[ovs-discuss] socket handle leak when pkill/kill -9 ovsdb-server/ovs-vswitchd

[fukaige]

I am using ovs-2.5.2 and find there may be socket handle leak when kill ovsdb-server/ovs-vswitchd thread.
When I use “pkill -9 ovs-vswitchd” kill ovs-vswitchd thread and restart it, the socket file “ovs-vswitchd.12237.ctl” isn’t closed.
