I have 3 CCR 1072 and in all the same thing happens to me, I'm pissed with Mikrotik, it can not be that your top-of-the-line router will pass this to you and do not say anything about it.

I've just completed removing any connection tracking from ours. We had some DDoS issues and from what I've read connection tracking can be a big problem in that case. So I've rearranged my firewall rules and adapted things to run in the raw table as much as possible and turned off connection tracking. So far things seem good, but no real test to speak of yet. We really didn't need connection tracking on this router it was just not something I really considered much until the DDoS stuff started.
I have just removed all NAT and Mangle rules, which means that CT is actually not operating on the device at all. its behind a Transparent Fortigate Firewall, so shouldnt be an issue anyway. I have moved NAT and PAT services to a CISCO 3925 router now, and havent yet seen a reboot. I wondered if the CT turned off would have actually just been the answer rather than having to install another router for this purpose of NAT / PAT. A bit annoying. Do you think if I just turned off CT it would have been ok? How have you found things have been since you did this?

Yes, when connection-tracking is disabled the device performs much better.

When I contacted Mikrotik support about device reboots they requested access to device. I provided them a test setup with one CCR1072 to act as traffic-generator and another one acting as DUT. No configuration on DUT, just routing and 4 FW rules to prevent unauthorized access.

After a few weeks of meaningless tests, the answer was - DUT is overloaded, you can't see it but it is.

With 1G?????? That is not even close to your test results published on your web site?????!!!!

- Our tests are performed with connection-tracking disabled!

That's all! You are ******!

I will say it again, CCR1009, RB1100x4 and RB4011 are working as expected in absolutely same test condition in which CCR1072 reboots it self!!!

Another restart this Saturday, is desperate, I have the router at 400km, please Mikrotik say something about it.

Email mikrotik support, they don't monitor the user forums for people having problems. Normus and a few others frequent here, but best just to email them with a support ticket and supout file.

I always send it, and the only thing they tell me is update, I already have 5 different versions. It does not help to send it, they have no idea what the restarting does.

Reading this thread as I have to upgrade a 1016 due to lack of SFP+ ports . Has worked 1y without skipping a beat barring the security updates.
Am I better off getting a EdgeRouter Infinity or building a cheap X86 box ?

Dont upgrade to CCR1072. It is not a stable product to work with.
Frequent reboots etc..

SOLVED

We get after a lot of work and trouble solving the problem of CCR1072 no longer restart or freeze.

Solved the problem was relatively easy, after more than 3 months waiting for the mikrotik team to position on the problem, solved.

We traded the CCR1072 for an MX-80 Juniper.
So....you went from a $2,000 USD router to a $35,000 USD router?
A MX80 is not a $35000 router! Where the hell do you buy your gear from ?
Where are you buying them from. Distributor list price all show $19,000+ USD. I have a friend who works for a larger ISP and they can get them for around $6,800 directly from Juniper.

Hey, guys

After upgrading CCR1072 and CRS317-1G-16+ to version 6.42.2, the kernel crashes have stopped. I hope they have really solved this great problem.

Best Regards,

Vagner Felipe Becker
Unfortunately they are not! Neither in ROS 6.42.2 nor in any other ROS version!!!

CCR1072 is not capable to handle 1Gbps bidirectional IMIX traffic and 25k sessions with conection-tracking enabled, due to watchdog timer reboots!!!

Five to ten times cheaper devices like CCR1009 and RB1100AHx4 are working fine in same test conditions!

The worst thing is that they are continuing selling this faulty device!

Contacting Mikrotik support is a lost of time!
Looks like I'm having a similar issue...

Out of curiosity - what is the device temperature? (system health print)

I have a device that runs at ~53C and reboots occasionally, and another one that runs at ~39C and works OK.

My CCR1072 works at 37-39

forget about the temperature, it is a problem in the kernel that mikrotik does not know how to solve, nor does it pay attention to us. Hopefully with the V7 this is solved, it is the only hope I have left. the top-of-the-range router does this happen, it's nonsense

We've downgraded CCR1072 to 6.44.5 and no more reboots. :D

can anyone confirm that version 6.44.5 is stable with the CCR1072?

We’ve just downgraded to latest long term, I’ll update in 48hrs.

Thanks, 6.43 discarded then... let's see if there's luck with 6.44.
I have the 6.38.3 and only had one reboot in 3 years

Yes, I can confirm it.
4 weeks without reboots, and going on.....

What reboot frequency did you have previously?

What reboot frequency did you have previously?
One to multiple times in a 24HR window.

Mikrotik support wanted me to turn off watchdog and log error / generate supout.rif once locked. The generated supout.rif files I provided after the watchdog reboot didn't yield any useful information. I opted to netinstall the latest long term release track (6.44.5). We also replaced all the SFP modules as a precaution during the maintenance window.

Mikrotik Support's Recommendation:
Before that, I suggest that you upgrade to the latest "stable" version (if there is an actual bug, then it might be already fixed). For example, v6.45.6 fixes a Watchdog reboot caused by h323 firewall helper. If your router did process voice call traffic, then the issue might be already resolved.

What's new in 6.45.6 (2019-Sep-10 09:06):
*) conntrack - improved system stability when using h323 helper (introduced in v6.45);


These are our edge routers and no NAT is being performed and we don't use h323 internally, but if some malformed h323 packet traversing these routers was causing the reboot then this may have been the cause behind the sporadic reboots. Again I'll post results of the downgrade to the Latest Long Term Release track after ample time has passed. So far ~15hrs and no reboot, this won't be conclusive until we make it past the 24-48hr mark. From what other users above have posted I'm feeling optimistic.

Here's a sequence of events on how this issue started for us:

It began with a kernel failure on one of our edge routers, I'll call it EDGE A. To fix this we decided to do a netinstall on EDGE A and bring the router up to the latest stable release at the time (6.45.5) due to CVE fixes etc. Prior to the netinstall we were running 6.42.6 on both edge routers and other than the kernel failure on EDGE A we were not experiencing reboots. We also upgraded our other edge router, EDGE B, in the same maintenance window to 6.45.5. The reboots continued after the netinstall on EDGE A only the error changed from "reboot due to kernel failure" to "reboot by watchdog timer". At this time we were under the impression there was a hardware issue with the EDGE A router so we moved the BGP peer and other connections to EDGE B and overnighted new hardware. The reboots then started happening on EDGE B. We opened a ticket with Mikrotik support, but after going through the weekend and into Monday with no response and the routers rebooting sporadically we decided to netinstall the latest longterm release track (6.44.5). Mikrotik support responded after we were done with our downgrade and reaffirmed our suspicion that there was something wrong in software and to upgrade to latest stable release (6.45.6) due to a stability improvement relating to H323 and watchdog reboots. As we did not need any of the "new" features in the Stable Release tree, and receiving this information after downgrading to Long-Term Release tree, I think we're going to stay here unless the issue persists.

Again I won't know definitively if this was the root cause until ample time has passed, so I'll update after we get passed that 48hr mark.

We are moving over 8Gbps on our 1072 at peak and have started seeing this random reboot watchdog error. We replaced with another 1072 thinking it was hardware related...once again, same random issue. Sometimes we go days without a reboot, sometimes a couple reboots in a day. It has been very disruptive.

I have disabled the h323 service as someone pointed out it may be part of the issue. It does seem to be load or random packet related. Any insight would be helpful. We are on 6.45.6.

Could be some random attack? Try to register cpu usage every second looking for high cpu usage
