The usual method of hibernating is to dump the memory into the swap partition. I do not know what will happen if your swap partition is smaller than your RAM, though.
Wolfgang Pfeiffer:
32 GB of RAM here, swap space is just ~16 GB: my guess is that as long as the totally used memory (including buffers/cache) isn't bigger than the swap partition, some hibernation image might be written successfully ... not being sure, tho' ...
I believe it can also use a swap file, so you can add one to a partition with space. However, when there's more than one swap, I think you need to set a kernel parameter for the system to look in the right place for its resuming data.
And swap space is rarely used here, IIRC ..
Generally speaking, the same here. But when I had a system with less RAM, web browsers were terrible at wasting RAM. If you had enough tabs open, or hit a badly coded website, the system would start paging and never recover unless I managed to kill the web browser. Often I couldn't, because the system was so unresponsive you couldn't use the mouse or keyboard.
