perfSONAR User Q&A and Other Discussion

[Chris Griffin <>]

I have just recently run into the same issue, although my symptoms were different.  
Upon saving I got "Error - Couldn't save Regular Testing configuration", but 
no errors in web_admin.log.  Tracked it to the same issue.  I am not sure if this is 
the best way to correct it, but try this:

* edit /etc/perfsonar/toolkit/configdaemon.conf
* change the "address   localhost" to "address  localhost4"
* restart the perfsonar-configdaemon.service

This seemed to start happening to us after a recent sent of patching and 
reboot activity.

Tnx
Chris
