Hi, I’m having an issue with my slate router running out of memory. This seems to be happening on a regular basis and the only solution is to hardware power cycle the device. Can you please advise how I can troubleshoot this further to find out what’s causing the problem. I haven’t loaded any additional packages (GL-DDNS is running). there is nothing very exciting ocurring in syslog prior to the out of memory error. I recently updated the firmware to 3.1 but the problem remains.

I will factory default now and start fresh and see how that goes. thanks for responding. Definitely haven’t installed gcc compiler.
My theory is that it was something to do with DNS rebinding. I setup pi-hole on a vm last week and was using that for DNS for the network, and was getting very many dns rebinding errors in the log. I was still getting the error messages even though I turned off DNS Rebinding Attack Protection.
prior to that I had no issues.
This is my production network (home) so wasn’t doing anything ‘strange’ to the router.
It’s happened 3 times in the past week. I’m unable to login via the web or ssh when this error has occured. The unit needs a power cycle before being usable again.
I only factory defaulted and re-entered all the settings yesterday afternoon, so I will give it 24 hours before giving you the syslog. Also I haven’t re-enabled the custom DNS server setting yet, I planned to do that after 48 hours (if it stayed up, which I expect it to do so)

I’m having this same issue. Same router and keep getting out of memory which is killing processes and then I have to power cycle. I can ssh into the router and here’s the processes that have been killed:
api
lighttp
wpa_supplicant
gltertf
hostapd
usbmuxd
udhcpc
ubus
I’ve done the factory reset and it will fix the issue for a little while, over time it comes back. It’s now happening very often, multiple times a day. I just did a factory reset to try and get it working again. I have a second one of these that’s always running at home (one at home, one on the road, wireguard between) and it never has this issue.
