Crashes?

[TonyK132]

Is anyone else seeing this in their crash logs? This is happening to me about twice an hour. Do I need to do anything about it?

For this model that is normal to see. It has not been fixed by Asus yet it is out of @RMerlin control. You can however install Scribe and filter this out of your logs.

 

[cmkelley]

Assuming you mean RT-AC86U, how is this normal? I’ve never seen this before.

Everyone else has. That crash message is pretty much THE reason I wrote scribe.

Par for the course when my daily driver was an 86.

I've never seen this either.

SNIP

I am seeing this, seems similar?

I believe you’ll only see the dcd crash with Diversion installed.
EDIT—although, it will happen occasionally without Diversion—but not nearly as much.

Right, I tested for a while without diversion and it seems there were no more dcd crashes. I would now like to put it back; is there something I need to do to avoid crashes in this sceanrio please?
