Saving YAP's state

[Pablo Beltran]

Hi,

I'm trying to save the YAP's state:

====================================================================================
  ?- open('x','write',F),save_program(F).
     ERROR at  clause 3 of prolog:save_program/1 !!
     SYSTEM ERROR- restore/1: address space has holes of size -524288, cannot save
====================================================================================

Am I doing things right?

best regards,
Pablo

PS: I'm trying to save YAP's state after loading 700Mb of data (+8 million of facts). Yap 5.1.4 is running on the Ubuntu 8.10.

Perhaps because you are passing save_program/1 a stream when it wants a filename.

save_program(+F)

Saves an image of the current state of the YAP database in file F.

Hope that helps,

Parker

I have checked and found that using a large -h value to prevent holes
and an atomic  filename in the save_program works fine. Tony
