We have had problems of that nature that derive from a bug in RSRV, the
server in the IOCs, for 3.13 IOCs. The IOC loses contact with the client
(e.g. Gateway) and marks the circuit as down but doesn't close the socket.
The Gateway thinks it is still connected and continues sending out its
cached data. There is no way to make the Gateway reconnect except to
restart it. All channels in the circuit are affected. (A circuit is all
the connections between one client and one server, all associated with the
same TCP/IP socket.) Other Gateway circuits are OK. The problem seems to
be associated with a lack of MBUFs in the IOC at some time. There may be no
memory problems later when you look at it, however. This problem was fixed
in 3.13.10, and RSRV now closes the socket so that the Gateway knows it is
disconnected.

But other channels on the same IOC (i.e. in the same circuit) are ok. I
have never seen the same error with other clients but the gateway.
