Unfamiliar items in the log - RT-AC87R

[DaveMishSr]

Was this fixed in the new firmware?

Unfortunately no. Either that or I have to reflash my router.

4 days 7 hours 14 minutes 19 seconds uptime.
Haven't seen the error once.

I have the error too RT-AC87U FW 376.47

I have the error too RT-AC87U FW 376.47

Confirmed, have the same thing with QoS and App Analysis on. Doesn't seem to actually cause any problems, but worrying nontheless. Same version, Merlin's build.

 

[watusi]

I have the same thing now on my AC87.

Only AFTER turning OFF both QOS and Apps Analysis.

(I don't see any way to turn bandwidth monitor off.)

Try running the following commands to resolve it (note that it won't survive a reboot or a network service restart on your router):

tc qdisc add dev vlan2 root pfifo

If using my firmware you could try inserting it inside a wan-start or a firewall-start script (not sure which is best location as I'm not sure in which scenario the traffic classifier gets reconfigured).

I don't know Merlin if changing qos to simple fifo buffer is a good solution. r2q value is configured wrong somewhere in the scripts in rom.
Better to force r2q value change with these:

tc qdisc del dev vlan2 root htb >/dev/null 2>&1
tc qdisc add dev vlan2 root htb default 2 r2q 10

And if the problem does not go away with small warning increment r2q value by 5 and check if it does go away. As per this clearos guide.
Quantum of class is small will cause packets dropouts, quantum of class is big will cause unnessesery packet slowdowns as far as I remeber.
