Hm, the "invalid message format" is unsurprising if the network suffered a glitch and delivered bad data, but the backend crash is not good. And what do you make of the apparent junk on the log line? (What's your log_line_prefix exactly?) Given that this sounds like it won't be easy to reproduce, I'm hoping you have a core file left from that and can get a stack trace from it. That would give us some clue where to look. regards, tom lane
