48 == ASCII '0', so I'm betting that this represents the backend
thinking that a new message starts in the middle of some text.
In other words, most likely the client sent a malformed message.
You need to figure out exactly which client is causing it ---
enabling log_connections and adding ID info to log_line_prefix
may help.
