@rafaelweingartner You might be right that pod_vlan_map should be in the
join. May be I didn't find the correct methods after all. @jburwell @rhtyd What
do you think?
I was able to find management serve log for Deadlock 1. Looks like one of
transaction came from findAndUpdateDirectAgentToLoad method in HostDaoImpl
which creates rather complex transaction:
