Troubleshooting Random null null Error in Coldfusion MX

I have been looking so much for this error in Coldfusion MXÂ but could not find any solution to my problem. null null is a very vague exception error which gets thrown once in a while. Below are the steps I did to troubleshoot and one of them did the solved the problem.

 1) Apply this hot fix from Adobe.

2) Increase the JVM Heap Size. (I increased it  from 512 to 800)

3) Make sure your SELECT query does not pass any corrupt data. It might also be the very cause to  throw the exception error.Turning off query caching signifigantly increased the number of errors, so it seems to be something in the JDBC drivers.

4) Check to see if you have methods that accept parameters passed by reference(like getimagesize()) . Make sure you use right script language for example getimagesize uses VBSCRIPT not JSCRIPT. ( For me this was the case. I removed this method and it stopped the error completely).

Windows Vista Release Candidate 1 is Now Available

I just Recieved this email from Microsoft. Thought would share with you guys !

Just to inform you that the final major pre-release of Windows Vista – Release Candidate 1 (RC1) – is now available for download for CPP participants. Please use the links below to access the download site, and install this release as soon as possible. (If you ordered a DVD kit for Beta 2 you will receive a new DVD kit containing RC1 in approximately 2-4 weeks.)

Important Information about Windows Vista RC1 . We remind you that RC1 is pre-release software and you should not run this on production or mission-critical PCs. Support will be limited to newsgroups, and you may have to do a clean install to move from this release to the final release of Windows Vista.

. You may upgrade an existing installation of Windows Vista Beta 2 or Windows XP to this release. However you will have to do a clean install if you want to get back to a previous configuration.

. Before upgrading from Beta 2 to RC1, please install any Critical Updates from Windows Update for Beta 2. Go to Start, All Programs, Windows Update, and click the “Check for Updates” button.

. Please close any open applications before beginning an upgrade. During installation we recommend you have an active Internet connection and choose to “Go online to get the latest updates for installation.”

. Installing RC1 requires a valid Microsoft Product Key. You should use the same Product Key that was provided to you (and sent in email) when you registered for Beta 2 in June. For your convenience, your Product Key is included here:
“XXXXXX”

. Due to the size of the download we recommend you use the download manager provided as it will allow you to resume the download if your Internet connection is interrupted during the process.

. As with Beta 2, the download for RC1 is an ISO file. After you complete the download you will need to burn a DVD to install RC1. For more information, including DVD-burning instructions, program information, and feedback links, please refer to the Customer Preview Program start page.

. To help you explore Windows Vista, we have created a list of tasks for you to try. To access the list and provide feedback on your experience, visit the Windows Vista Scenario Voting site. Windows Vista Scenario Voting
