Git operations occasionally hang in Jenkins on Windows

8.1k views Asked by At

We are running continuous Jenkins builds of a Git project hosted at Assembla. Jenkins is running on Tomcat 6 under its own user and generally works fine.

However every once in a while (say once in every 10 builds), the checkout operation at the beginning of the build job simply hangs. At other times the Git tag operation at the end of the build also hangs. I believe this did not ever happen in command-line operation (on the same host with the same user).

When hung, the Windows process tree shows taskhost.exe ? tomcat6.exe ? git.exe ? ssh.exe

When externally killing the Git and ssh processes of a hung tag command, the following stacktrace is seen in the job console output - the error is strange since the directory mentioned already exists and has the private key installed.

hudson.plugins.git.GitException: Command "C:/Program Files (x86)/Git/bin/git.exe push <repository> <tag-name>" returned status code 1:
stdout:
stderr: Could not create directory 'c/Users/<user-name>/.ssh'.
    at hudson.plugins.git.GitAPI.launchCommandIn(GitAPI.java:779)
    at hudson.plugins.git.GitAPI.launchCommand(GitAPI.java:741)

Here is a full listing of the processes and handles (except the long list of Tomcat threads). The build task is currently hung on pull. Another strange phenomenon here is that there is a scheduled SCM poll every 5 minutes, but it hasn't run for a few days - it is probably also stuck somehow.

Here is the SSH search (from a different point in time than the list of processes above). I don't know what to make of it.

I may have solved this. I originally set up my SSH keys by generating them with ssh-keygen on a Linux machine. This generally worked, but Git would hang occasionally from Jenkins.

Now I've tried using the PuTTY tools to set up key-based authentication to my Git servers, using these instructions. I then set the GIT_SSH environment variable to the path to plink.exe. It seems to be working now, but it was always an intermittent issue. Hopefully it won't return...

In my case downloading plink from the PuTTY site and setting the GIT_SSH environment variable to use it solved the problem.

I solved it by:

  • setting the Path to Git executable to C:\Program Files (x86)\Git\cmd\git.exe (i.e. cmd and not bin!) and
  • by setting the environment variable %HOME% to $USERPROFILE
    (otherwise HOME defaults to $HOMEDRIVE$HOMEPATH, which was H:\ in my case, but typically $HOME is set to $USERPROFILE).

This is discussed at:

https://issues.jenkins-ci.org/browse/JENKINS-5413

You might run the script below in the Script Console:

Jenkins.instance.getTrigger("SCMTrigger").getRunners().each()
{
  item ->
    println(item.getTarget().name)
    println(item.getDuration())
    println(item.getStartTime())
    long millis = Calendar.instance.time.time - item.getStartTime()

    if(millis > (1000 * 60 * 3)) // 1000 millis in a second * 60 seconds in a minute * 3 minutes
    {
      Thread.getAllStackTraces().keySet().each()
      { 
        tItem ->
          if (tItem.getName().contains("SCM polling") && tItem.getName().contains(item.getTarget().name))
          { 
            println "Interrupting thread " + tItem.getName(); 
            tItem.interrupt()
          }
       }
    }
}

to at least clear up the issue ...
