Software versions of OpenWrt/LEDE release, packages, etc.
OpenWrt 19.07.4 r11208-ce6496d796 / LuCI openwrt-19.07 branch git-20.247.75781-0d0ab01
I installed ocserv too but I don't think its the problem
Steps to reproduce
Just let router run, maybe will stay up for a week and then at some point gui tells me can't fork, I can't login to router with ssh and I have to power cycle it.
I added swap space on a USB stick to try to keep it from locking up.
I've ssh'ed into and run the following to try to figure out what's going on.
I expected to find a process growing but nothing looks obvious to me. I just see free memory keep going down, and I see a bit of swap space used.
Any suggestions on what else I could do to figure out what's going on with the memory usage?
looking at meminfo it shows about ~100M used but the numbers don't seem to add up to that.
while sleep 60
do
date
uptime
top -b -n 1 | head -n 10
ps w | awk '$3 > 4000'
free -m
cat /proc/meminfo
printf "\n"
done
