Issue/Introduction

Seeing this entry repeatedly in the enterprisedashboard.log file:

 java.util.prefs - Couldn't flush user prefs: java.util.prefs.BackingStoreException: Couldn't get file lock. 

Cause

This issue can happen due to not enough hard disk space in the DevTest server or it can be a permissions issue.

Environment

All supported DevTest releases.

Resolution

Check what is the hard disk space available in the DevTest Server.

The partition where DevTest is installed and the /tmp partition should not be close to 100% in use.

In Linux systems you can verify the hard disk space using the command:  df -h

If permissions issues, please open the permissions on the DEVTEST_HOME folder.
