RT-AX89X going out of memory every 10 minutes (asd process?)

Level 8

Hello, my router froze up overnight, so I rebooted it, and ever since the logs are showing that it is going OOM about every 10 minutes. First it starts spamming:

May 17 10:44:26 kernel: [ 5872.720019] wlan: [0:E:QDF] NBUF alloc failed 12107B @ dp_get_ppdu_desc:3430

Then it looks like a high memory killer kicks in and kills a process called asd:

 Looking back at when the router locked up initially overnight, it seems like it tried to look for a firmware update automatically around 4am, (which is strange because I have auto updates turned off), then started spamming the 'NBUF alloc failed' message:

 Any help greatly appreciated!

I just went with the beta version, hope it works. I had the tech out at my house all day, only to discover it wasn't my ISP...

Being a little nervous about a beta version (Asus has a history of voiding its warranties with beta firmware), I tried rolling back to the previous official release (47191).  The underlying issue still persists.  I can see at least one core hitting 100% nearly all the time, and memory usage slowly climbs to 99%, then the process gets killed automatically and it's starts it's run all over again from ~50%.  Been doing this for about an hour now, while I try to get through to support.  (phone line busy, web chat seems to sporadically disconnect).  Not giving me a lot of confidence in the brand.

I totally agree, cant have these issues, putting people down for hours. If they dont fix this soon, I will be looking at other brands

Seriously, the whole day trying to figure out if ISP was an issue believing router is fine. But came on here to find out it’s the ducking ASUS router issue. Might have to abandon this brand and ask others to avoid if they don’t fix it. How would a non-tech person know all this ******?

This is not specific to RT-AX89X, it happens also on RT-A56U !!
I have the same kind of problem since this morning (May 17) with my RT-AX56U. After a few mins, internet traffic get slower and slower until it blocks totally. CPU is very high and memry is about 90% of total RAM. The only solution is to unplug/replug the router
ssh-ing to the router and then issuing "kill -SIGSTOP $(ps | grep '[a]sd$' | awk '{print $1}')" make the router back to normal: CPU ~10% and RAM ~60%
I don't know if there is a new firmware (beta or not) for the RT-ZX56U to fix the problem
Firmware is 3.0.0.4.386_49380-gb9aceaf (the latest one)

The beta firmware in this thread is working for me, been stable for a while now. Hopefully they come out with an official version soon.

Has anyone verified the source of that 'Beta' the links all point too?  I see different 'Beta' versions, from different places, some even from 'Tiny URL', I mean WTF?   I smell a scam out there.  No hashes, some not cert.  ASUSTEK>  Where The F@#@ are you here?  Fox this crap!

I flashed this firmware (https://tinyurl.com/2p83cmem), then flashed back to the last version of the ax89x firmware and it was fine

GTFU with the tiny-url's that point to someones personal storage hosted by ASUS - but are actually some anonymous persons storage at Asus.  That is exactly the issue with this crap.  Where did this originate?  It isn't even close in size to any recent firmware files.  I may be wrong but the incredible bad red-flags are there.  I want a fix issued by Asus or I leave the GD brand.  This is not the fist catastrophic failure from the brand.

This is BS.  I have a new router being delivered tomorrow morning via FedEx (different brand) and it cost me a boatload to get it promised for delivery in the AM.  And I will still have to configure the d#$m thing,

ASUS - WAKE the F Up!  Fix and answer this problem.
