32-bit Software & 64-bit hardware Compatibility

We have install Coldfusion MX 7.0.2 on a 64-bit Xeon Duo-Core Intel server running Windows 2003 32-bit Server. Is this OK or are there issues running 32-bit OS and Coldfusion MX 7 on a 64-bit machine?? We are experiencing Coldfusion "freezes" or hangs. The problem goes away when the server is restarted or the Coldfusion service is restarted. Our web developers suggest a corrupt OS so I was going to buy another server but can only find 64-bit processors. Is the 32-bit OS, 32-bit Java and 32-bit Coldfusion MX 7 running on a 64-bit hardware causing my problem??? I don't want to buy a new 64-bit machine to have the same issue. We are a K-12 public school with limited resources.... the $499.00 fee to ask Adobe this question is hard to swallow! Thank You!

There are many forum threads that discuss coldfusion hangs. There are also many technotes that discuss troubleshooting of these. Start by reviewing them.

To begin with review your cfusionmx7\logs and cfusionmx7\runtime\logs. Initially review your application logs. Fix the errors there and in the exception log. You may want to archive all existing logs and start with clean logs. Next time you hang look to see what kinds of errors you are seeing at the end of the log.

Thread dumps are a typical troubleshooting tool for hangs. Review the technotes on these.

Unless there are other obvious signs of a problem with your OS, there is no reason to suspect it. Coldfusion 32 bit runs fine on 64 bit hardware.

I'll second (or third?) the OS as being the culprit. We have multi-instance CF 7.0.2 running on multiple 64-bit servers using 32-bit Windows Server 2003 without any problems.

However if you can afford the upgrade, a 64-bit version of CF8 is on the horizon.

You have a 32bit OS and the OS is important and CF works without any problem on a 64bit hardware with a 32bit OS.

There must be something different as a problem.

In your case, I would prefer to reinstall OS as clean and test it again.
