Hi Lephio,

Is this your own machine, or is someone hosting for you?

Go into the terminal and type "python". A little python interpreter will run, and enter the following two commands:

>>> from multiprocessing import Queue
>>> Queue()

What happens after you type the second command?

Martin Konecny

Hi Lephio, did you get your problem fixed?

davide donzelli

Hi, I've read the topic about the problem that Lephio submitted.
It seems that I have the same problem:
airtime-check-system returns

CPU                            = Intel(R) Core(TM)2 Quad CPU    Q9550  @ 2.83GHz

MEDIA_MONITOR_RUNNING_SECONDS  = 6
SHOW_RECORDER_PROCESS_ID       = 15585
SHOW_RECORDER_RUNNING_SECONDS  = 7658
ICECAST_PROCESS_ID             = 14161

the log file of media-monitor:

2011-10-26 16:11:46,930 INFO - [MainThread] [MediaMonitor.py : <module>()] : LINE 38 - Setting up monitor

Finally I typed the command in the python terminal:

>>> from multiprocessing import Queue
>>> Queue()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/multiprocessing/__init__.py", line 215, in Queue
    return Queue(maxsize)
  File "/usr/lib/python2.7/multiprocessing/queues.py", line 63, in __init__
    self._rlock = Lock()
  File "/usr/lib/python2.7/multiprocessing/synchronize.py", line 147, in __init__
    SemLock.__init__(self, SEMAPHORE, 1, 1)
  File "/usr/lib/python2.7/multiprocessing/synchronize.py", line 75, in __init__
    sl = self._semlock = _multiprocessing.SemLock(kind, value, maxvalue)
OSError: [Errno 38] Function not implemented

Any help for fixing this problem?
Thank you in advance

Hi,

Are you running on a hosted server? This has something to do with permissions on /dev/shm

https://github.com/ask/celery/issues/185
http://stackoverflow.com/questions/2009278/python-multiproce ssing-permission-denied
http://stackoverflow.com/questions/6033599/oserror-38-errno- 38-with-multiprocessing

What is the output of the following 2 lines:

ls -l /dev | grep shm
ls -l /run | grep shm

davide donzelli

Hi,
yes, it is running on a hosted VPS.
the output is

root@mcp:/# ls -l /dev | grep shm
drwxr-xr-x 2 root   root     4096 Jun 13 06:46 shm
root@mcp:/# ls -l /run | grep shm
ls: cannot access /run: No such file or directory

I've tried by assigning full permissions with chmod to /dev/shm, but still not working, the media-monitor.log is the same and the uploaded files are not displayed in the Playlist Builder.

Martin Konecny

What are the permissions of /dev/shm after you've changed the permissions? Please do another

ls -l /dev | grep shm

davide donzelli

sorry I forgot to post it

drwxrwxrwx 2 root   root     4096 Jun 13 06:46 shm

this version is bugged Sad

all working fine with the .12
but no with this one ...
WE NEED A NEW VERSION BUG FREE REALLY SOON !
that's not really cool when we are online and system require update ...

davide donzelli

ok I will try the previous version.
thank you anyway.

Albert FR

to be honest, the big default of this version is the impossibility to upgrade from the previous...
and some stange dependencies not really assumed between the last version and this one...

Martin Konecny

Hi David,

This problem has nothing to do with Airtime. As you see we depend on the multiprocessing package within python, which does not work on your system (as you saw when typing into the python interpreter in the terminal).

I will try to look into this more over the weekend, in the meantime did you try the solutions that were found in those links I posted? Since we don't have a single system with this problem, it is hard to resolve.

Who is your hosting company?

Sorry for my late update about the problem. After reading carefully the links you sent me, I was able to fix it.
I added the following to my /etc/fstab/

none dev/shm tmpfs rw,nosuid,nodev,noexec 0 0

then rebooted the server. After that, everything was fine with airtime media monitor. RadiOsvaldo will give thanks you for your help!

lephio

worked! grazie davide!

Erich Kruse Nielsen

grazie davide!

Howdy, Stranger!
