I don’t have a lot of 2011’s, but other than one that came with
one Ethernet port DOA, I don’t think I’ve seen that kind of
problem on that model. And mine are outdoors in uncontrolled
environments. Well, except for one at my office.
One just general comment, are you tracking memory utilization
(like graphing via SNMP)? I have a weirdo customer who went
from using Linux computers as routers to using Mikrotiks, I
think CRS series. He has his own /24 and gets portscanned like
crazy and has connection tracking on. He complains that his
Mikrotiks keep having to be rebooted or netinstalled and he has
all sorts of crazy explanations, but I’m convinced he is just
running out of memory due to his conntrack table filling up.
Not my problem though, so I’ve avoided getting sucked into it.
2011 has I think 128 MB RAM, the heavier duty Mikrotiks have
somewhere around 1 – 4 GB. I mean, I’ve still got a few smaller
routers in my network like 493G and 850Gx2 and I don’t see RAM
running low, but just tossing it out as a possibility.

What kind of issue? I haven't heard model-specific bugs with
those so they should "just work" forever.

I only have one RB4011 in the field, but it seems to have a
problem a couple
times a year. I now have it on a remote PDU which can
power-cycle it when it
stops responding to pings, but if they come out with a f/w
fix for this
problem, I'd be very interested!

Subject: [AFMUG] RB4011 Lockups
This week I've had 2 RB4011 Routers lockup requiring a power
cycle. They
were still passing some traffic, but stopped doing things
like handing
out DHCP, or responding to SNMP. And you couldn't log into
them via
Winbox or MACNeighbor.
One was on ROS6.44.3, the other on ROS6.45. Both of them
were doing
NAT, whereas most of my Mikrotiks are only routing. Both of
these
locations have multiple RB4011s, and only the one doing NAT
locked up.
Nothing is recorded in the log other than the reboot. These
were both
routers that have been installed for months. One router
lockup I can
attribute to a fluke, but 2 in the same week is worrysome.
Has any one
else noticed anything?
