Getting SWIFT internal error:bad call of realloc:Failed to allocate block

I am using following commands to save a checkpoint and later on wanted to restore it in order to create a snapshot,Commands used are

ncsim>stop -object test.active 

ncsim>run

ncsim>run -clean

ncsim>save -overwrite worklib.first_snap

ncsim>run 2000ns

ncsim>restore first_snap

After the "save -overwrite worklib.first_snap" command got the below mentioned error.

Message!     [SDI/Verilog]                                                    
    SDI/Verilog does not support save - no SDI information will be saved.

SWIFT internal error: bad call to realloc: Failed to allocate block: Size 188978564442, SaveRestore.c, Line 1340
File 'SaveRestore.c', Line 1340

Can anyone please help in getting this issue resolved or is there any other alternative way for saving and restoring checkpoint.

Thanks,
