As regards the unable-to-allocate error previously cited from "Processing triggers for pscheduler-server"  on the testpoint install -- 

I did the obvious thing and add swap space, in the form of a 4GB USB stick. The install completes without any error or warning.

 

Most of the BeagleBone models are pretty short on resources and may simply not be capable of running pScheduler.  The Black has a quarter of the RAM we recommend for a test point, and I’d be willing to bet the swap rate, especially to a slow device, would be high enough to cause problems.  There are some other SBCs in the same price range that are less constrained and would probably run perfSONAR just fine.

 

Tests go further, but do not complete. Still working to make sure I'm not missing something before I start pasting results.

 

If you want to send me a couple of samples off-list, I’ll give them a look, but I’m really inclined to believe this may be a case of insufficient machinery.
