Solution
1. Ensure your SAP gateway is up and running fine. You can check from the OS (UNIX, Linux) level by executing below command.
gwmon pf=<PATH-TO-PROFILE>
ps -ef | grep rd
2. If the gateway is running fine, please check the connection table used via transaction code SMGW (look for the value xx active connection(s) (maximum xxx ). The value xx must be lower than maximum xx. You can also check using below command. The value of connection table is maintained by parameter rdisp/max_comm_entries.
gwmon pf=<PATH-TO-PROFILE>
Gateway monitor, connected to xxxx / sapgwxx Connection table (Used: xxxx, Connected: xxx)
3. If the value xx > maximum value xx. You’ll will have 2 options. For temporary solution, you can kill old connection from the transaction code SMGW or increase the value of parameter rdisp/max_comm_entries for the permanent solution. A restart is needed to apply the parameter changes.
