I want to use motion (https://motion-project.github.io) to stream video on a remote location with internet connection using the raspi-cam V2 on a raspberry pi zero w. Besides stream, the idea is also make timelapse or shots and upload the files to a server. I am aware that when implementing the idea on a other computer I would run into less problems, I am currently also testing on a Odroid C2.

After some days pi crashed after some days, I found this threat:https://www.raspberrypi.org/forums/viewtopic.php?t=212777. So I added over_voltage=6 . I though this would solve the problem but after 7 days, the pi went numb. I was still able to log in using ssh and use top but other things did not work, even ls . After writing down a command and pressing enter nothing happend, but you were still able to log in using another window. The motion stream was also down. I could not even restart. I let it on a couple of days to see if the system would recover, but nothing. see image.

Top after 11 days

Does someone has also experience this behaviour? I has already happy that the pi is still accessible, but I has not able to do anything. I unplugged the pi and set over_voltage=4 to see what happens, will have to wait some days again.

UPDATE:

The output of dmesg when the system freezes is as follow:

[1691678.165092] bcm2835-v4l2: vidioc_s_fmt_vid_cap: failed to setup mmal components: -62 [1691681.205048] bcm2835_mmal_vchiq: timed out waiting for sync completion [1691684.245052] bcm2835_mmal_vchiq: timed out waiting for sync completion [1691684.245101] bcm2835-v4l2: vidioc_s_fmt_vid_cap: failed to setup mmal components: -62 [1691691.925084] bcm2835_mmal_vchiq: timed out waiting for sync completion [1691694.965233] bcm2835_mmal_vchiq: timed out waiting for sync completion

    loadavg 153!!! that's crazy!!!! what's the output of dmesg – Jaromanda X May 4 at 12:01
  • It is now up 2 days, 1:34, 1 user, load average: 0.09, 0.18, 0.18. The only thing I see in red from dmesg is from brcmfmac, the last message from it is: brcmf_cfg80211_set_power_mgmt: power save enabled – David Kester May 4 at 12:40
  • well, I'd wait until it "freezes" with a loadavg of anything above 10, then do a dmesg – Jaromanda X May 4 at 12:43
