perfSONAR User Q&A and Other Discussion

[Kathy Benninger <>]

After a reboot I'm seeing problems with regular testing on a perfSONAR,    
ps.psc.xsede.org

The errors in /var/log/perfsonar/regulartesting.log are 500 Internal Server 
Error :

2016/03/17 17:32:07 (14482) ERROR> EsmondBase.pm:53

metadata: 500 Internal Server Error at 
/usr/lib/perfsonar/bin/../lib/perfSONAR_PS/RegularTesting/Master/MeasurementArchiveChild.pm 
line 122.

Under "Test Results" on the homepage, there's a message:
  Error loading test listing: SyntaxError: JSON.parse: unexpected 
non-whitespace character after JSON data at line 1 column 5 of the JSON data
and, sadly, no test results.

Auto updates are enabled.  Before and after the reboot, the homepage listed:
   Toolkit version 3.5.1
   Toolkit RPM version 3.5.1-1

Before the reboot, the banner that comes up at login on the pS said
   Welcome to the perfSONAR Toolkit v3.5.0.7
After the reboot, the banner now says:
   Welcome to the perfSONAR Toolkit v3.5.1

Please advise.
