Hi again,

Here we have TCP/IP on an MVS mainframe and use it (just recently) to
spool output directly to Linux via lpd. Many times it will fail to
complete leaving a message 'TCPIP ERR=CONNECTION REFUSED' on the
mainframe when no refusing is being done ;). If there are more than one
jobs on the queue to come over and the first one succeeds, the second one
always fails with the same error. Below is a tcpdump of this exercise
where the first one succeeds, and the next one fails.

Anyone have any ideas?,
JES
