Service Unavailable - Default App Pool is being Disabled

I've search the site for an answer and I can't narrow the result down to the problem I'm having.  This is urgent because it stop my users from checking their email through RPC/HTTP and OWA.

The DefaultAppPool is being automatically disable.  I restart the WWW Publishing service and all is well for an undetermined period of time (the last time I had to restart it was on 6/5/06.)  

The event log reveals the following,  Event ID 1011, Source: W3SVC, A process serving application pool 'DefaultAppPool' suffered a fatal communication error... The process id was '4768'. The data field contained the error number.

Also, the same Event ID of 1011 is seen again with a process id of '804', '1996', '7148' & '5448'.

Then an Event ID 1009, Source: W3SVC, A process serving application pool 'DefaultAppPool' terminated unexpectedly.  The process id was '3188'.  The process exit code was '0xc0000005'.

Finally an Event ID of 1002, Source: W3SVC, Application pool 'DefaultAppPool' is being automatically disabled due to a series of failures in the process(es) serving that application pool.

Previous events are close to the same as described above, Event IDs of 1011, then Event ID 1009 and then the 1002 where the Default App Pool is disabled.

Hi  Mitchl33,

Can you please provide more details on what applications are being served in 'Default Application Pool'?

Normally, crash of an application pool is related to malfunctioning application in the pool.

TJ_TJ,

Thank you very much for your question, I was beginning to think that it was hopeless to post the question.

I have limited experience with IIS, how do I find out what applications are being served?

This box is an Exchange Front-end server (Exchange 2003) and allows OWA.  It seems the problem may have occurred after upgrading Symantec Mail Security for Exchange or the Symantec client but, I don't know how to prove that Symantec is causing the problem.  Any help would be greatly appreciated.

Thanks again,
Mitch

Hello Mitch,

I've no hands-on Exchange, but I'll still try to get some pointers on the issue described.

I'm assuming your application has been setup on Windows Server 2003 and IIS 6.0.

Open IIS Management console (use Start-->Run and type inetmgr)
Browse to Application Pool and locate 'Defaul App Pool'. Double click on the Default App Pool and on the right pane you'll see list of applications. These are the applications which are residing in Default App Pool.

As a best practice, keep your different applications in separate App Pools. In IIS 6.0 you can create multiple App Pools and can host multiple applications in them.

TJ,

Thanks for your time and attention.

Your assumtions are correct, it is a 2K3 server w/ IIS 6.  When I perform the steps as suggested, there is nothing listed under the DefaultAppPool except for Default Application and there are no items to show.

I do have multiple App Pools, two for Exchange and one for Symantec Mail Security.

I posted this question on 6/8 and I didn't see the problem again until yesterday and as mentioned above, the fix is to restart the World Wide Web Publishing service.

Thanks,
Mitch
