Time wait bucket overflow

[roldogg]

I have an Asus RT-AC3200 as my main router, 2 switches, and a Netgear EX7000 setup as an AP on one of my switches. This morning I noticed my internet connection being really slow, and when I checked my syslog, all I see if this:

Any idea what's causing this or how to fix it?

Which firmware version? Only time I've seen this was with hggomes fork firmware 380.x

This happened to me once, then I did a factory reset and it fixed the problem. Not sure if this is useful to your situation:

What does it show?
nvram get ct_tcp_timeout

My router (RT-AC68U Asuswrt-Merlin 380.57) shows this values:
0 432000 120 60 120 120 10 60 30 0

432000 is a bit high

My range:
0 2400 120 60 120 120 10 60 30 0

I'm running Marlins 380.57. I reset the modem last night, and today I'm not getting that anymore.

I started getting this problem also it's only when I started using wireless 2.4 Ghz. I never had a problem before I guess I will have to reset it again.
