double array allocation of sink - Forum - Delft3D

Hi, I'm running a 3d model and this error occurs:

*** MESSAGE Executable for 32-bits platform. 
*** MESSAGE Double precision computation using reals of kind    8 
 *** ERROR in double array allocation of sink  
           Contact Deltares
*** ERROR Flow exited abnormally 
 

What that means and how to fix?  

Thanks.
