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.

I haven't heard model-specific bugs with those so they should "just work" forever.

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! -----Original Message----- From: AF [mailto:af-boun...@af.afmug.com] On Behalf Of Nate Burke Sent: Saturday, March 07, 2020 11:24 AM To: Animal Farm 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.
