I have a problem with my Jenkins which runs on K8s. My Pipeline is built with 2 pods - Jnlp alpine (default for k8s) and Maven (3.6.0 based on java-8:jdk-8u191-slim image). From time to time, after staring a new build it's getting stuck with no progress with the Build.

Entering the Pod:

Jnlp - seems to be functioning as expected

Maven - no job is running (running ps -ef).

Appreciate your help.

Tried to pause / resume - not solve it. The only way is abort and reinitiate the build.

Jenkins version - 2.164.1

My pipeline is :

properties([[$class: 'RebuildSettings', autoRebuild: false, rebuildDisabled: false], 
    parameters([string(defaultValue: 'master', description: '', name: 'branch', trim: false),
    string(description: 'enter your namespace name', name: 'namespace', trim: false),])])

    def label = "jenkins-slave-${UUID.randomUUID().toString()}"
