This section is specific for troubleshooting under UNIX. For general problems and
solutions, please see previous Section "General Troubleshooting".
1. During system reboot, error message “WARNING! C218 Turbo/PCI
(XX000;BusNo=X;DevNo=X) not found!” appears.
The possible cause is memory conflict or defective board. Please shutdown the
system first, and then refer to the corresponding problem and solutions in
previous Section “General Troubleshooting”.
2. During system reboot, error message “ERROR! C218 Turbo/PCI
(MemBank=XX000) download failed!” appears.
The possible cause is memory conflict or defective board. Please shutdown the
system first, and then refer to the corresponding problem and solutions in
previous Section “General Troubleshooting”.
3. MOXA port responds too slowly or abnormal key operation.
The applications are not compatible with the C218
Turbo
/PCI On-board line
discipline. The only way to work it around is to set On-board line discipline
feature to “Disable” in [Board] sub-menu of Advanced configuration (Section
“UNIX” of Chapter “Software Installation”).
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.
