Redmine

Hi,

I created a project in redmine and connected a git repo to it. I made a post-push hook in git which updates the code and revision list in redmine as well when I push the changes. Awhile it worked well, the code and the revision list was updated correctly, but now I only see two revisions. (and in the original repo there are 18 revisions) In the repo browser the last modification times are correct and I can see the latest files, just the revision list is not up to date. In other projects the update works well, the problem occurs only in this project. What can cause this?

Redmine: 2.6 (stable)
Ruby: 1.8.7
Rails: 3.2.19
MySQL: 5.5.41
