MarkLogic keeps crushing when I try to run cts.train() function


MarkLogic keeps crushing when I try to run cts.train() function.
Is it my code or something else? Can you help me figure out what's wrong?
MarkLogic Server 8.0-6.4
var labels = []
var voi = cts.collectionQuery(["VehicleOfInterest"])
for(var v in voi)
labels.push({classes:{name:"car"}})
v = cts.search(voi)
var all = [].concat.apply([], [v.toArray()])
var classifier = cts.train( all, labels, {classifierType: "supports", kernel:"simple", epsilon: 0.01} );
