Fisheye cannot be started.

The following appears in the atlassian-fisheye-YYYY-MM-DD.log:

Invocation of init method failed; nested exception is com.cenqua.fisheye.rep.DbException: org.apache.lucene.index.IndexFormatTooOldException: Format version is not supported (resource: ChecksumIndexInput(MMapIndexInput(path="<FISHEYE_INST>/cache1/cache/globalfe/idx0/segments_21t53"))): 0 (needs to be between -1 and -11). This version of Lucene only supports indexes created with release 1.9 and later.


The Fisheye indexes are corrupted.


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.

  • (warning) 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
