Only 8800 bytes are read, resulting in an abort with a "rpc mount export: RPC: Can't decode result" error. Since it seems filers are already using a higher limit, should this limit be increased (at least for receiving, which should be safe)? -- Robbert Eggermont Intelligent Systems Support & Data Steward | TU Delft +31 15 27 83234 | Building 28, Floor 5, Room W660 Available Mon, Wed-Fri
