Cisco CAD Troubleshooting Guide

If the values for those counters for a process are a significant part of the
total memory used, it may be of concern. Note that certain processes will
normally use more memory than others.

■

Try rebooting the computer and see if it fixes the problem. Check how much
and how fast processes increase their memory usage.

CPU Check

■

Ensure that the computer’s processor is at least the minimum required for
CAD and other installed software. If the processor is below the recommended
level, it could be the cause of the problem.

■

Use Task Manager to sort processes/applications by CPU usage. Check which
process seems to be using the CPU most of the time.

■

Use Windows Perfmon (perfmon.exe) for additional CPU checking.

— Add the %Processor Time counter for Processor > _Total and each CPU as

well as Process >_Total and process of interest.

— Check which process seems to be using the CPU most of the time.

— If the counter values for a process are a significant part of the total CPU

use, it may be of concern. Short spikes are acceptable but a significant
time with high CPU usage is of concern.

■

Try rebooting the computer to see if it fixes the problem.

Blocked Ports Check

To check whether a port is blocked:

■

Using telnet:

1. Ensure that the service is running and active.

2. From the command line, type the following command and press Enter,

where <hostname/IP address> is the hostname or IP address of the
service computer and <port> is the port the service is listening on.

telnet <hostname/IP address> <port>

— If the telnet operation is successful, the command window will clear.

— If the telnet operation fails, a connection failure message will appear.

■

Check firewall settings on the client and server computers.

■

Check firewall logs.

■

If security software is running on the computer, check its reports and/or logs
to see if it is blocking any communication or ports.
