ERROR [http-nio-7990-exec-52] <username> @1WU14K3x805x122891x1 193.39.66.214 "POST /scm/<project_key>/<repository_slug>.git/git-upload-pack HTTP/1.1" c.a.s.i.s.g.p.h.GitSmartExitHandler <project_key>/<repository_slug>[10]: Read request from 193.39.66.214 failed: com.atlassian.utils.process.ProcessException: Non-zero exit code: 1
The following was written to stderr:
error: git upload-pack: git-pack-objects died with error.
fatal: git upload-pack: aborting due to possible repository corruption on the remote side.

原因

There may be several causes for this problem:

Cause #1 - Corrupted Git repository

The database has become corrupted (e.g. as a consequence of a filesystem corruption).

Note: cloning the repository directly on the filesystem (without using Bitbucket Server) may still succeed since a Git clone does not run any additional checks and assumes that the repository is in a consistent state.

回避策

Try to run the following commands to see if they resolve the problem:

• Stop Bitbucket Server
• Copy the $BITBUCKET_HOME/shared/data/repositories/<repository_id> folder. This is to make sure that a backup of the entire repository is available.

• Run the following commands from the $BITBUCKET_HOME/shared/data/repositories/<repository_id> path:

  git fsck --no-dangling
  git repack -adfln --keep-unreachable --depth=20 --window=200

• Start Bitbucket Server

If the steps above don't resolve the problem, the repository may be not recoverable. In this case, the situation can be resolved by restoring a backup generated prior to the corruption.
