First I would like to say that re-creating the ID file because of expiration is not a good idea. This can cause many security problems, especially if the user is using any form of encryption. You can still manually recertify an expired ID file by using the Cert ID from the Administrators console.
Secondly, it is difficult to know without more information what is happening with your ID vault. You can troubleshoot by enabling the following debug parameters:
- DEBUG_IDV_CONNECT=1
- DEBUG_IDV_TRUSTCERT=1
- DEBUG_IDV_UPDATE=1
You should also open a PMR to get definitive assistance with this issue.
