Firmware Version: 1.4.7
Model: WS-26-400-AC
Board Rev: B

Has happened once before on older firmware, but I did not have remote serial access. This time I did and was able to get it to start again with #killall switch. Nothing obvious in the log. Did not have to reboot the switch... What info do you need to ID why it stopped forwarding?

Symptoms was that no traffic was passing. Looking at MAC table only showed about 20 entries, and it should have been 250 or so. Did killall switch and got the following output.
admin@SodaMain:/www# killall switch
killall: can't kill pid 832: No such process
killall: can't kill pid 833: No such process
admin@SodaMain:/www# Terminated
Logged back in and MAC table started to grow. Is passing traffic now.

Sounds like maybe a Flow Control packet lock.

AirFIBER and AC radios to my knowledge still have a flow control bug where they send endless Pause Frames until the switch buffers fill up and then the switch refuses to accept anymore packets.

Maybe explain what is plugged into each port.

Post up Your config Tabs

what this guy said ^.

also, it's important to use the latest RC on the 26-port switches - there were some bugs with 1.4.7 final, which you may be experiencing.

Just did it again... Same process to reload switch, all comes back.

Switch has:
2 Rocket M5 Titanium
4 UVC-G3 Cameras
2 Rocket M5
2 Rocket 5AC
3 Rocket Prism5AC
1 EdgeRouter Pro
1 Tycon Envronmental Monitor

4 Vlans
No LAGs
No STP

The 3 Prism's and one camera are new in the last month. Everything else been in for a year. Any workaround for the pause frame issue... and how can I tell?

Disable Flow Control on all ports first to see if this is what is going on.
If is a know issue with UBNT airFIBER and AC radios.

Well that went poorly :-(... should have thought about it more... but..

Dutifully went through and set flow control to NONE on all ports... even the uplink on the SFP port... (bad idea).. Caused the link to go down.. and NOT come back. 60 seconds went by... nothing. Serial into switch, link down. reset config to BOTH on port, nothing, killall switch, nothing.. reload cold.. nothing.. dropping to the CLI and doing a reboot... got it back..

However. I have managed to disable flow control on all AC sectors, so we'll see. Last time was 5 days between drops.

Please post up screen grabs of all you Config TABs

Do you have port's SPeed/Duplex set to Auto? <== SOUNDS LIKE NO

Turning OFF FC should not cause this.

Duplex is Auto.. Images attached. Everything else is pretty much defaults.
