Environment

Release : 9.4.3

Cause

This is caused by ntspawn.exe located in the %AW_HOME%\c directory

Resolution

As of 03/15/2022, this issue is under investigation for root cause and permanent fix. This article will be updated once more information or resolution available.

Workaround:
Replace the Windows Agent ntspawn.exe with Applications Manager version 9.3.0's ntspawn.exe attached to this article (need to rename) or if a backup of the %AW_HOME% directory was taken before upgrade, 
replace the ntspawn.exe with the ntspawn.exe from the backup:

1. Rename current %AW_HOME%\c\ntspawn.exe to %AW_HOME%\c\ntspawn.944
2. Move a copy of the ntspawn.930 from this article or ntspawn.exe from backup to the %AW_HOME%\c directory and if needed, rename from ntspawn.930 to ntspawn.exe

The above steps can be done without stopping the Windows Agent.
