Folks,

We've an old IBM F50 system running AIX 5.3. When we access the system
via a locally attached console it freezes up after a while, with the
only way to regain console access to restart.

Also, commands like Ping and the majority of the SMIT menus cause the
console to freeze also. The strange thing is that none of the same
commands cause a problem if we telnet in to the box.

Would anyone have any ideas or have seen this kind of situation
previously?

Thanks a million,
Boysey

perhaps the terminal setting for the console is wrong.
also, i would guess that you could still login remotely and restart the
console services from there.

What kind of cable are you using to connect the console. If it is not
a "full handshaking" null modem cable and you have the "clocal"
parameter set on the terminal characteristics this can happen if you
are not using Xon/Xoff pacing. Check the tty settings using SMIT to
make sure you are using Xon/Xoff pacing.
