Hello, We are setting up a container using a CLONE_NEWNS linux namespace. Previously we used the 3.4.4 kernel, which worked fine. After I upgraded i also experienced races in netlink, which has been resolved by placing a monitor around the namespace setup. When we upgraded to Linux 3.8.0 however our init processes does not get reaped when the namespace is killed and lingers as zombie process under the global init.
The init has multiple threads when running and two remain in the zombie. One of them is hung in zap_pid_ns_processes() and has been set uninterruptible. The other one, which has Tgid=PID, is still in do_exit(). -- Caj Larsson, Omnicloud -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
