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

shievan

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:

Filtered out some spam in the logs and duplicate prints for alloc fail and it's obvious some timer is causing this every 10 minutes.

Same exact issue here! Started last night... 
I'm within the return window debating if I should return. Anyone contact ASUS?

I opened a support chat and they suggested I downgrade the firmware. Trying that now.

I've tried downgrading to the previous firmware, it didn't seem to change anything 😞

Downgraded firmware to previous version and the router has not locked up in the last 40 mins. This might be a server side issue on ASUS for the firmware check.

Did you do a manual upload of the prior firmware version? 

Looks like the last firmware update was on 5/12 (5 days ago). 
Current Version : 3.0.0.4.386_47468-g73fe1fe

PNWBob_0-1684351469472.png

 

Yeah, I grabbed the 3.0.0.4.386.47191 version from the support page. Then I manually uploaded it.

It's not saying the firmware was updated 5 days ago, that's the anti-virus/site blocking signature file update. Your firmware version is from Oct 2022.

Same happening here. Started this morning. Seems my router was auto updated even though I have automatic updates disabled.

Are your cases the same?
