Problem Details: Since 43780b87fa7..., rpc_create() fills in a default hostname based on the ip address if the servername passed in is null. A small typo made that default incorrect. (But this information appears to be used only for debugging right now, so I don't believe the typo causes any bugs in the current kerne...
