Hi Patrick,

Have you tried the two patches Eric mentioned? One of my 4.1.11 server
just hanged with very similar stack trace and I am wondering whether the
aforementioned patches would help.


linux-4.1.12 definitely contains the fixes.

8ae3dfacdd82 inet: fix race in reqsk_queue_unlink()
31b8abd140ad inet: fix races in reqsk_queue_hash_req()

Please upgrade to 4.1.13 and you should be fine.


Thank you Eric and Patrick. I will upgrade to 4.1.13.
