I have spawn up an instance of SAP S/4HANA 2021 FPS02, Fully-Activated Appliance from SAP Internal CAL in AWS in mid-September. This instance is only activated for business hour by a weekly schedule in CAL console. It was working fine until after the New Year break. Starting Jan 11, users reported not able to connect via SAPGui. Upon checking with sapcontrol. Observed that Dispatcher gone into a Stopped state after every CAL activation. There's no change has been made since September. I wonder what might be causing this issue.
Under sapcontrol, nr 01 appears to be healthy. Here's the output of nr 00:
sid-hdb-s4h:s4hadm 52> sapcontrol -nr 00 -function GetProcessList 16.01.2023 15:07:13 GetProcessList OK name, description, dispstatus, textstatus, starttime, elapsedtime, pid disp+work, Dispatcher, GRAY, Stopped, , , 10074 igswd_mt, IGS Watchdog, GREEN, Running, 2023 01 16 13:45:03, 1:22:10, 10075
Here's the dev_disp file grep output with string 'server'
