Coldfusion service stops responding

Question

We have a BIG problem on our Coldfusion production server.
Today is stopped responding on requests. It has been more and
more frequent lately.
Server info:
ColdFusion MX
Version: 7,0,1,116466
Edition: Standard
Operating System: Windows 2003
Java Version: 1.4.2_05
Usually we can’t find anything in the log files but
today we did get this:
Component Prog ID: 3[ODBC][Env 2fc1978]
Method Name: IDispenserDriver::CreateResource
Process Name: w3wp.exe
Exception: C0000005
Address: 0x7C8224B2
Call Stack:
+ 0x7c8224b2
+ 0x40280006
Faulting application w3wp.exe, version 6.0.3790.1830,
faulting module ntdll.dll, version 5.2.3790.1830, fault address
0x000224b2.
Any idea’s? Any one that would know how to
debug/monitor this?

Answer 1

That sounds like a problem with IIS, rather than ColdFusion.
In which log did you find this error - in the system event log?
One thing that might help, install the IIS Diagnostics
Toolkit (iisdiag):

You can use the debugger to capture detailed crash dumps and
run analysis reports that can usually point you to the source of
the problem.
Another thought, I've heard of people running into issues
with Windows 2003 server where the OS itself is at Service Pack 1
(or 2), and IIS was installed from an older binary (e.g...the
original Windows 2003 installation CD). That can sometimes create
strange IIS issues, as described here:

Best of luck with it.
