Hi,
I'm trying to run simple pipeline integrated with Jenkins running on
OpenShift.
It was running fine before then I deleted the entire project and generally
was trying to reproduce all the steps but beforehand I built blueocean now
I just want standard openshift template... the problem is... I create a
jenkins project, I assign 8GB of memory to jenkins, I run x86_64 version it
starts up fine but as soon as I execute the pipeline it drops:
WARNING: Unexpected exception in CPS VM thread:

So it ran out of memory. It's strange as this happens as soon as I click
"Start pipeline". Pipeline is very simple and it literally git clones 4
files and should bild nodejs app (very simple).
java process is allocated with 4GB memory from some reason. I don't know
why. I run it from official template using openshift jenkins-2-centos7

Node has plenty of memory free:
[root@master ~]# free -m
total used free shared buff/cache
available
Mem: 15507 2940 8127 129 4439
12005
Swap: 0 0 0
Any ideas?
Thank you.
Regards,
TH
