Been experiencing this bug for years while running NAT and connection
tracking. Rebooting every few months while running v6 latest. Does v7
have any known fixes to resolve these watchdog reboots?

Subject: Re: [AFMUG] Mikrotik 1072 Frustrations
This last year, I've seen a MikroTik CCR1072 switch from long being
rock-solid to now having occasional random reboots (from watchdog) or
100% CPU usage, which strangles the BGP process. In the latter case,
tools->profile would show the firewall taking 100% of CPU, even after
temporarily disabling all firewall filter and NAT rules and connection
tracking. Not fun.
MT tech support did not seem super helpful or interested, mostly
recommending to disable watchdog (unacceptable on a production router)
or to upgrade firmware (without specifying the suspected cause of the
problem or nature of the fix).
Tried 1 update, that didn't seem to help, have now tried another...

Some more than others. Threads in the forum all discuss the same problem
exactly. Its a connection tracking issue.. however I need connection
tracking on one particular router. I've adjusted everything I could.
Firmware and board firmware all up to date etc. Happens randomly with
low levels of traffic, high levels of traffic, sometimes a couple times
a day, sometimes weeks. No DDOS evidence at all from upstream routers.
Configs checked and rechecked by third party experts. I graph everything
about the Mikrotik and there are no clues or anything abnormal happening
before the crash. Plenty of memory, disk space, CPU etc. Replaces all
the trannies, power cables and such. Not running BGP only OSPF on the
one that is giving me the most trouble.
Even have a serial console cable plugged into them to my opengear and
set it to log pretty much everything to console including the kernel and
nothing. A hard freeze.
Then there is Mikrotik support... I've never needed their support before
until now. So I put a ticket in and the shitty attitude I'm getting from
them seems like they KNOW there is something wrong with the hardware and
they are intentionally not being helpful. It is pretty clear to see with
all the people reporting this issue that there IS an issue.
If this is any indication of how things are going to go with Mikrotik on
the newer hardware going forware I think its time to jump to an
enterprise level system. Juniper most likely. Shame because they are
just about keeping up with the demands with their hardware. Getting
closer to 100Gbps etc and ROS7 ... but at their current pace I think
we've outgrew them.
All the threads discussing this issue has been absolutely quiet when it
comes to Mikrotik jumping in to mention or try to help troubleshoot. I
think they know they had bad hardware out there and do not want to honor
warranties. I've heard rumors of bad batches of 1072's.
Anyone else encounter this?
