Getting ERROR when I try to save and restore waveform.

When I try to save a checkpoint, so that I can restore it later.

But when I try the below command,

ncsim> save checkpoint_1

I am getting the below error,

Message!     [SDI/Verilog]                                                    

   SDI/Verilog does not support save - no SDI information will be saved.

Current simulation time = 0                                                                        

   "/tools/cadence/INCISIV121/tools/uvm/uvm_lib/additions/sv/cdns_recording.svh", 75: $sdi_create_fiber(name,t,scope);

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 me resolve this issue.
