perfSONAR User Q&A and Other Discussion

[Rune Stromsness <>]

A fresh new perfSONAR 4.3.2 install on CentOS 7 from this morning was
working as expected for a bit as I manually added new scheduled tests
through the web GUI interface.  Then it has gotten into a state where
any time that I visit the GUI page for configuring scheduled tests it
just spins apparently indefinitely with the Loading notice without any
of the existing tests ever showing up there.  (This is true from various
browsers and browser sessions.)

The troubleshooting information I've found in a few hours of poking
around the web pages and looking through mailing list archives all look
healthy to me, including:

psconfig pscheduler-tasks

appears to succeed and show me everything that I had configured.


Restarting perfsonar processes and then rebooting the server haven't
changed the behavior, and I don't see any obvious errors in any logs I
can find.


Any suggestions on how to figure out what is causing this to hang, or
how to recover from this condition?
