Error: brctl: SIOCGIFBR

For Developers
1

We develop a router with openwrt and it is working but suddenly the following message appears

daemon.err uhttpd [811]: brctl: SIOCGIFBR: No error information

and the log seems infinite ...

I think that the memory is saturated and the equipment crashes and I have to turn it off and on but since the equipment is remote that is complicated

I am using socket.http and https.request to write to a url

any idea what might be happening

thanks

Post the output to pastebin.com redacting the private parts:

ubus call system board; uci show uhttpd; uci show network; \
netstat -l -n -p | grep -e uhttpd; pgrep -f -a uhttpd; \
ip address show; brctl show
