Jenkins JNLP slave is stuck on progress bar when need to run Maven job - maven

Question

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()}"
podTemplate(label: label, namespace: "${params.namespace}", yaml: """
