Exception in thread rx. Serial Monitor closes randomly

Hello !

I have been trying to monitor a running ESP32-EVB with no success. The Serial Monitor will close after a random amount of time with the following error:

--- exit ---
Exception in thread rx:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 801, in __bootstrap_inner
    self.run()
  File "/usr/lib/python2.7/threading.py", line 754, in run
    self.__target(*self.__args, **self.__kwargs)
  File "/home/george/.platformio/penv/local/lib/python2.7/site-packages/serial/tools/miniterm.py", line 445, in reader
    data = self.serial.read(self.serial.in_waiting or 1)
  File "/home/george/.platformio/penv/local/lib/python2.7/site-packages/serial/serialposix.py", line 501, in read
    'device reports readiness to read but returned no data '
SerialException: device reports readiness to read but returned no data (device disconnected or multiple access on port?)

The ESP has been working for the past 2 days perfectly fine.
The Serial Monitor also works fine until it doesn’t.

Coul you try Advanced Standalone Serial Monitor - #5 by ivankravets ?
