CFMX Hanging

[capesong]

We are running CFMX 7.0.1. The CF server is hanging about once a day now. Most
of our business takes place between 9 - 5 M - F and we almost always get hangs
during those hours. The server almost never hangs on weekends or at night.
During the hang CPU for the CF process spikes to about 50% utilization, where
it normally runs at 10%. The server even hangs on a normal stop command so that
we have to kill -9 the jrun processes to get it restarted.

Looking into the CF server logs there is no regular pattern to the errors and
the errors don't seem that serious to begin with.

We run 7.0.1 on a Solaris 2.8 machine, specifically a Sun-Fire-280R, with 8
gigs of memory. The CF server communicates with Apache 1.3.36 on the front end
and almost exclusively with Oracle database servers on the backend.

Does anyone have any advice for these hangs? What can I look at? Help!!

See [url]http://www.adobe.com/cfusion/knowledgebase/index.cfm?id=tn_18772[/url]. The two
things from the article that should help you investigate the hanging condition
are enabling metrics and running stack traces at the time of the hang.

I had similar problem. I did following.

0. Install CF7 patch till 7.0.2

A. Tune up JVM
Try installing JavaSDK from [url]http://developers.sun.com/downloads/top.jsp[/url] (It
should version 1.4.13 or new. Install in webserver.

Back up runtime\servers\coldfusion\SERVER-INF\jrun.xml

Goto CF admin, change JVM path to new java installed folder.
restart cf services...

It will help for any JVM memeory leaking and loads.

B. Tune up CF pages.
Check any pages which returns large query, then use paging

C. Tune up DB Query
Use store procedure.
