sap note 559199
Summary
Symptom
Call disconnections are recorded in the syslog or dev_rd.In the syslog these appear as follows.The entries are written by the gateway reader:
19:00:24 nefssp24_PRD_00 RD DDIC
#Q0I Operating system call recv failed (error no. 10054)
19:00:24 nefssp24_PRD_00 RD DDIC
#S23 Connection to CPI-C client 218 was closed
19:00:24 nefssp24_PRD_00 RD DDIC

Other terms
Gateway 223 Q01 setup connection
Reason and Prerequisites
Using parameter gw/gw_disconnect, a gateway closes the TCP/IP connection between two gateways if this is not used for a specified period.The error occurs if the client side wants to restart an RFC connection but the server side deletes the TCP/IP connection.
Warning:
The error occurs extremely rarely - you can almost always retrace the above error message back to the errors described in note 516027.
Solution
Temporary workaround:Set the gw/gw_disconnect parameter to 0. Connections are no longer broken, so terminations are no longer possible.The error is definitely eliminated at the following patch levels:
620: 380
610: 610
46D: 1293
The function allowing connections between two gateways that have not been used for a long time to be closed is only available as of Kernel Release 46D. Therefore, corrections do not exist for lower kernel releases either. |
