For several day/months I was trying to find solution for hibernation during high RAM usage on my laptop - Toshiba Satellite L50-B-1K6. I am facing similar issues on my desktop PC.
My hardware configuration is:

Available RAM memory is 4 GB. SWAP partition is 9 GB.
Hibernation mostly depends on your HW config (my mistake was buying Toshiba of course) and kernel version.
My current kernel version is:
I had similar problems with older kernel versions (4.1, 4.4, 4.6, ...) also.
Tried various hibernation methods with no luck:
$ systemctl hibernate $ sudo sh -c "echo disk > /sys/power/state" $ pm-hibernate $ s2disk - TuxOnIce kernel
Problem is always similar - hibernate is sucessfull when my RAM usage is low, for example 500MB (12.5 %).
But when I start firefox (or some other high RAM usage program - 50% of RAM) and want to hibernate I am facing following issue.
During resume(thaw), swap space accumulates and hibernation eventually fails - after 3-7 hibernations.
System will hibernate sucessfully, but when I try to turn on laptop it restarts instead of resume(thaw).
Summary: Swap usage is increasing with every hibernation, your machine becomes slow and hibernation eventually fails - restart instead of resume.
I'll post my workaround for this issue, and hope that you will post your tweaks - how you managed to fix this.
