I get an error message while running my optimization in optistruct.

I am optimizing an explicit model using equivalent static load method (ESLM). This method is integrated into Optistruct therefore one can also perform non-linear optimization.

Although I have enough resources in my computer I am getting an error message #151. It says:

*** ERROR # 151 ***

Error accessing the scratch files:

error encountered in subroutine 'xdslsv'

Solver error no. = -702

index = 1

This may be caused by insufficient disk space or some other

system resource related limitations.

(e.g. The Operating System or NFS cannot handle file size > 2 GB.)

This error was detected in subroutine prepslv4.

and another error message at the end of the out file:

************************************************************************

This error occurs in module 'prpdrv'.

Delete bootstrap file C:/......./CONVERTIBLE_OPTISTRUCT_SUBMODEL1.OS_dump_scr.bin

Can anyone had the similar problem and found the solution? Please help me.
