After recently installing perfsonar, i went through a lot of error here and there so i followed the perfsonar troubleshooting guide (+using command : yum reinstall pscheduler server / systemctl restart pscheduler-scheduler ) to finally get this kind of error message on /var/log/perfsonar/pscheduler.log  through all my nodes :

 

Jun 25 14:24:57 pfs-sonde-cmc-i3-01 journal: safe_run/scheduler ERROR    Program threw an exception after 0:00:04.458554

They’re errors, but they’re harmless.  The safeguards built into the services throwing them makes sure everything gets restarted and back to work.

 

The underlying cause is corrected in 4.3.
