As the subject heading says I am experiencing extremely high CPU utilization by the EXEC process.
CPU utilization for five seconds: 97%/0%; one minute: 96%; five minutes: 96%
2 ME 80335584 8180376 129506 6316610968/12000 65 Exec
129 M* 0 584 262 222910080/12000 66 Virtual Exec
I have followed the trouble shooting guide on the Cisco site but this has not helped in fixing the problem.
I have attached the output from the Sh tech support command.
If anyone can help it would be greatly appreciated.

Is there perhaps a debug running?

Thanks lgijssel but all debugging is disabled.

From the show tech I noticed that you are running a very old IOS version. (Version 12.2(4)T)
This is so old that it is not even listed anymore. For more information, refer to:
Cisco IOS Software Product Bulletin no. 2863
Cisco IOS Software Retirement Table
This is the link:
The fact that it is an early T-version makes it an even more more likely suspect. Unless you are 200% certain that this IOS version is performing fine elsewhere with a similar config, I would suggest that you begin with upgrading the router to some GD version from the list.

Just to let you know that upon revisiting the trouble shooting documentation I have found the resolution. I have changed the console logging level to critical.
I have a project in place to update the IOS levels on all the routers that we use.
Thanks for your help.

Best practices tell you to actually turn off logging console . Only turn it on if you need it to look at something and you are attached to the console , other wise there is no reason to have it on .

For the future : here is a nice command to help you isolate which processes are using CPU:
show process cpu | exclude [0-9.]+% +0.00%
