Fusion DB losing Connection

[jko-xcential]

Hello, Our customer who has fusion Db on their server keeps losing connection. Restarting the DB doesn't help It will lose connection again. The first time this happened (last week) we had to rebuild the DB from a back up. This fixed the issue for about a week. Now the DB connection is an issue again. Can you help guide us to why we keep losing connection to the DB?

thanks in advance
