CF Server hangs every few days

Question

Every couple of days, ranging from 1 day to 2 weeks, we get
an application that hangs when trying to access a page that uses a
database query. I have to manually restart the CF application
server service to correct the problem. I am unsure what is causing
this.
My Server.log shows multiple entries of the same error
message, but reported in 30 second intervals (which I believe is
due to the option in CF administrator "Timeout Requests after (
seconds ) [30]" )
Here is one line of the Server.log, and this line repeats
over and over in close to 30 second intervals:
"Warning","jrpp-206","02/23/07","13:51:36",,"Thread:
jrpp-206, processing template:
C:\Inetpub\wwwroot\CFMX7\tagout\login.cfm, completed in 30 seconds,
exceeding the 30 second warning limit"
this error message continued through "completed in 1009
seconds" before I restarted the CF service.
When I restart the server, is all back to normal. Sometimes
it can go only a few days before hanging, sometimes up to 2 weeks.
But rarely longer than 2 weeks without a hang.
I have read the "ColdFusion MX Hanging Condition
Investigation" thread, but I didn't get much help from it. I
couldn't tell if my problem was either of the cases described. So
I've come here hoping that someone has the answer! :)

If you are running on MS Access, be sure to disable "Maintain
Connections".
You will also likely benefit by using the Jadozoom JDBC
Driver instead of the native ODBC drivers.

If you are using an enterprise database with JDBC support,
you may benefit by updating to the 3.5 JDBC drivers:
