Comparison - Connection Reset Error

I am seeing a problem when attempting to compare content items on my production sever, however the problem does not exist within my testing server. I have tried comparing content items in various communities and using various content types. The following is how I am testing this function:

[li]Right-click a content item
[/li][li]Select View > Compare
[/li][li]Select the revision for both instances to compare
[/li][li]Click the middle tab labeled ‘Compare’

After completing the last step, the server waits about 1 minute and displays ‘Connection Reset’ where the comparison data should be displayed. Does this tool use something that could have not been enabled in my production environment?
