Hi,

My client application is an AspNet site (Web App Project not website). The services normaly run on the same machine for dev, but to investigate this problem a little I am calling the services on a different machine.

So I have an asp.net client application that is calling wcf service on a remote machine.

I have occasional Server Application Unavailable messages in the client application and there is very little information in the event log.

The three error it reports are :

Event Id : 1023

.NET Runtime version 2.0.50727.42 - Fatal Execution Engine Error (7A05E2B3) (80131506)

Event Id : 1000

Faulting application aspnet_wp.exe, version 2.0.50727.42, stamp 4333aece, faulting module mscorwks.dll, version 2.0.50727.42, stamp 4333e7ec, debug 0, fault address 0x0000c539.

Event Id : 1000

aspnet_wp.exe  (PID: 3968) stopped unexpectedly.

 

After the error appears, I refresh the page and everything seems fine.

for some reason,your aspnet_wp.exe is crashing,if you can create memory dump on crash,we may know reasons behind the crash.

Befor debugging more,you can enable tracing on both client side and service side, and check server sent any error messages to client befor crash and clinet is not able to handle this error,that may be triggering client process shutdown

if you have repro,please send it to me,my email id is madhup@microsoft.com

Its intermittent, I have no way to provoke the error.

I won't really be trying to debug it (in a beta), but I thought it worth mentioning here.

The failure does not seem to provoke a dumpprep.exe by itself.

I could turn on all the tracing and then send you the logs after it happens, but that might be a huge amount of data for you to sift through.

I think I have a repro:

I load a page that makes a service request, then I use Clean then Rebuild on the Web Application Project. After that there is strong chance that I get the Servcer Unavailable.

I sent you an email of all the logs, but I didn't see any red in them :S

since we are deploying new dll(after compile),we will raise appdomain exception internally to unload previous dlls,but that should not crash the process.

i got your trace files,but i didn't find any info pointing to this problem in the trace files

I will try to repro the problem the way you explained.

-Thank you

Andrew, just so you know, you are not alone with this error. We are seeing the same thing here:

Still no fix for this.

I still get this problem with the final version of WCF.

All I do is refresh the page until it works Tongue Tied
