Hi Sudheer,
Could you confirm the instance number of your system as per attached parameter files found
| icm/server_port_0 | "PROT=HTTP,PORT=8000,TIMEOUT=120,PROCTIMEOUT=180" |
This parameter plays a vital role for http requests.If possible try to set the parameter value with PROT=HTTP,PORT=80$$,TIMEOUT=600,PROCTIMEOUT=6000
Then second parameter you need to check is
| SAPSYSTEM | 0 |
In log file showing value 0,either it should be 00 or as per your configurations.
Third is to maintain parameter icm/host_name_full with FQDN in instance profile and check again after restart of the server.
Regards,
Gaurav
