Anaconda mode stops working for autocomplete after a while

[synic]

Description :octocat:

anaconda-mode server stops responding, so python autocomplete stops working, anaconda buffer stops receiving output. Killing the anaconda process and toggling autocomplete makes it work again.

I don't see any particular errors in the buffer that would indicate a crash, though there is a lot of this:

<ipython-input-1-23f9ccda9a46>:98: DeprecationWarning: Providing the line is now done in the functions themselves like `Script(...).complete(line, column)`
  result = f(jedi.Script(source, line, column, path, environment=virtual_environment))
<ipython-input-1-23f9ccda9a46>:98: DeprecationWarning: Providing the column is now done in the functions themselves like `Script(...).complete(line, column)`
  result = f(jedi.Script(source, line, column, path, environment=virtual_environment))
<ipython-input-1-23f9ccda9a46>:154: DeprecationWarning: Deprecated since version 0.16.0. Use Script(...).get_signatures instead.
  signatures = script.call_signatures()
<ipython-input-1-23f9ccda9a46>:130: DeprecationWarning: Deprecated since version 0.16.0. Use Script(...).complete instead.
  for definition in script.completions()]

Reproduction guide :beetle:

• Start Emacs
• Code in python for a while
• Autocomplete eventually stops working, and no more output is appended to the *anaconda-mode* buffer

When this happens and you manually kill the log buffer does emacs regenerate? If it does your log buffer is overflowing. The root of the issue may then be a conflict between latest version of jedi and ipython or anaconda-mode. The warning above just says that the way jedi is invoced is deprecated.

I have similar issues with LSP and python in my work environment however I have always though this would be an issue of my work box (its pretty slow), so this could still be an issue with us. Not sure if we can limit the size of a buffer in emacs 🤔.
