So this shows that no remote pSconfig file is loaded but that you still have 
locally defined tasks running.  The toolkit-webui.json contains all the tests 
defined through the local webUI.  If, on the other hand, the webUI at 
https://your.node.tld/toolkit/auth/admin/tests.cgi shows you an empty list, 
there is a problem.

From your email on the ASREN list it seems that the content of this file is 
coming from a previously defined mesh, probably from an upgraded 4.0 
perfSONAR installation.  This part of the file tells it:

   "_meta" : {
      "psconfig-translation" : {
         "source-format" : "mesh-config-tasks-conf",
         "time-translated" : "2019-03-21T08:47:15+00:00"
      }

It might be that this interferes and somehow confuses perfSONAR.

To forecibly remove this task list, you can delete the 
/etc/perfsonar/psconfig/pscheduler.d/toolkit-webui.json file and wait at most 
60 seconds.  Look at /var/log/perfsonar/psconfig-pscheduler-agent.log and 
wait until you first get a message stating "Running agent..." and then, after 
a while and some other messages, a message stating "Agent completed running".

It can take some time (multiple minutes, even up to 20 or 30 mins if the host 
is heavily loaded like yours) to complete.  Once the message is printed, do a 
`psconfig pscheduler-stats` again to see if the list of tasks managed by the 
agent is now empty.

The load and the running tests should then hopefully start to decrease.  If 
that doesn't happen, maybe because of load and an unresponsive pScheduler 
API, wait 24h and then all tasks coming from the webUI should expire by 
themselves.

Let us know how it goes,

Regards,

Antoine.
