Description Juan Hernández 2012-06-21 18:38:26 UTC
Description of problem:

The engine doesn't close the file descriptor used to open and read the .keystore file, as a result after some time file descriptors are exhausted an the engine is non operational.

Version-Release number of selected component (if applicable):

ovirt-engine-3.1.0-3

Not that this is the first 3.1 beta, before the change in the numbering schema for pre-releases.

How reproducible:

Always.

Steps to Reproduce:
1. Start the engine and wait.
  
Actual results:

The engine is non operational.


Expected results:

The file descriptor should be closed after use.

Additional info:

The following message appears repeatedly in the engine.log file:
