Occasional Reboots with Wifi Scheduler

Installing and Using OpenWrt
1

Hi,

Have OpenWrt 19.07.2 r10947-65030d81f3 running on a YouHua WR1200JS. I have the luci-app-wifischedule package installed, with cron set as:

00 07 * * Mon,Tue,Wed,Thu,Fri,Sat,Sun /usr/bin/wifi_schedule.sh start
15 00 * * Mon,Tue,Wed,Thu,Fri,Sat,Sun /usr/bin/wifi_schedule.sh forcestop

Every few days, the forcestop job causes the router to reboot. What's the best way to start diagnosing why this is happening?

Thanks very much,
Ben
