Hi All,
We are facing ine issue in daily P2P load from SRM system to BW system. Many tRFCs are getting stuck red with message "Error when opening RFC connection". In SM21; we can see below error logs:
RD Q0 I Operating system call recv failed (error no. 104 )
RD Q0 R Call of function GwRead failed, RC: -006
DIA 016 100 ALEREMOTE E0 0 New System Log File Started with Number 18
DIA 016 100 ALEREMOTE R4 9 Communication error, CPIC return code 017, SAP return code 239
DIA 016 100 ALEREMOTE R6 4 > CPI-C function: CMINIT(SAP)
When I checked the RFC connection from SRM to BW system. It is behaving strangely. In 3,4 connections tests. It works fine. Then fails for next two with SAP gateway communication error. The local gateway is running. But sometimes it gives same error in SM58 that Local gateway not running. Below is the gateway trace

The temporary behaviour of problem is strange. The RFC starts working fine always once teh load is finished. No more errors in SM21 as well.
Could you please help me on this issue.
Thank You
