Additional info - jps can't see even itself if that is of any help.
I googled this:

This led me to test the content of /tmp and indeed there is difference:

See the difference at hsperfdata_jboss user, maybe that can help. I don't know why
jboss user has different.

jps can't see server process in Openshift
-----------------------------------------
Key: WFWIP-221
URL:
https://issues.jboss.org/browse/WFWIP-221
Project: WildFly WIP
Issue Type: Bug
Components: OpenShift
Reporter: Jan Blizňák
Assignee: Jean Francois Denise
Priority: Critical
This is somewhat curious issue.
When pod of app image is deployed (server is started) and switch to terminal in Openshift
GUI, doing `jps -l` does nothing although I can see in logs that server is up and I can
find java process in /proc/*/cmdline (image has no `ps` utility).
This happens only in Openshift environment and it is a regression to what was working
with latest published CD image.
Funnily, when I try to run the image in docker and start the server by
/opt/eap/bin/openshift-launch.sh, then jps can see the java process.
{code:java}
# this works fine
docker run -it
docker-registry.upshift.redhat.com/kwills/eap-cd-openshift-rhel8:18.0-EAP... sh
sh-4.4$ /opt/eap/bin/openshift-launch.sh &
sh-4.4$ jps -l
{code}
