Problem with database

[gnrx]

Hello.
Since I have installed this mod, I have a problem, I received mails from my forum with this body:

Database error in vBulletin 4.2.3:

This is something that happens randomly on a select few sites. So I have not been able to track down the cause yet.

Ups...
I can made any test for view the issue?

I think this because, this is a problem for me, I received a lot of mails from this issue.

Regards.
