[Question]: Azure DevOps Agent Service vs SMS Agent Host Service

[hedasp]

Describe your question

When upgrading the Agent Service to newer version on deployment target group, we faced an issue where ccmexec(SMS Agent Host Service) process was holding files in /externals folder even after Agent Service was stopped.
typically files in /externals/tf/ and /externals/git/
Any insight on what these processes are and how to make sure they finish in time for the self-upgrade script to run successfully?
As long as the process was active, the script couldn't rename/move the externals folder.
Also, to re-run the _update.cmd script, we had to rename the /bin folder from versioned to just bin again.
