Symptoms

Error from the log:

[java] com.cenqua.fisheye.config.ConfigException: Unable to fetch from remote repository: /Users/mg/work/crucible/fe-hg - [transaction abort!, rollback completed, abort: data/src/content/WEB-INF/classes/xwork-crucible.xml.i@bb83fe00bd3a: unknown parent!]

Cause

Mercurial repository can sometimes invalid.

Resolution

Use the "hg verify" command to verify the integrity of the repository. If it returns an error, please try the following steps in Fisheye:

1. Stop your mercurial repository completely
2. Locate the mercurial repository cache directory e.g FISHEYE_INST/var/cache/hg-repo/
3. Remove the clone directory
4. Restart the mercurial repository so Fisheye will re-clone the repository. Note that you don't need to perform a reindex, it should back to normal after that.
