I don't have very many RB4011's. One RB4011iGS+ at a tower site in an outdoor NEMA box running 6.43.16 and no problems. One RB4011iGS+5HacQ2HnD running 6.45.5 at a customer site with 84 days uptime. That one used to reboot occasionally with a log message about having to reboot due to some kernel problem. It seems to have stopped that since the FW upgrade but hard to tell since it happened maybe once every 2 weeks.
I have some RB1100AHx4's which is a very similar architecture and I've seen occasional unexplained reboots on 2 of them. No lockups though. The ones that have rebooted are still on 6.40.8, a more recent one is on 6.43.16 and AFAIK has not rebooted but it did stop once responding to Winbox and had to be manually rebooted. Everything else seemed to be running fine including PPPoE server, RADIUS, and Mikrotik API. -----Original Message----- From: AF <af-boun...@af.afmug.com> On Behalf Of Nate Burke Sent: Saturday, March 7, 2020 11:24 AM To: Animal Farm <af@af.afmug.com> 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? -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list AF@af.afmug.com http://af.afmug.com/mailman/listinfo/af_af.afmug.com
