Hi,

I have a developer reporting that they can't see the changelist they just submitted. I can see it when I search for their name, but when I go to the review I get a "Not Found or Permission Denied" error, and this appears in the logs:

It looks to be a permission issue, but I have no idea what file that could be. The repository being used looks to all be owned by the gerrit user. Any suggestions / ideas?

Its trying to create a file under ${SITE_PATH}/git/${project}.git/refs/cache-automerge/../

My guess is the cache-automerge directory or one of its shard subdirectories is write protected or has the wrong UNIX permissions and is not allowing the server process to create new files there.
