title: Discord Bot running multiple times
body: <p>So I was building this discord bot that reads the latest.log file from a Minecraft server and sends user, advancement, and death messages in a specific channel. Now the problem is, after a while, the bot starts sending out multiple messages and I don't really know why. I've tried adding lines I've already sent in a file and cross-checking new lines to see if they are duplicates. This is around the time when my friend (who runs my bot on his computer) sends me a screenshot of his python.exe window which shows the 'Bot is Online' message multiple times. My best guess is multiple bot instances are running at the same time but I can't figure out how it does that in the first place. Can someone help me out?. This is my code:</p>
  <pre><code>from discord.ext import commands
  
  client = commands.Bot(command_prefix='.')
  deth_msgs = ['was shot', 'was pummeled by', 'was pricked to death',
               'walked into a cactus whilst trying to escape', 'drowned', 'experienced kinetic energy whilst trying to escape', 'blew up', 'was blown up by',
               'was killed by', 'hit the ground too hard', 'hit the ground too hard whilst trying to escape',
               'fell from a high place', 'fell off', 'was impaled', 'was squashed by', 'was skewered by', 'went up in flames', 'walked into fire whilst fighting',
               'burned to death',
               'was burnt to a crisp whilst fighting', 'went off with a bang', 'tried to swim in lava', 'was struck by lightning', 'discovered the floor was lava',
               'walked into danger zone due to', 'was killed', 'froze to death', 'was frozen to death by', 'was slain by', 'was fireballed by', 'was stung to death',
               'was shot by a skull from', 'starved to death', 'suffocated in a wall', 'was squished too much', 'was poked to death', 'was impaled by',
               'fell out of the world', &quot;didn't want to live in the same world as&quot;]
  
  players = []
  
  with open('usercache.json') as u_file:
      details = json.load(u_file)
      for dict in details:

  finally:

      f.close()
      if f_stats.st_size &gt; 1000000:
          os.remove('dupli_lines.txt')

  <p>And this is what shows up in the python window:
  <a href="https://i.stack.imgur.com/GbXGE.png" rel="nofollow noreferrer">Bot is Online x 6</a></p>
  <p>P.S.: I am aware that all my code's written in the on_ready() function, but I intended to use this bot for just this specific reason, i.e.to read in-game messages and present them in the discord channel.</p>
