Could be down to this in system.sh (>> appending to the cron on each reboot).
if [ "$FREE_SPACE" != "0" ]; then
echo "0 * * * * /tmp/sd/yi-hack-v5/script/clean_records.sh $FREE_SPACE" >> /var/spool/cron/crontabs/root
fi

I will have a limited time before 17 June to check this issue but you can comment it in the system.sh so it will not kick off and will remain disabled.
#if [ "$FREE_SPACE" != "0" ]; then
# echo "0 * * * * /tmp/sd/yi-hack-v5/script/clean_records.sh $FREE_SPACE" >> /var/spool/cron/crontabs/root
#fi
It might be also useful to remove those jobs from the cat ../../var/spool/cron/crontabs/root
Seems reliable after removing these jobs from the cron, but the outdoor camera is still having issues.

#63 should be helpful with swapfile

Edited init.sh with the following and rebooted but the video still drops, the camera also now doesn't respond to pings but can see it is still connected to my router.
sysctl -w vm.dirty_background_ratio=2
sysctl -w vm.dirty_ratio=5
sysctl -w vm.dirty_writeback_centisecs=100
sysctl -w vm.dirty_expire_centisecs=500
sysctl -w vm.vfs_cache_pressure=200
sysctl -w vm.swappiness=40
echo 5 > /proc/sys/vm/laptop_mode
echo 60 > /proc/sys/vm/swappiness
/home/yi-hack-v5 # cat /proc/sys/vm/swappiness
60

This value means that it will start moving to the swapfile when the memory is 40% full. You might amend it to 20 to ensure you have the best performance. 60 works fine for yi_dome but that camera is limited with memory by design.

It still crashes with a value of 20 unfortunately.
