I have some raspberry pi running some python code. Once and a while my devices will fail to check in. The rest of the python code continues to run perfectly but the code here quits. I am not sure why? If the devices can't check in they should reboot but they don't. Other threads in the python file continue to run correctly.

class reportStatus(Thread):def run(self):checkInCount = 0while 1:try:if checkInCount < 50:payload = {'d':device,'k':cKey}resp = requests.post(url+'c', json=payload)if resp.status_code == 200:checkInCount = 0time.sleep(1800) #1800else:checkInCount += 1time.sleep(300) # 2.5 minelse:os.system("sudo reboot")except:try:checkInCount += 1time.sleep(300)except:pass

The devices can run for days and weeks and will check in perfectly every 30 minutes, then out of the blue they will stop. My linux computers are in read-only and the computer continue to work and run correctly. My issue is in this thread. I think they might fail to get a response and this line could be the issue

resp = requests.post(url+'c', json=payload)

I am not sure how to solve this, any help or suggestions would be greatly appreciated.

Thank you

A bare except:pass is a very bad idea.

A much better approach would be to, at the very minimum, log any exceptions:

import tracebackwhile True:try:time.sleep(60)except:with open("exceptions.log", "a") as log:log.write("%s: Exception occurred:\n" % datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'))traceback.print_exc(file=log)

Then, when you get an exception, you get a log:

2016-12-20 13:28:55: Exception occurred:
Traceback (most recent call last):File "./sleepy.py", line 8, in <module>time.sleep(60)
KeyboardInterrupt

It is also possible that your code is hanging on sudo reboot or requests.post. You could add additional logging to troubleshoot which issue you have, although given you've seen it do reboots, I suspect it's requests.post, in which case you need to add a timeout (from the linked answer):

import requests
import eventlet
eventlet.monkey_patch()#...
resp = None
with eventlet.Timeout(10):resp = requests.post(url+'c', json=payload)
if resp:# your code
