Nina discussed with me the issue in POS2NAV of SSI. Advise to restart the application server first and advise the user to try to upload the text file again before we proceed to restart the database server but as per Nina the user is not responding and decided to call it a day. Backup the RGOC database just in case something happens and restart the server. I also run a query in the table in which the process locked when they upload a textfile.
