A tricky component(?) message processing exception

[former_member560382]

Hi guys,

we have a very strange exception on messages being processed on our PI system. Have you ever gone through this please?

A hint might be, the messages are sometimes processed OK, but sometimes thay fail on this exception. It really seems to be a random behaviour.

Any help appreciated.

Peter

Hi Peter,

What is the Scenario / Message flow here? Is it happening for any specific Interface / Adapter? Is it for Dev or Prod system issue

What is your PI version?

Hi Azhar,

this is a SOAP->PI7.31(single Java stack)->Proxy.. but there are also different interfaces which fail and as I mentioned - the failure doesn't have any pattern, it just seems to be random.

Thanks,

Peter

Hi Peter,

Please check if the OSS Note # 1827196 is helpful in your case...it has similar error message stated in it.

Hi Azhar,

we have restarted the system and so far it seems to be working w/o any other change, so will see.

Anyways, thanks for the effort.

I have no idea why - but it worked for me as well. I was very sceptical ..
