Why would this be true? gmetric strings that are longer than 32 bytes work and
have for a long time. In the wire encoding, xdr_string encodes a length
followed by a set of octets. The old (<3.1) protocol.x says that all the gmond
metric strings are xdr_strings.
We use them, e.g., to encode the (full-path) versions of our various gmetric
scripts. Those are almost always longer than 32B.

I would have to verify this, but I think making MAX_G_STRING_SIZE larger would
affect the XDR packets. Any change to the XDR packets would cause gmond to be
incompatible with previous versions. It would probably have to wait for the
next major Ganglia release.
