Error is srt_util log "No configuration for binding key"

Dear Experts,

My scenario is basically a PI to CRM synchronious service configured using WS adapter. We released a CR to production in the morning and after that my service calls are failing in PI with the below message when seen in srt_util:

"No configuration for binding key xxxxxx"

We have checked the following from our end:

PI: All sender and receiver wsdl configurations have been check for any error.

CRM: Proxy has been tested locally and it is working fine. All SOAMANAGER settings have also been checked.

Any further pointers in resolving this issue will be appreciated since since has caused a huge prod impact.

Warm Regards,

Anshul
