perfSONAR User Q&A and Other Discussion

[Raul Lopes <>]

Hi Phil,

 

I worked on a couple of hosts yesterday, where increasing the shards didn’t solve the problem. I had to stop all perfsonar services (see [0]) and start them back on.

 

Regards,

Raul

Hi Phil, 

             One of my colleagues, Raul, reported what he believes to be a race condition causing services to not work: https://github.com/perfsonar/psconfig/issues/112

Could this be your problem (and solution)?

Chris

Well the fix didn't last very long, back to no results.

I'll rebuild and see if things start working.
