i am in the process of debugging a audio-installation that is running on a RPi B+.
i noticed that the RPi restarted because it was running out of memory.
it seams that the pd-gui.tcl process i piling up memory and eventually crashes.
any hints on what could be the root of the problem?
USER PID %CPU %MEM VSZ RSS TTY STAT START TIME COMMAND
root 636 2.0 49.9 543008 474092 ? Sl Dec02 33:11 wish /usr/lib/puredata/tcl//pd-gui.tcl 5400
root 626 6.5 0.4 30272 3888 ? Sl Dec02 108:16 puredata /home/pi/MAW_ArbeitIstUnsichtbar/03_LightRoom_Loop.pd
currently (according to the ps aux —sort -rss|head) it seams that the memory usage is decreasing again.
but right after a restart, it looks more like this:
root 759 9.2 1.4 27096 13900 ? Sl 10:44 0:03 wish /usr/lib/puredata/tcl//pd-gui.tcl 5400
root 734 6.5 1.2 30256 12016 ? Sl 10:44 0:02 puredata /home/pi/MAW_ArbeitIstUnsichtbar/02_DarkRoom.pd
i am running vanilla pd, use wiringPi_gpio to read out Sensor data and use netreceive/netsend to communicate with a remote control which sends OSC via UDP…
i also setup the RPi so that whenever PD is unresponsive for some time, it restarts the raspi…
the raspi also runs LXDE - is it much better to run pd without gui??
