Hmm. My naive guess is that either the Rust server is interpreting the
list/string length incorrectly and just allocating memory for an absurd number
of elements. We’d have to see if the client is generating properly encoded data
or if the Rust server has incorrect decoding.
Either way the Rust server/client implementations should have some max memory
bound. I should have included that.
