CCR1036-12G-4S Kernel Failure

RouterOS General
1

Hey everyone,

I just wanted to get any advice anyone would be willing to offer.

Today my CCR1036-12G-4S with 160days uptime stopped all traffic for around 10 minutes then rebooted.

Looking through my logs this is what I found:
Jul 7 10:31:37 biz_fiber-lillian ntp,debug Wait for 0 seconds before restarting
Jul 7 10:31:37 biz_fiber-lillian ntp,debug Wait for 0 seconds before restarting
Jul 7 10:31:37 biz_fiber-lillian ntp,debug Wait for 0 seconds before restarting
Jul 7 10:31:37 biz_fiber-lillian system,error,critical System rebooted because of kernel failure
Jul 7 10:31:37 biz_fiber-lillian system,error,critical router was rebooted without proper shutdown, probably kernel failure

The NTP wait for 0 seconds lines are repeated hundreds of times in the log while the traffic is stopped then after the reboot everything is fine.

I am running 6.33.2 on this router.

Can anyone tell me if this was an NTP problem from outside the router or did the NTP client in ROS cause the kernel failure and would a ROS update fix this?

I do have an autosupout.rif file if that can help.

I don’t think NTP is the culprit. Rather those messages appeared because NTP stopped working due to another (more serious) issue. Just guessing.

Send it to support@.

Run a memory test on your router.

I have seen similar reboots on CCR1036 with faulty memory.

How does one perform a memory test on a routerboard?

5

Connect via the serial console, reboot the router and enter RouterBoot (like bios) from there you can select the option to run a memory test.

If you get any errors the problem is memory.

If your router is under warranty you can then return it to your distributor.

Also, make sure you log a ticket with Mikrotik ASAP.

all Kernel panics need to be forwarded to support@mikrotik.com. They will instruct what to do next.
