Error: select sum(filesize) from LRUCache

System

Does anyone know what this means? Looks like a conversion or something is failing. I found it in the mbp.log.

09/20/05 13:21:45 Error with SQL: select sum(filesize) from LRUCache where path = ?
09/20/05 13:21:45 Arithmetic overflow error converting expression to data type int.

Thanks!
