Hi, in recent versions this was fixed by changing debug to 0 in uvcdynctrl script: http://sourceforge.net/p/libwebcam/code/ci/f1e631a4163beb926f25efa52e2c5b71128de345/
this will redirect log output to /dev/null Regards, Paulo 2015-11-06 13:54 GMT+00:00 Matti Kurkela <matti.kurk...@iki.fi>: > If /var or /var/log is a separate filesystem, the udev rule for this can > often run before that filesystem is mounted, causing the > /var/log/uvcdynctrl-udev.log file to be "hidden" under the mountpoint - > where it is also unreachable by logrotate and similar tools, and thus might > grow forever until the root filesystem is full. > > One way to remove the unreachable file would be to reboot into single user > mode - but there is an easier way: bind mount the root filesystem to some > other location.
