Jenkins not able to fetch code from remote git

Question

My jenkins build is suddenly not working now.The error is as follows:-

Fetching changes from the remote Git repository  > git config remote.origin.url <url> # timeout=10 ERROR: Error fetching remote repo 'origin' hudson.plugins.git.GitException: Failed to fetch from <url>     at hudson.plugins.git.GitSCM.fetchFrom(GitSCM.java:735)     at hudson.plugins.git.GitSCM.retrieveChanges(GitSCM.java:983)     at hudson.plugins.git.GitSCM.checkout(GitSCM.java:1016)     at hudson.scm.SCM.checkout(SCM.java:484)     at hudson.model.AbstractProject.checkout(AbstractProject.java:1270)     at hudson.model.AbstractBuild$AbstractBuildExecution.defaultCheckout(AbstractBuild.java:622)     at jenkins.scm.SCMCheckoutStrategy.checkout(SCMCheckoutStrategy.java:86)     at hudson.model.AbstractBuild$AbstractBuildExecution.run(AbstractBuild.java:528)     at hudson.model.Run.execute(Run.java:1759)     at hudson.maven.MavenModuleSetBuild.run(MavenModuleSetBuild.java:529)     at hudson.model.ResourceController.execute(ResourceController.java:89)     at hudson.model.Executor.run(Executor.java:240) Caused by: hudson.plugins.git.GitException: Command "git config remote.origin.url <url> returned status code 4: stdout:  stderr: error: failed to write new configuration file .git/config.lock 

I am not able to figure out the root cause. I have checked the permission and ownership for jenkins home folder which is /var/lib/jenkins:- drwxrwxrwx 17 jenkins jenkins 4096 Jun 25 04:30 jenkins

Permission and ownership of .git folder inside workspace folder of jenkins is:- drwxrwxrwx 8 jenkins jenkins 4096 Jun 30 21:51 .git

Please guide me fix the problem.

I was seeing the same issue, but disk space and VM memory were not the problem. What fixed it for me was making the job re-clone on build:

1. Go to the job's "Configure" page
2. Under Source Code Management → Git → Additional Behaviors, add a behavior "Wipe out repository & force clone"
3. Save
4. Build
