Look up errno 73 in your AIX /usr/include/sys/errno.h.  It is:

ECONNRESET      73      Connection reset by peer
                        A connection was forcibly closed by a peer. This
                        normally results from a loss of the connection on the
                        remote socket due to a timeout or a reboot.

*SM is client-server.  Whenever you have session problems and the client
messages don't tell you what's going on, you need to look at the other half,
the server Activity Log.  That should explicitly say what's happening.
The client can't necessarily say what the problem is, so an explanation may
not be available in the client side.
