[ovs-discuss] Delete port ,but the port is not deleted.

[ccdbpy at sina.com]

Hi everybody:
       I have a trouble.After nova executed 'ovs-vsctl --timeout=5 -- --if-exists del-port tapc6bd9ac8-ff' , the port is not deleted.
       I have examined the log of ovsdb-server, feeling surprise,as if the port is deleted, then is added again.
       I don't know what other people have done for this. Please help me.
       ovsdb-server log:(ovsdb-tool -mm show-log)
       
       [root at js02-compute-10e135e96e71 nova]# ovsdb-tool -mm show-log | grep tapc6bd9ac8-ff
