Grapviz is unable to manage very big plots normally, and crashes in this situation with a similar error message. This software does lots and lots of calculus repeatedly eating a lot of memory.

The binary is /usr/bin/dot

Ok, enough, wrong option. If your plot has more than 100 nodes try instead, sfdp
