[ovs-discuss] How to crash ovs-vswitchd and ovsdb-server

Hi All, My requirement is my application should detect the crash in ovsdb-server and ovs-vswitchd application and do required relaunching applications. To test this I would like to know how to crash ovsdb-server and ovs-vswitchd application? I don't want to kill it by kill or other commands.

[ovs-discuss] why userspace handle many packets once?

If the packet can't match the flow table in the kernel module, it will be delivered to ovs-vswitchd. Recv_upcalls() is a part of ovs-vswitchd, the number of packets handled in recv_uopcalls()is UPCALL_MAX_BATCH(default is 50), could you tell me the reason why it's designed so? thank you!
