Bad server had $AUTOSYS/bin/wrapper with Nov 29 2020 time stamp. Another server where it works fine, had one dated Sep 2023
In this specific situation, during upgrade, a custom monitoring program was restarting the webserver when it was supposed to have been shutdown for upgrade. This left the wrapper in use, there by the file did not get replaced during the upgrade.
Copy $AUTOSYS/bin/wrapper from good server to bad one and restart webserver service.
