Hi,

I have some inbound/outbound ports that were working nicely in an installation for along 1 year...and suddenly it have stopped to work. Outbound messages are not processed in the queue and text files for my Inbound Port are not readed...

I have tried to activate/deactivate the ports, redeploy AIF services, compile CIL all, restart everything...but nothing seems to work.

Any ideas of what could happen?

Thanks

You have to collect more information - the first place to look is System administration > Periodic > Services and Application Integration Framework > Exceptions. The next is the Troubleshooting section on individual ports.

If everything fails, you can always step through the code in debugger (and activate tracing for WCF code).

Unless you know what's the problem, it's hard to fix it.

At System administration > Periodic > Services and Application Integration Framework > Exceptions there is nothing new because basically it does nothing so I will try to debug the code.

Thanks

At the moment I think I get an error with the call to

AifUtil::getServerTempFileName

At Table AifGatewayQueue, method getGatewayMessage ->

if (isTransformRequired) // Preprocessing is required

{

filePath = AifUtil::getServerTempFileName();

...

I found it!

It seems that this function fails when there is more than 65535 temporal files in the %TEMP% folder (In my case was in the temporal folder of the user which I had asigned to run the AOS service)

I'm glad you resolved the problem - and thank you for letting us know!

I wouldn't ever thing about this reason - it's exactly one of things that don't make much sense until the problems is isolated.

That GetTempFileName() doesn't support more than 65535 files is documented behavior and IOException is thrown when it happens. If the exception reached you, the problem would be quite obvious from the beginning. The problem here is likely that Exception::CLRError is not handled and it unfortunately means that the execution is interrupted but you don't get any error message or anything. This is very dangerous behavior of .NET Interop - I see developers making this mistake and again and I also already ran into the same problem in the standard AX codebase.

Ok. I got an exception with Outbound Ports with the message "File already exists". But nothing more. At first I supposed that somewhat temporal file would be created with a name that already exists but the final reason was something else.

Thanks for taking the time to think about this problem.
