Summary :
This SAP Note addresses an issue where call disconnections are logged in syslogs due to CPIC and TCP/IP connection errors. Errors are tracked by the RD (reader daemon) and BTC (batch session) components indicating failed operating system calls (recv error no. 10054) and CPI-C connection closure. To resolve the issue, the note recommends setting the gw/gw_disconnect parameter to 0, ensuring that TCP/IP connections remain open. This solution is applicable for specific SAP kernel versions (620, 610, and 46D) detailed in the note, guaranteeing the termination errors are permanently resolved from these patch levels.
