Description of problem: During a heavy load test, debug logging was enabled on all OVS and OVN components. When the test completed, the ovn-controller log showed that ovn-controller had exited due to hitting an assertion: "ofctrl: assertion del_f->installed_flow failed in merge_tracked_flows()" This hasn't been seen before in "normal" testing. It is suspected that the extra debug logging slowed things down enough to result in hitting this odd case. Logs will be uploaded once they are gathered.
I am closing this because 1) Logs were never uploaded. 2) This assertion has not been seen since this initial reporting of it. This almost certainly was a bug in ovn-controller I-P. The number of fixes that have been made in that code since this was reported is high. The assertion likely was addressed already.
