Not sure when this bug started, but at some point, as.matrix() started being called on the DocumentTermMatrix, which materializes it.
At any rate, R can't create a matrix with >2 billion entries. So, the 200000*100000 (20b) entry matrix can't be materialized, even if it could fit into memory on my machine. Why this problem hasn't come up before, I have no idea.
At any rate, looking at the kmeans code, it probably makes most sense to overload the as.matrix method for DocumentTermMatrixes or as.matrix.simple_triplet_matrix so that it just returns itself - or, find an implementation of kmeans that will work fine on large, sparse, matrices.
