Server Logs Errors

For the past week, we keep getting this error 4 times per second :

[13/03/07@15:59:53.412-0800] P-006948 T-007696 1 AS -- (Procedure: 'laborDtlAfterGetRows Server/bo/Labor/Labor.p' Line:41759) ** Value 21330 cannot be displayed using >9.99. (74)

Does anyone know what is causing it?
