Hello all,
I encountered a problem with my Python script.
In this one, a job performs a task 40 times per second.
And in the loop, there is two print lines (about 20 char, going to stdout).
Everything works fine for 1 week, then the python script stops.
It means there has been about 50 million of prints before the crash !
The error from stderr is :
print "my_message"
IOError: [Errno 28] No space left on device
Then, the python process is finished and a bash script (which started it the
first time) restarts it.
So, can we expect that the buffer is flushed? No, every 40 sec, it will crash
again and again.
I tried with python -u (for unbuffered), same problem.
Of course, the disk is not empty :
$ df -h

tmpfs 221678 474 221204 1% /var/tmp
I manage to restart the python script manually and it works again, without
error.
So I guess the problem is linked to the parent process (bash script), but I
wonder ;
In which system file does the print command write ? Could we flush it ?
Thanks.
