I know, I would have expected that, too. I did a bunch of tarp/sail connection tensile tests and the failure was always about 6" from the connection. When I disassembled the knot on the hammock (actually a sheet bend), there was considerable deformation at the bend.
This failure may have been a weakening due to folding for storage over winter.
