If you receive this message when trying to start the TN3270 emulation
program, the HP-UX computer does not have enough inter-process
communication (IPC) queues configured. The TN3270 emulation
program cannot be started at present. (You may be able to start it later
when fewer users are on the system.)
The message is followed by other messages that tell you to clear this
condition using ipcs and ipcrm or both. If you do not understand how to
do this, contact your System Administrator.
