Server with large drive, FIle List timeout

One of the backup clients has a 20TB drive with maybe 10TB on it. When the full File backup gets to listing the files, it always timeout… Is there anyway to increase this “file list” timeout threshold?
Using the latest version of server and client.

The timeout should be high enough. Could you provide a server debug log file?
