In which way does it not handle it? Over-allocation is supposed to be handled by the "ctx->restore.tot_pages + sp->count > ctx->restore.max_pages" checks. Do you mean the second 1G is allocated, then max_pages is reached, and allocation in other areas is not possible anymore? Can this actually happen with the available senders? If not, this is again the missing memory map. Olaf
