title: GitLab projects failed their last repository check
body: <p>I have received a gitlab alert mail stating that &quot;One project failed its last repository check&quot;.
  I did check the error in Gitlab admin panel as &quot;Last repository check (just now) failed. See the 'repocheck.log' file for error messages.&quot; As suggested in Admin Panel in Gitlab, i have checked the repocheck.log file and the error is as below.</p>
  <p>&quot;Could not fsck repository: error: Could not read 0f188244898707e6090498bc03aafd8ac25e776e
  failed to parse commit 0f188244898707e6090498bc03aafd8ac25e776e from object database for commit-graph
  error: Could not read 4ab7111f3f8f1083cee8e33ec033c18edfefb0e9&quot;</p>
  <p>This happened the same with another repo last week. Even that had similar error message and it is not resolved yet. Tried to clone the same repo in another gitlab instance to recreate the issue but the repo check there seems to be fine.
  Unable to find proper solution for that. Could any one please help on this.</p>
