CALL_FUNCTION_REMOTE_ERROR "connection closed (no data)"

Hi Friends,

Need your help in this peculiar kind of situation in which an RFC call from SCM system to R3 system is ending in dump with run time error CALL_FUNCTION_REMOTE_ERROR "connection closed (no data)".

The dump log in SCM system says "The error occurred during an RFC call to another system.In the target system, a short dump has been written as well.More detailed information on the error cause can be found there."

But when I check in R3 system there is no dump. I even tried to debug it but control never reaches to function module it terminates before that.

I checked SM21 in R3 and found this.

"Delete session 001 after error 052". Don't know what error 052 is.

I have attached the dump log.

The most peculiar thing is same RFC runs fine after an hour but only at a particular time interval it fails with the reason mentioned.

I raised to SAP as well they gave their famous reply that this is a custom object we can not help there.
