Hello

I have a ros node which successfully executes the following lines of (pseudo)code:

sc.playWaveFromPkg("sound_play", "/home/jan/synthts_et-master/synthts_et/out_tnu.wav");
sleep(seconds + 1);
sc.stopAll();

I get the desired sound for approximately 300 iterations or so (which corresponds to hours of audio). However, after that my soundplay_node.py crashes with the following error message:

[ERROR] [1524690159.260685]: Exception in callback: Environment configuration is invalid: cannot locate rospack ([Errno 24] Too many open files)
[INFO] [1524690159.261880]: Traceback (most recent call last):
  File "/opt/ros/kinetic/lib/sound_play/soundplay_node.py", line 273, in callback
    sound = self.select_sound(data)
  File "/opt/ros/kinetic/lib/sound_play/soundplay_node.py", line 208, in select_sound
    absfilename = os.path.join(roslib.packages.get_pkg_dir(data.arg2), data.arg)
  File "/opt/ros/kinetic/lib/python2.7/dist-packages/roslib/packages.py", line 188, in get_pkg_dir
    raise InvalidROSPkgException("Environment configuration is invalid: cannot locate rospack (%s)"%e)
InvalidROSPkgException: Environment configuration is invalid: cannot locate rospack ([Errno 24] Too many open files)

The only nodes running are the soundplay_node.py and the node publishing the .wav file. I have contemplated on this issue and my own thoughts have halted to a standstill. Maybe you have some insight into this. Thank you!

This is most likely a file handle leak in either soundplay_node.py or some of the code it uses.

I'd recommend you post this over at ros-drivers/audio_common/issues.

Btw: may I suggest a topic title change? The current title suggests that already after a (short) while the node crashes, while in reality:

I get the desired sound for approximately 300 iterations or so (which corresponds to hours of audio).

Hello! Thank you for the responses. I followed your suggestion and edited the topic title. I will also post this at ros-drivers/audio_common/issues.
