When DHCP agent creates port from neutron and another create port request is received, ResourceClosedError occurs in sqlalchemy.
this may be related to bug #1282922 https://bugs.launchpad.net/bugs/1282922
Above bug is related to nec plugin and it is mentioned that other plugins may be affected.
This error occurred in ML2 plugin both for create and delete ports.
