Blocker Hello,
We have started to see a major issue where Nodes (Slaves) are vanishing (disappearing) and reappearing on their own.
The strange thing is that the issue impacts and occurs only on nodes who run parallel pipelines.
During the multi pipeline parallel job execution, we see Nodes (Slaves) are vanishing (disappearing).
On the Jenkins side, when we try to access the node, we receive:
HTTP ERROR 404 Problem accessing /computer/Computer-2021. Reason: Not Found
One the client-side, the agent thinks it is still connected, but when we disconnect the agent and try to connect again we receive:
Failing to obtain http://jenkins:8080/computer/Computer-8021/slave-agent.jnlpFailing to obtain http://jenkins:8080/computer/Computer-8021/slave-agent.jnlp
java.io.IOException: Failed to load http://jenkins:8080/computer/Computer-8021/slave-agent.jnlp: 404 Not Foundjava.io.IOException: Failed to load http://jenkins:8080/computer/Computer-8021/slave-agent.jnlp: 404 Not Found

Out observation:
1) After a certain time has passed & the parallel pipeline job ended, all of the missing nodes start to reappear again. about 1~24 hours.
2) Reload configuration from disk, bring all the vanished slaved back instantly.
More information:
Jenkins server version: 2.212.2 (Runs on Windows Server 2012R2)
All Slaves are JNLP agents running on Windows 7.

Hi danielbeck,
I am not sure I understand the question.
If you are asking if we are using the Jenkins Configuration as Code plugin, the answer is no.
| Environment | New: Jenkins 2.212.2 (Runs on Windows Server 2012R2) |
Our environment consists of 400 slaves give or take.
All agents are running as windows service.
All agents are windows based VM on a VMWare host, Min Windows 7, Max Windows Server 2012R2.
All agent are fixed (Not created on demand).
Are you using Groovy script or Configuration as Code to automate stuff on your instance?
