PST migrations stop with the prompt "Press any key to continue". Pressing the key continues to the next account, followed by the same message.
Ensure you are using the "Zimbra Exchange Migration Tool", and not the deprecated "PST Migration Tool."

ZimbraMigrationConsole <xmlpath> Silent=true
This will suppress the error messages, and the migration will now continue without any error.
