Update to ColdFusion 9.0.1 : Cumulative Hot fix 2 from Cumulative Hot fix 1 maxed CPU

[david_alonzo]

We have 5 load balanced web servers and we updated two of them to ColdFusion 9.0.1 : Cumulative Hot fix 2 and Coldfusion Security Hotfix APSB11-29 from ColdFusion 9.0.1 : Cumulative Hot fix 1.  When the two servers hit heavy load, the CPU maxed out and brought CF to a halt on those machines.  In the C:\ColdFusion9\runtime\logs there are timeouts in the logs waiting for an available thread to run.

These time outs continuted on until the service was restarted.  Has anyone experienced this when they updated to CHF02?

[BKBK]

I am not at all surprised. There is no such thing as an update from Cumulative Hot fix 1 to Cumulative Hot fix 2!

The rule is, apply only one cumulative update at a time, normally the most recent one. It's all in the word "cumulative". Cumulative Hot fix 2 includes all of CHF1.

My advice is that you should uninstall both CHF1 and CHF2, restart ColdFusion, then re-install CHF02. However, be aware that uninstalling these hot fixes could be quite intricate. They involve updating a large number of ColdFusion's system files.

If you had followed the respective installation instructions for Cumulative Hotfix 1 and Cumulative Hotfix 2, then uninstalling should be straightforward. You will find the instructions at the bottom of those pages.
