Unless they are on the same L2 segment, rogue packets or break-in
attempts would happen at different times.

It's just strange that these have been deployed for Months, but 2
locked up in the same week. And 5 days apart, with different
firmware, both in temperature controlled indoor racks. I don't think
it was triggered by some rogue WAN Packets. If that was the case, I'd
expect they both would have locked up at the same time. MRTG showed no
change in RAM usage, or CPU prior to the lockup.

I don't have very many RB4011's. One RB4011iGS+ at a tower site in an

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.

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?
