ml2/ovn allows the configuration of the OVSDB session probe_interval, and defaults it to 60 seconds, overriding the python-ovs default of 5 seconds. It does this after the ovsdbapp Connection object is created and started, which means it is also after python-ovs sends a monitor request that pulls the initial copy of the database into memory. On a busy system with a large database, this can cause a failure since the 5 second default may not be sufficient to complete this request, causing a failure and infinite reconnection attempts with the error:
ERROR ovsdbapp.backend.ovs_idl.vlog [-] tcp:10.240.200.63:6642: no response to inactivity probe after 5.01 seconds, disconnecting"
3 years ago, functionality was added to python-ovs to pass the probe_interval value to the Idl so that it can be set immediately on the jsonrpc connection before connection, so we should use that.
