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
https://issues.apache.org/bugzilla/show_bug.cgi?id=48826.
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
