This is too general to be able to try and troubleshoot, I'm afraid. You're also using an unsupported version, so you won't be able to get help from Support for this.

Best guess is that this is something pertaining to either the database server or the communications having an issue, but it could also be an issue related to the server itself. With no information available here, there are too many options to try and guess.
