If they are already running in the CS queue, here is the likely cause.  Is there some new monitoring in place?  If so, it may not be behaving well on the network. 

What happens is someone uses a telnet or ftp connection to monitor whether the network is up on the 3000.  They send the SYN, the hp3000 answers with the SYN ACK, and then the hp3000 receives a reset before the connection is complete.  This handshake sequence causes this exact error.

Also inetd and other HP3000 networking improved greatly in later versions of MPE/iX.  Or if they must stay on 6.0, they should at least be sure to install the latest patches.

Alan - who says they don't have support.  They obviously have Ron and us.

i'm pretty sure this is the old "inetd running the the D queue" problem.

add ";pri=cs" to the "!run" line.          - donna
