

Exception class:
PhusionPassenger::Railz::ApplicationSpawner::Error
