CF8 - 100% CPU usage

We regularly encounter performance issues with ColdFusion 8.

On a farm of 3 front end servers, one gets unavailable: for some reason, the CPU goes 100% (on one core) and never goes down. When checking on Windows task manager, it appears the the jrun process is using 100% of on CPU.

do someone have a clue on how to start troubleshooting that? How to figure out what's cuasing the spike in first place.

Our configuration is currently:

CF 8 running on Windows 2008 R2 64 bits with Oracle 11g client, with 4GB RAM and a dual core CPU.

Check your http logs to see what pages were requested.  When this has happened to us, it's almost always caused by:

1.  a slow query

2.  user re-submits request before results come back.

repeat as necessary.

Suggest check for errors & warnings in ColdFusion8\runtime\logs coldfusion-event coldfusion-out log files.

Case multiserver enterprise licence logs in Jrun4\logs.

HTH, Carl.
