Red Hat Bugzilla – Bug 1473885
Uncaught errors cause login page redirect with no indication of error in browser or server logs
Last modified: 2017-08-10 10:24:11 EDT
Description of problem:
The JON login page has issues with error handling. When installing the JON server with incorrect settings or running on a VM that is short on the necessary memory you are unable to log into the JON Server. Without any errors showing up in the logs, or in the UI a successful login simply redirects back to the login page.
Version-Release number of selected component (if applicable):
Somewhat intermittent. Suggest putting JON on a host with 1G or less of memory to reproduce.
Steps to Reproduce:
1. Install and start server without the minimum memory - 1GB or less
2. Attempt to login with correct credentials - eg: rhqamdin/rhqadmin
Return to the login page with no error noted in the browser, nor in the server logs.
If the server is having issues, the expectation is a browser side error to be reported, or an error in the log file.
If the server has had OutOfMemory event, then there's no guarantee that any error handling is possible. That's because at the OutOfMemory, JVM might have removed the actual error handling from the memory.
Triage: Larry, Simeon, Filip - based on comment 1 and the fact that recommended memory for JON server is 4 GB and JON is in maintenance period closing as won't fix.
