Environment:openjdk version "1.8.0_45-internal"
Ubuntu 15.04
workflow-cps 2.26
pipeline-model-definition 1.0.1
core 2.32.2
After an hour or so of running 101 concurrent "hello world" pipeline scripts, the Jenkins server becomes unresponsive. The first signs of trouble in the log around here - I'll attach the entire log as well. The attached one probably has a bunch of noise in it from some earlier work.
The pipeline script itself looks exactly like this:
pipeline {
agent any
stages {
stage("TestingTesting") {
steps {
sh 'echo Hello world'
}
}
}
}
