Hi Nick, Sorry for dropping late to the party ๐.
I have no idea what the root cause is, but maybe this will help with your debugging: http://64.119.130.115/ovs/3d8e7354f5e981dee3301268fc498efcec6521e9/testsuite.dir/2180/testsuite.log.gz The issue is p5 changes from disabled to listening and blocking afterwards: "> 2017-03-21T07:04:56.099Z|00088|ofproto_dpif|DBG|port p5: STP state changed from listening to blocking" This happens when you slow down the system. I managed to reproduce on Ubuntu as well (if I enforce parallel on all the tests) with the same symptom: ``` root@ubuntu:/home/ubuntu/ovs# cat tests/testsuite.dir/2180/testsuite.log | grep blocking +port <>: STP state changed from listening to blocking > 2017-03-21T17:04:36.128Z|00091|ofproto_dpif|DBG|port p5: STP state changed > from listening to blocking root@ubuntu:/home/ubuntu/ovs# cat tests/testsuite.dir/2180/ | grep blocking cleanup conf.db .conf.db.~lock~ ovsdb-server.log ovs-vswitchd.log run stderr testsuite.log root@ubuntu:/home/ubuntu/ovs# cat tests/testsuite.dir/2180/ovs-vswitchd.log | grep blocking 2017-03-21T17:04:36.128Z|00091|ofproto_dpif|DBG|port p5: STP state changed from listening to blocking root@ubuntu:/home/ubuntu/ovs# uname -a Linux ubuntu 4.4.0-31-generic #50-Ubuntu SMP Wed Jul 13 00:07:12 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux ``` https://patchwork.ozlabs.org/patch/741524/ will fix it because the port p5 is listening at one point.
