MID size limit?

2012-07-17 15:49:23|10809.7|  0.3|ERROR |MIF Writer: The MID file for 'E:\\7-travail\\FME_TEMP\\travail_fusion_nationale\\résultat\\A_RESEAU_ROUTIER\\ROUTE.mif' exceeds the 2GB size limit. Please reduce the volume of data written to this dataset, or subdivide the data across multiple files

 

 

So FME do not accept MID more than 2 Gb?

 

 

I don't understand because last year we received MID  of 3Gb!?

 

 

thanks
