suitesparse - What does "CHOLMOD error: out of memory" mean?

Question

I am trying to compute the QR decomposition of a large but very sparse matrix (1000000x100000) with sparseqr python package. I receive the error

CHOLMOD error: out of memory. file: ../Core/cholmod_memory.c.

RAM doesn't seem to fill up during the computation, so I am wondering what the error means exactly.
