Being full working network interface simply ceases to function e not responding. I have to reboot the to the same return, 10 equipment with the problem. Versão 5.7 - 2.36.
[Ticket#2011120266000099]
My observations show that this thing happens ONLY when ethernet interface sends allot of traffic(80-150Mbps). If that same ethernet ONLY receives that same traffic there is no problem.
Like this:
siteA–(RB435G_A)----wireless----(RB435G_B)–siteB
one way real world traffic (the other way is through another link with RB600A and have never developped that problem):
if siteA sends to sideB only RB435G_B have that problem 2 to 5 times per day;
if siteB sends to sideA only RB435G_A have that problem 2 to 5 times per day;
Reboot is one way to solve it , the other is to toggle the state of “switch-all-ports” to yes/no (in interface ethernet switch)
So I suppose it has something to do with some TX counters overflow and something with that switch chip in RB435G which is not present in RB600A.
Hope this gives someone a clue 
same at ticket [Ticket#2011120166000279]
what about v5.10 ? is there fixed this problem? thanks
2011120166000279 is unrelated to the issue. it talks about nv2, not about RB435G
2011120266000099 there is no such ticket
from my ticket request ([Ticket#2011120166000279]):
It’s nice to see solid nv2 on ROS5.9 working, but all over the wireless
pleasure and speeds i’m still having issues with ethernet interfaces,
which stop
possibilities of nv2 to work with it. As same as topic on
http://forum.mikrotik.com/t/radius-server-not-working-in-2-8-11/127/1i have 1g ethernet interfaces freezing(actually stopping to transmit data)
same on 5.5 5.6 5.7 5.8 5.9 of ROS, but have a solid ethernet connections
on 4.17.
ITS NOT about NV2, its about ethernet freezing
I’m having same/similar problems.
Only a reboot fixes the problem. Also noticed is that when counters are cleared on the interface even though there’s TX packets going No RX packets. The counters do not increase..
Any idea on the resolution of this Mikrotik ? Love the product this right now is beating us up. We have over 11 PTP links running 5.11 all which have experienced the loss of connectivity on the ethernet side of the remote radio.
I was the MUM-SP and talked to many people. It has the same problem as others. The MikroTik delay to talk about the problem. Support MikroTik ta ta too weak.

We’ll have to use the wireless card and network card? As in this photo?
You had any response from Mikrotik?
Because I did not.
Hi to all, i have same problem on four RB435G!!! - M I K R O T I K - W A K E - U P!!!
The problem I think is now clear!
You had any response from Mikrotik?
he didn’t contact mikrotik
Hi to all, i have same problem on four RB435G!!! - M I K R O T I K - W A K E U P!!!
please tell me your support ticket number and I will check the issue. we can’t fix something, if you don’t give us any information.
I am returning the 10 435g. And I’m buying the RB800 because they do not have the same problem. Possibly it may be a lot that came with this defect.
we are having the same ethernet freze on rb435g.
When the eth frezzes we can access the rb by wireless interface and the freezed eth is reported connected but no traffic goes through.
Enabling conncetion tracking seems to reduce the freeze issue from some hours to some days but it is not a real fix.

I can only say one fing send in supout files to mikrotik so they have a chans to fix the problem.
I openede the following ticket [Ticket#2012022166000249] including supout taken after the eth port freezed and flapped
regards
Ros
we don’t have any emails from you to support. please paste ticket number
