jrun cpu utilization maxed at 100%

[periker]

This has happened before and rebooting and fixed the problem.

I have 5 web server load balanced. SQL Server 2005 on the back end. None of
the other nodes have issues. All are running CF 7.0.1.

The processor utilization started to spike at around 9am this morning. The
exception log has this entry several times in it:

"Error","jrpp-114","01/31/07","07:55:40","registration_mywebsite_com","You

Any ideas of the problem? Good troubleshooting steps?

Periker,

Not to try to sound "funny", but the specific code that is causing the problem
is in these error messages:

"The specific sequence ..."
D:\web_roots\registration.mywebsite.com\design\def ault\dsp_js.cfm, line: 82

Can you look at dsp_js.cfm, and let me know what's there (on line 82)?
