Jenkins / Bug JENKINS-54955
waiting for next available executor for too long
Issue Type: Bug Bug
Assignee: Carlos Sanchez
Components: kubernetes-plugin
Created: 2018-11-30 05:57
Environment: jenkins 2.89.4
kubernetes-plugin 1.8.4
kubernetes 1.8.8
Priority: Major Major
Reporter: l hy

We use kubernetes-plugin to dynamically create jnlp slaves, but when there were lots of build tasks (about 20), not enough slaves were created(only about 11 created).And it usually has to wait most of running slaves to finish then start to create new slaves.

Don't know why it works like this, we tried these steps:

1. start jenkins master with these flags

{{-Dhudson.slaves.NodeProvisioner.initialDelay=0
-Dhudson.slaves.NodeProvisioner.MARGIN=50
-Dhudson.slaves.NodeProvisioner.MARGIN0=0.85}}

2.change "container cap" and "max number of instances" to unlimit
