Resolution
Resolution #1 - Restore from a backup (recommended)
Restore the Fisheye data from an available backup (see Backing up and restoring Fisheye data for details)
Resolution #2 - delete the cache
We suggest using this option only when a backup is not available. The cache will be regenerated by Fisheye after the startup.
Please backup the full $FISHEYE_INST directory and the database before proceeding- Make sure Fisheye is not running
- Remove the <FISHEYE_INST>/cache/globalfe/idx0 folder
- Start Fisheye
