Please Help - Randomly HTTP 503 Internal server error

Hi all,

I have a Coldfusion 10 standard Edition installation with MSSQL 2005 on Windows Server 2008 R2 server about 2 week old.

It is one of my live server and it is dealing with medium to high volume of traffic.

Since deploying this server, it has been getting random HTTP 503 internal server errors,

which require the entire server restart (as coldfusion application server, IIS restart will not able

to resolve the problem). Within this two weeks, sometimes it can last for couple of days without problem,

and sometimes it require 4-5 times server restart within one day.

I can't replicate the error on demand, but I could paste one of the windows server event log here:

Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7afa2

Faulting module name: isapi_redirect.dll, version: 1.2.32.0, time stamp: 0x4f745a78

Exception code: 0xc0000005

Fault offset: 0x000000000000cd68

Faulting process id: 0xfd4

Faulting application start time: 0x01cd745ad58e3393

Faulting application path: c:\windows\system32\inetsrv\w3wp.exe

Faulting module path: C:\ColdFusion10\config\wsconfig\1\isapi_redirect.dll

Report Id: 144b3231-e04e-11e1-8e6d-00505687001e

And I started suspecting the problem is because the connector comes with coldfusion 10, based on one of the bug reports from apache

Based on the information in log file, they are pretty similar.

Any suggestions on how to fix this random server error would be greatly appreciated!

Many thanks

Ryan
