My rope to the hammock is about the same as yours. I think it's 3/16" from West Marine rated to around 1100 pounds. 3/16" is almost the same as your 5mm (4.76 mm).

Consider the per square inch pressure put on the hammock from a 1" wide strap vs. a 1/8" cord. That's an awful lot of pressure on the hammock fabric from the small diameter cord.
Sounds like the smaller cord is concentrating the stress more than the material can handle.
