Thank you Andy, this is very helpful!

For a time, the entire BW box firewall is shutdown. No firewall!
(eeeek!)

Can you try reaching lcgnetmon02.phy.bris.ac.uk or run bwctl tests to it 
again? 

While no firewall, still errors of the kind you named are being seen in
/var/log/perfsonar/regular_testing.log:

2015/05/20 11:53:17 (3326) ERROR> MeasurementArchiveChild.pm:125 
perfSONAR_PS::RegularTesting::Master::MeasurementArchiveChild::__ANON__ - 
Problem handling test results: Problem storing results: Error writing 
metadata: Error running test from perfsonar02.datagrid.cea.fr to 
lcgnetmon02.phy.bris.ac.uk  with output bwctl: start_endpoint:

bwctl: run_endpoint: receiver: 137.222.171.39

bwctl: Unable to initiate peer handshake with [137.222.171.39]:6033 - 
canceling
bwctl: stop_endpoint: 3628747487.112685

So how can the firewall be the problem, if it's off?

Can you advise how further to debug what the problem is, if it's not 
firewall?

Very Grateful!!
