SOM for VB3 don't have the code to connect or administer DB connection too. There's some other problem or a combinations of a few. SOM talks a lot to remote servers & cURL library may slow the scripts down (if remote servers are slow to response). If this is the case - you need to set lower cURL wait for response timeout. Another possible case - VB is setup to use permanent connections or normal connections, but long auto-close timeout. This all needs to be checked and tested. I think you hoster is right - some developer need to have a look.
