Yesterday (May 6), one of my agents failed a build due to, “Cannot run program “nohup””: ```auto java.io.IOException: Cannot run program "nohup" (in directory "/var/lib/jenkins/workspace/tinker"): error=2, No such file or directory ``` Today, I am digging in, and it is immediately apparent that this issue is occurring on ALL of my agents: - When a `sh` step is called: Jenkins fails to find “nohup” > ℹ My agents are running RedHat Enterprise Linux 8 and 9. Possible cause (or red herring fallacy): I did just update from Java 11 to Java 21 on May 2, 2024. > Note: Three of my nightly builds ran fine using Java 21 (on May 3rd, 4th, and 5th, at midnight PT). > Finally, on May 6th, it began failing. I will try out using Java 11 again and report back. Thanks for any help! ## Jenkins setup: Jenkins: 2.452 OS: Linux - 4.18.0-513.9.1.el8\_9.x86\_64 Java: 21.0.2 - Red Hat, Inc.

Welcome to this community, @ryeleo, and thanks for the feedback. 👋 Now, the question is: why are you facing this issue with Java 21? 🤔 Can you run your tests with a [Temurin JDK21](https://adoptium.net/installation/)? ---
**Author:** ![mawinter69](https://dub1.discourse-cdn.com/flex013/user_avatar/community.jenkins.io/mawinter69/32/1625_2.png) [@mawinter69](https://community.jenkins.io/u/mawinter69)\ **Post date:** [May 7, 2024, 3:58pm UTC](https://community.jenkins.io/t/cannot-run-program-nohup-on-redhat-jenkins-agents/14911/4 "2024-05-07T15:58:34Z")
This happens when you run a `sh` step? You might want to set `org.jenkinsci.plugins.durabletask.BourneShellScript.USE_BINARY_WRAPPER=true` via script console or permanently as a java property in the java command that starts jenkins (`java -Dorg.jenkinsci.plugins.durabletask.BourneShellScript.USE_BINARY_WRAPPER=true ... -jar jenkins.war ...`) ---

We also use RHEL8.9 agents with JDK21. We’ve been using this setup without issue for approximately 2 months. We’re on Jenkins 2.463 and have upgraded a couple of times in the last few months. We just started seeing the same error about nohup, but it only appears intermittently. Some builds run without issue, others throw an exception when using `sh`. Is there any additional information on this issue? edit: downgrading RHEL8 agents to JDK17 appears to have fixed the issue for us. ---

Some additional info, after downgrading to JDK 17 the issue was resolved for approximately one day and then later resurfaced. We use GCP VMs running RHEL8 as Jenkins agents. These are created by Jenkins from an image. The image had JDK version 17.0.11 installed. Jenkins picks up this version of the JDK. dnf-automatic was installed on the VMs, and after about 5 minutes of uptime dnf-automatic was upgrading the JDK version to 17.0.12, but Jenkins already read the version as 17.0.11. Removing dnf-automatic so the JDK version remains at 17.0.11 appears to have fixed the problem ---

Hi, same here, rhel8 and rhel9. With JDK 17.0.12 all my pipelines break with nohup not being able to run, while 17.0.11 works fine. Is that more a java or a jenkins issue? Or even a security policy thingy? ---

Thanks for the advice! This does maybe seem to get me past the ‘nohup’ issue, but I am now running into similar issues: Contxt: I re-upgraded to 21 around July 2nd. For a month, all seemed well. However, yesterday, I am starting to see issues with Java 21 not finding executables again! Specifically, this morning I am seeing that Jenkins is unable to find the following executables so far: - nohup - cp - python3.11 I was surprised that `org.jenkinsci.plugins.durabletask.BourneShellScript.USE_BINARY_WRAPPER=true` did seem to get me past the `nohup` issue, but now I am running into issues with `cp` and `python3.11` being unavailable (but they certainly are available. I’ve confirmed the `jenkins` user can indeed run `cp` and `python3.11` on my agents.) ---

Do you have by chance automatic updates enabled for java in your package manager and java was updated but your agents were not restarted? See 2 comments above from @ciaconet ---

There is a chance that it has something to do with java being updated automatically via our patching process. I can look more into this. I will try restarting my Jenkins Controller entirely, which I believe should have the effect of restarting all of the agents as well. Note: I am debugging this and it seems that even the most simple pipeline is failing to run due to: `Caused: java.io.IOException: Cannot run program "/var/lib/jenkins/caches/durable-task/durable_task_monitor_555.v6802fe0f0b_82_linux_64" (in directory "/var/lib/jenkins/workspace/tinker"): error=2, No such file or directory"` ---

Restarting my Jenkins Controller using does seem to have fixed my issues this morning for most of my pipelines. 😵 ---

Per @mawinter69, I checked if Java 21 was recently updated. It does indeed seem that it was which does correspond to the issues I’ve been seeing most recently! ```auto $ yum history | head Not root, Subscription Management repositories not updated ID | Command line | Date and time | Action(s) | Altered ------------------------------------------------------------------------------------------------ ... trimmed for brevity... 142 | -d 0 -e 1 -y upgrade java-21-openjdk | 2024-08-06 02:02 | Upgrade | 2 ... trimmed for brevity... ``` ---

In my case, this error was caused because of the wrong java PATH (typo). You can test a freestyle job on the same node you have an issue. It was failing running java --version The wrong PATH was set in /etc/systemd/system/jenkins.service.d/override.conf But it can be in /etc/default/jenkins too. Fixed the PATH, now, no more this specific error after restart of Jenkins. My distro is Debian FYI.
