      Hey Guys,

      I’m syncing 0.9.3.2

      What happens is the blockchain starts syncing normally and gets through a few weeks… and then I get tons of these:

      the entire debug log will just fill with those errors.

      if I restart Feathercoin, the blockchain starts syncing normally for a while and then it happens again

      Currently at 2 years and 29 weeks.

          Whilst I haven’t had to restart like @Aciddude, the debug.log has now hit 2.6GB with the messages.

            Blockchain sync in 3 hours. I had to restart the client multiple times, basically every time I got the error I previously posted.

            the debug log grows massively with this error.

              Do a ‘cat >> debug.log’ followed by a ‘ctrl-c’
              This will empty the logfile, even while the client is running
