RT-AC88U Hangs

[murat göttendelik]

Hi,

Sometimes, my AC88U router GUI does not respond to web requests (Administration)
This situation is not resolved until I restart the router manually from the switch.

During the problem, the GUI is not accessible from LAN or WAN, however, access to/from internet is not cut down.
So, all LAN clients can access WAN, and from WAN I can reach my LAN server. But I can not reach the router GUI.
Today it occured right after I accessed the GUI. before my access was cut, I saw the usage on CPU core 1 as 100%
So I assume it is some high load on CPU.
How can I troubleshoot this further ?

Edit:
This thread was deleted with no reason specified. So I created it again.
Maybe the reason is that I have a similar thread in Asus WRT-Merlin forum. But the problem is not a "Merlin" issue I guess. Because I've read in another thread that this is a known problem and that we could access router GUI , giving the command on SSH: "service restart_httpd"

This solution really works.

But after that I can access the GUI. However, the CPU is still 100% and these functions can not work:
- reboot from GUI
- change SSH access to "LAN & WAN" from "LAN Only" -> This results in losing also LAN SSH access
- use Alexa command to reboot

So, even I could access from GUI after restarting HTTPD , I was not able to use my router.

What else should I do to further analyze ?

Thanks.

Please don't repost the same question in separate threads, it makes it only more difficult for people to follow up any discussion.

Locking this.
