My qcam process (running under gdb) was just terminated at that point. However, no reboot occurred. Looking at the dmesg logs, it seems that the Out of Memory killer terminated the task. This suggests that there is maybe a memory leak lurking somewhere in either libcamera core or the Raspberry Pi ipa/pipeline handler.<br>><br>> Nomura-san, could you send us the output of dmesg when you run into this failure again, just to check if we are seeing the same thing?<br>><br>> Thanks,<br>> Naush<br>><br>> On Thu, 8 Oct 2020 at 07:48, <<a href="mailto:tetsuya.nomura@soho-enterprise.com" target="_blank">tetsuya.nomura@soho-enterprise.com</a>> wrote:<br>> ><br>> > Dear David-san<br>> ><br>> > We took a log to catch when (how long time after application start) reboot occurs.<br>> > The logs says around 1100minuite, maybe the raspi got rebooted, no other log.<br>> ><br>> > And the older version and the combination, this phenomena never happened.<br>> ><br>> > libcamera: c3548a333f86d31213ca9f2ccc3faf743b246743<br>> > rpi-update: f794477c7c48061a720d6b9331d27f8d0300009c<br>> > (We are using the latest one for both.)<br>> ><br>> > Best Regards,<br>> ><br>> > NOMURA<br>> > -----Original Message-----<br>> > From: David Plowman <<a href="mailto:david.plowman@raspberrypi.com" target="_blank">david.plowman@raspberrypi.com</a>><br>> > Sent: Wednesday, October 7, 2020 7:37 PM<br>> > To: <a href="mailto:tetsuya.nomura@soho-enterprise.com" target="_blank">tetsuya.nomura@soho-enterprise.com</a><br>> > Cc: Laurent Pinchart <<a href="mailto:laurent.pinchart@ideasonboard.com" target="_blank">laurent.pinchart@ideasonboard.com</a>>; Kieran<br>> > Bingham <<a href="mailto:kieran.bingham@ideasonboard.com" target="_blank">kieran.bingham@ideasonboard.com</a>>;<br>> > <a href="mailto:libcamera-devel@lists.libcamera.org" target="_blank">libcamera-devel@lists.libcamera.org</a><br>> > Subject: Re: [libcamera-devel] How to activate AGC control in libcamera, or set the GAIN/EXPOSURE parameter by v4l2 command.<br>> ><br>> > Hello Nomura-san<br>> ><br>> > Thanks for your message.<br>> ><br>> > So we're not aware of any problems like the one you report but we'll see if we can reproduce it - obviously it will take a little while.
