System rebooted because of kernel failure

Sveiki !

several times a day the router reboots:

jan/01/2002 05:00:01 system,error,critical System rebooted because of kernel failure
jan/01/2002 05:00:01 system,error,critical router was rebooted without proper shutdown, probab
ly kernel failure

/system resource print

what to do ?

Downgrade to 6.7 and wait 6.11

tell me please where i can download old version?

At Your Own Risk:

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

this file contains information such as ip address, vpn user logins. I can’t share this information

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

after downgrade uptime: 15h49m25s

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

I`ve the same problem with Routeros 6.13 and routerboard 411 UAHR

What can i do?

make a support output file after the kernel panic and send it to support@mikrotik.com

Ive sent You the support file but i did not receive any answers

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

Same problem here!!!

Kernel failure!!!

I’m having this same issue on a 1100AHx2

Running you scripts ore something?

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.
