I have an embedded system (armv5tejl AT91SAM9X25 with 128 MB of RAM, running rootros based on buildroot) with Python 3 installed. I left the system working for many days and I came to do some python development work, but it seems , There was a problem creating new threads.
If I try to run the following program:
Type "help", "copyright", "credits" or "license" for more information.
>>> import threading
>>> import time
>>> def func():
... i = 0
... while True:
... i += 1
... print(i)
... time.sleep(1)
...
>>>
>>> func()
1
2
3
^CTraceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 6, in func
KeyboardInterrupt
>>> t = threading.Thread(target=func)
>>> t.start()
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python3.4/threading.py", line 850, in start
RuntimeError: can't start new thread
>>>
As you can see, when I try to start the stream, I get the above error. Some initial searches seem to indicate that the problem may be due to the system working with thread restrictions. Here is the output of ulimit -a:
