That’s an older post, but for the sake of accuracy, it’s really s.options.numWireBufs.
http://doc.sccode.org/Classes/ServerOptions.html#-numWireBufs
“The maximum number of buffers that are allocated to interconnect unit generators. (Not to be confused with the global sample buffers represented by Buffer.)”
s.options.numBuffers is for the global sample buffers and will have no effect on that error message.
