Hi,

For a while the lispflowmapping performance tests on Jenkins have been
failing, first intermittently, but now the Neon and Oxygen tests fail
almost always:

https://jenkins.opendaylight.org/releng/view/lispflowmapping/job/lispflowmapping-csit-1node-performance-only-neon/
https://jenkins.opendaylight.org/releng/view/lispflowmapping/job/lispflowmapping-csit-1node-performance-only-fluorine/
https://jenkins.opendaylight.org/releng/view/lispflowmapping/job/lispflowmapping-csit-1node-performance-only-oxygen/

This is the error message that I found most likely to be useful:
"Caused: java.io.IOException: Backing channel
'prd-centos7-robot-2c-8g-42785' is disconnected." see the bottom of
the full console log:

https://jenkins.opendaylight.org/releng/view/lispflowmapping/job/lispflowmapping-csit-1node-performance-only-neon/90/console

Performance jobs use two VMs for the tests, and it looks like during
the tests the connection from the main VM to the slave is broken. I
couldn't find any clues for the root of the problem in these logs.

Any ideas on how to fix this? Unless the problem is fixed, these tests
just waste infra resources, so the sensible thing to do would be to
disable them, which is not the outcome I would prefer. The only other
project that seems to still have performance tests is SXP, their tests
at least finish, but not without failures, so I don't know how much
they are affected by this issue. MDSAL used to have performance tests
too, but I cant find them anymore.
