@abstractj can you look into this one ?

[abstractj]

@simo5 sure!

@miminar is this URL correct? I'm getting 404 when trying to access the report.

@abstractj unfortunately the test results don't survive long. The latest accessible run is 3481 as of now (not mentioning anomaly 1​25​0).

@miminar thank you, I finally managed to reproduce the issue

Code to reproduce the issue:

#!/bin/sh

# Cleanup cluster resources created by this test
(
set +e
oc delete all,templates --all
exit 0
) &>/dev/null


oc new-app node

while true; do
   oc login -u testuser -p test --request-timeout=1ns 2>> log.txt &
   if grep -q "error" "log.txt"; then
     echo "Error found...leaving"
     exit 1
   fi
done

@juanvallejo I will definitely need your help on this. It seems something really tricky to debug.

Fixed in #15885
