----
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.

Experienced also the Badness in sk_del_node_init today when playing around
with some of the applications.

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.

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.
