In case switching to older version doesn't do the trick for you then you should check the RAM of your system. It can be because of a bad RAM too.

simply send supout.rif file to support@mikrotik.com

kernel failure should be documented there

downgrading will not get the problem fixed for next release, if you don't report to support

we can't fix bugs in any other way. is this really more important than your router crashing?

In versions of ROS 3 update set without worrying about problems. Now, before installing updates will think 10 times to do it or not. The situation with the stability ROS worse and worse. Really wanted to before the update is more thoroughly teste

Dear Collegues,
we had same problem on CRS and 1100AHx2 with one ospf and some eoip runnings on it, the OS where 6.19 for CRS and 6.15 for 1100AHx2.
Frustrated from continous reboots of routers we used 2 RB2011 as spare one old with OS 6.7 start to work and now is 27 hours without reboot
secon where with OS 6.19 and still rebooting all day. At he and we dowgraded also the second to 6.7 and now seem stable.

whe opened tikets for that Ticket#2014091766000231 and Ticket#2014091666000626

I hope this description helps also MikroTik developpers

I just did the upgrade from 6.11 to 6.19 and after that it rebooted twice by kernel failure. After the third reboot, it stopped. Maybe because I changed some VRRP scripts?

This RB is being used on a test enviroment (thanks god!) for VRRP. I will use It and other RB1200(that has been upgraded as well and did not had problems) to have HA on my gateway to the internet.

There is one strange thing about this router, that is it's not running On Master and On Backup scripts when VRRP interface's state changes. I have the same scripts on both routers and no problem on 1200. 1100 simply ignores the scripts.

Try with netinstall procedure.
See on my website for the correct procedure.

Just had this happen to me with 6.13 on a CCR1036...after about 90 days of uptime.
However crashes started happening every 5 minutes.
Upgraded to 6.19, been up 8 hours so far with no issues. We will see what happens when the traffic picks up today, but frankly I'm nervous.
I will be sending the supout to mirkotik.

One question, what x86 hardware do people use for RouterOS? Some have suggested it's much more stable than CCR.

Funny the time is off in the logs... i guess it is because the router is not yet up to the point he knows that he is in Pacific/Auckland +12

I have the same issue with 3 CRS210-8G-2S+IN. I send you supout.rif but have no answers yet. It appears several times per hour now. Please find a solution quickly.

Kernel failure message says - there was a problem with router. What kind of problem - you can not say just by seeing log message.

If you experience kernel failure reboot, then upgrade router to latest RouterOS version. If problem persist also after upgrade, then after kernel failure generate supout file on your router and send this file to support@mikrotik.com. No one else will be able to tell what was the problem.

Guys, change power adapter before anything else.
It happened to me many times and each time was faulty power adapter.

I received this response from Mikrotik support one or two days ago: This issue is already fixed in the latest Release Candidate version of RouterOS.

Always in such case send supout file from your router to support@mikrotik.com. We are the only ones who can try to see what went wrong with your router. It is not possible to simply guess cause of the reboot in forum. Make sure that file is generated after router has rebooted with latest current version. It would be great if in such case you could also test next version rc version.

This will definitely will be the fastest solution for your problems. Also if there indeed is software related issue, then we need to know about it in order to fix it.

Further response:
from 6.41rc13 change-log:
*) lte - improved reliability of USB LTE modems;
if possible please test this in isolated environment, because we are getting mixed reviews from customers about this fix usefulness.

Even though it says just USB LTE modems this also affects miniPCI-e:
Yes, same USB drivers are loaded for miniPCI-e and USB modems.
Please give us feedback if possible, so we can see if this fix fixes this issue.
