This system has 4 GB RAM but only a 2 GB swap partition. Was this just

Yes and no.

Hibernate will compress memory image before storing it to the swap, so
depending on what was in the memory and how good is compression ratio it
may, or may not fit to available disk space. Some file types, and gaps
with no valid content, is possible to compress better then memory with
a lot of valid content that is already encrypted, or has files that
have poor compression ratio.

Obviously, it works fine for majority of people, as we can't see massive
complains, but taking how cheap is disk space, having large swap as in
1.5xRAM_size is a safe bet.
