Either a database issue or a source code issue.
Is there any specific point solutions?
Sadly to say that this is the first time in this section that an error like this was posted. But I do believe its more of a database issue, try asking one of the SQL Nuts here, I'm sure someone here knows. The only thing I would say from this error is a parameter in one of the databases has a value thats either too low, or too high.
Download the source and try to search the error text in the source. It might give you an idea what is wrong.
