I have a server daemon process running on the master node listening on a
unix domain socket. I see the following stack dump when multiple clients
try to connect to server (send data to server) and close the socket at
the same time.

Only fixed Badness in sk_del_node_init.  User is still seeing
rmtunix_release_rmtpair assert.

Hi,

I still see this on a system checked out from cvs today.
Aug 13 06:43:17 localhost kernel: Assertion failed! rerror != -66,
cluster/ssi/ipc/rmtunix.c, rmtunix_release_rmtpair, line=850
Aug 13 06:47:01 localhost kernel: Assertion failed! rerror != -66,
cluster/ssi/ipc/rmtunix.c, rmtunix_shutdown_rmtpair, line=930


I see it in the syslog when i try to connect to a mysql-server running on
the init-node via mysqld.sock linked to another location in the
filesystem
with ln -s.

The assert has to do with object migration.
