Mercurial Loop error followed by locks on commit. Mercurial/Eclipse

Question

Error and eclipse info below. Basically I clone a repository, change one file and commit. The commit screen flashes I see the error in the log and when I go and try to commit again I get lock timeouts. I've cleared the locks and recovered the repository but always the locks. Anyone been through this and fixed it before?

Thanks Bill

Answer 1

Basically some local hooks in the HG install with precommit checks caused this error. Commenting out the HG add-ons solved the problem.
