### What is the problem?
Octoprint and octodash are no longer accessible after about 10 minutes of printing whilst the print is continuing and successfully complete!
It seems to come from the serial communication as my setup is auto/115200 but before crashing communication is displayed as auto/auto
I managed for weeks before installing octodash or octoscreen to print with octopi with no issue
From what I understand: Octodash or Octoscreen are sending API request to Octoprint and the Nb of thread is continuously growing up to reaching 31 (which seems to be the limit for my system).
I don't see any error in the log
What did you already try to solve it?
The same issue occured with Octoscreen and I replaced Octoscreen with octodash with exactly the same problem
Have you tried running in safe mode?
Yes
Did running in safe mode solve the problem?
No

octoprint server message
The OctoPrint server is currently not running
If you just started up your Raspberry Pi, please wait a couple of seconds, then try to refresh this page.
If the issue persists, please log into your Raspberry Pi via SSH and check the following:
- Verify that the process is running:
ps -ef | grep -i octoprint | grep -i pythonshould show a python process:
pi@octopi:~ $ ps -ef | grep -i octoprint | grep -i python
pi 1441 1 6 11:12 ? 00:00:15 /home/pi/oprint/bin/python
/home/pi/oprint/bin/octoprint --host=127.0.0.1 --port=5000
- If it isn't, the question is why. Take a look into
~/.octoprint/logs/octoprint.log, there might be an error logged in there that helps to determine what's wrong. - You might also want to try if you can restart the server (if no obvious error is visible):
sudo service octoprint restart.
If all that doesn't help to trouble shoot the issue, you can seek support on the OctoPrint Community Forum. Please provide your OctoPi and OctoPrint versions as well as your octoprint.log and explain what you already tried and observed as detailed as possible.
