Jenkins - Login Page shows up, but getting securityRealm / finishLogin ErrorID=e160bxxx-aaa-yyy-zzzz

Question

Jenkins version: 2.89.4 / 2.89.4.2-rolling

I can see the login page (clicking right top Log in link). Sometime it brings the login page (where a user can enter username / password) -OR- it's taking me straight to an error.. in either case.

Error:

In the address bar, I see this URL value:

http://jenkins-dev-server:8080/securityRealm/finishLogin?code=bc2c6a5a-b898-4a6b-96h7-e7jhcba59ytg

An error occurred processing your request. Ask your Jenkins administrator to look up details. ErrorID=gh425da7-0y78-4068-b2h9-c2bed48ke6sa

Stack trace suppressed by the suppress stack trace plugin

One of the job's status before this happened was showing FAILED (Red ball) but looking into the job's console output shows NO "error|failed|fail|aborted|fatal|memory" related errors (case in-sensitive). The last line in the console output is just a valid expected output (for ex: echo "hello world") nothing after that.

Answer 1

So it seems like, Jenkins home's mount (df -kvh ${JENKINS_HOME}) was 100% full. I know! new to the team.

• Will implement some good monitoring as soon as I get some elevated access.
