Intellio C320Turbo/PCI User's Manual 6-9
4. When respawning quite a few number of tty ports, the following error
messages appear: “Time out table overflow”, “File table overflow”, “Region
table overflow”.
The above error messages imply that the system resources are exhausted. You
should tune the kernel parameters to a larger value and rebuild the kernel to be
able to accommodate the new configuration. Refer to UNIX system manual about
how to tune the parameters and rebuild kernel.
“Time out table overflow” :NCALL parameter too small.
“File table overflow” :NFILE or NINODE parameter too small.
“Region table overflow” :NREGION or NPROC parameter too small.
5. The newly rebuilt kernel could not boot.
The Intellio C320Turbo/PCI driver might not be built into the new kernel
correctly.
a. Please use the last good kernel backup to boot again. The kernel backup in
SCO UNIX is /unix.moxa while in UNIX SVR4.2 /stand/unix.moxa.
b. Then remove the Intellio C320Turbo/PCI driver. Refer to “UNIX” section
of “Software Installation” chapter for driver removal.
c. Re-install the Intellio C320Turbo/PCI driver once more.
6. When using MOXA port for PPP/SLIP connection, what should the “On
Board Line Discipline” feature be set to?
Set to “Disable”. Otherwise the PPP/SLIP connection will fail.
