I am using Coldfusion 11 Standard Update 4 on a VMware virtual server with Windows Server 2012 Datacenter.
We are having a problem where pages using <cfspreadsheet> or <cfdocument format = pdf> stop responding. Web browser just sits there loading page. All other pages seem to be working just fine. This has been going on for several months.
Sometimes I can restart the CF Application from 'services' and it starts working again. Most of the times I have to reboot entire server. Sometimes several times before it starts working again. It may work for days or just a few minutes before I have to reboot again.
I can't figure out what's causing it, or how those 2 tags are related. As I said, all other CF pages work just fine.
Thanks for any help.
