Possibly written from a connection with a large msize, and to > be read from a connection with a smaller msize? In that case either the server or client lied about it's msize and is not correctly speaking the 9p protocol. >From version(5): The client suggests a maximum message size, msize, that is the maximum length, in bytes, it will ever generate or ex- pect to receive in a single 9P message. This count includes all 9P protocol data, starting from the size field and ex- tending through the message, but excludes enveloping trans- port protocols. The server responds with its own maximum, msize, which must be less than or equal to the client's value. Thenceforth, both sides of the connection must honor this limit.
