Re: 1 build run at a time

[James Nord]

You could define a single lockable resource and then ensure all your jobs 
grab it.

Re: Master Jenkins High CPU utilization

[James Nord]

Hi Dhaval,

A single thread dump (or even multiple) is not enough to see why the server 
is consuming excessive cpu.

https://stackoverflow.com/a/29148553 will show how how to track the CPU to 
a specific (or set of) java threads.
Once armed with that, then the thread dump will help us see what those 
threads are doing and may give an indication as to how you can fix or 
prevent it (or if it looks to be a bug aid in filing a detailed bug report)

Re: How to fix workspace deletion on slave node

Can I set the following arguments?. Will it resolve my problem

 How shall I fix this issue?

 While referring to some forum advising to fix 
 *hudson.model.WorkspaceCleanupThread.disabled* [ false ]. However, I 
 am unable to find this parameter.  

 Guide me on how can I fix this issuer permanently & save my workspace 
 and build.

 I see one option in Jenkins is DISCARD OLD BUILD. However, I assume 
 that check is to retain the build (to see the history) on Master Jenkins. 

 If needed I can help with some more information.

Jenkins user is no member of docker group

[Chris Dams]

Dear all,

I have a jenkins slave running on linux (jenkins version 2.249.2). The 
strange thing is that when I log into this slave via ssh using the jenkins 
account I can see (using the groups command) that 'jenkins' is member of 
some groups, including the docker group. However, when I put an "sh 
'groups' "line in the Jenkinsfile this user jenkins is not a member of any 
group besides the 'jenkins' group. This is a problem because it means that 
I cannot do a docker build from this jenkins file. Some time ago this used 
to be work but it stopped working for no apparent reason.

Do any of you have any idea what to do about this?

Thanks in advance!
Chris

Re: git-plugin 4.7.1 fails

[Mark Waite]

I've seen reports of that type of failure when the agent JDK was outdated
or the agent.jar file was outdated.  I have the "Version Node Monitors"
plugin  installed on my Jenkins
instance so that I can see the agent remoting versions and agent JVM
versions that are connected to my controller.

Re: Empty error message box on clicking apply button in Jenkins 2.277+

[saqib butt]

Thanks, Mark, I am finally able to run the latest Jenkins 2.290 with all 
the latest plugins (no plugin in Plugin's Manager update queue) without any 
errors.

 Jenkins 2.277.1 modernizes the configuration form handling to use HTML 
 div markup for layout instead of using HTML table markup for layout.  The 
 changes are described in the Jenkins 2.277.1 webinar 
  and its slides 
 
 .

 As part of the Jenkins 2.277.1 changelog 
  and upgrade guide 
 ,
  
 the following steps are recommended:

- Remove unused plugins from your installation
- Remove deprecated plugins from your installation (like the 
findbugs plugin, the DRY plugin, the checkstyle plugin, the Visual 
 Studio 
Team plugin, etc.)
- Remove plugins with security vulnerabilities from your 
installation (like the TFS plugin)
- Update your plugins to the latest releases (this assures that the 
latest authentication plugins are installed before the Jenkins version 
upgrade)
- Upgrade your Jenkins version
- Upgrade your plugins to the latest releases (get the latest 
plugin releases for the new Jenkins installation)

 If that set of steps does not resolve the issue, then consult the list 
 of plugins with known tables to divs issues 
 .  
 Uninstall any of those plugins or volunteer to adopt those plugins and 
 provide the necessary fixes for them.

 If all those steps still do not resolve the issue, then open a bug 
 report at https://issues.jenkins.io with ALL THE INFORMATION REQUESTED 
 AT "How to report a bug" 
 
  including 
 the Jenkins version and the *names and versions* of all installed 
 plugins.  Forgive my shouting, but the common practice seems to be to 
 submit an issue "this is not working" without enough information to allow 
 others to help.  Days later, the submitter updates the bug report with the 
 necessary information and hopes someone will help them.

 Please don't open the bug report until you've completed all the 
 preceding steps.
