JCO_ERROR_COMMUNICATION: CPIC-CALL: CMRCV on convId: 02667299

Question

Hi Experts,
I am having some issue with PO and ECC connectivity with data load from PO to ECC system via RFC connection
RFC is configured in PO , SOA -> Technical Configuration -> System Connections -> Provider Systems -> Connectivity  as below
from NW 731 PO system  sending data to ECC system via RFC  connection  getting the following error
We are getting this error sporadically,  
Do I have to do anything with the  SLMG log on group for this RFC connection ?
Detail log is attached  too as file attachment

Answer 1

Hi Imtiaz,
Thanks again for your reply.
gw/cpic_timeout is dynamic and I have increased to 40 from 20 , and gw/max_conn is already set to 4000.
To isolate the problem,  I have also removed load balancing with  the connection, now directly with CI only. This is  production, so I  have to wait till next data load.
I will update with the result
Thanks
Al Mamun
