gpg-agent connection errors

As part of a server upgrade, we recently replaced a GnuPG 1.4.x installation with GnuPG 2.2.19, from the Gpg4win package (3.1.11). The server is running Windows Server 2016.

We have an un-attended application that runs on that same server that needs to sign+encrypt  a file (4 to 6 distinct files each weekday)for transfer to an external client.

Since the upgrade, invoking gpg to sign+encypt a file periodically fails with the message "gpg: can't connect to the agent: IPC call failed" followed by messages indicating "No agent running". The failure appears to occur on the first file processed (in a group of 3 or more files), and the remaining files are processed without error.

We are relying on gpg to automatically start gpg-agent (as needed). Does gpg-agent auto-terminate after a certain period of inactivity?

Would appreciate any help you can provide that would allow us to eliminate these errors. Thanks.
