You can check logs by running: make check-valgrind TESTSUITEFLAGS="246"
(Actually almost every test affected but for example we need one test)
Valgrind message looks like
==65437== 304 bytes in 1 blocks are possibly lost in loss record 265 of 289

I also noticed that ovs-vswitchd calls ovsrcu_exit() before exit:
https://github.com/openvswitch/ovs/blob/0187eadfce4505d502e57c0e688b830f0a1ec728/vswitchd/ovs-vswitchd.c#L150
I also stopped a thread pool by calling run_update_worker_pool(0); because
ovsrcu_exit(); stucks without it.
