disp+work, Dispatcher, GRAY, Stopped - SAP S/4HANA 2021 FPS02 Fully-Activated Appliance

[eddy_guo3]

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

Here's the dev_disp file grep output with string 'server'

Hi Eddy,

please check the license of the HANA DB (see Getting Started guide chapter 3), and following the S/4 license in SLICENSE.

The temporary license key expires after 90 days and needs to be replaced by - in your case - an SAP-internal license key. That would fit to the timeline you mentioned, feel free to contact me in case of questions.

Best, Joerg

Hi there,

I have the same issue. My SAP Instance was working fine, after a restart, I could not restart the dispatch service no matter what I did.
I receive the following error:
