[Bonmin] cplex runs out of memory

Hi,

I'm solving a number of MINLP problems in GAMS with Bonmin using the  
OA method with CPLEX because it's proving to be the fastest method.  
However, in some instances I'm getting the following error:

CPX0000  Warning: MIP starts not constructed because of out-of-memory status.
CPX0000
CPX0000  Consider using CPLEX node files to reduce memory usage.
CPX0000  CPLEX Error  1001: Out of memory.

Is there any way to pass options to CPLEX through Bonmin so that I can  
give more memory to CPLEX, or to reduce memory usage?

Regards,
Juan
