CCR1009-7G-1C-1S+ v7.6
Seeing this in the logs
router was rebooted without proper shutdown, probably kernel failure
then
kernel failure in previous boot
Any suggestions? Where should I look to get more information?
You might want to netinstall the device to make sure there isn’t an issue with the flash or the os install. I would also check the capacitors to make sure none are failing. If you have a backup power supply, I would also test that as well.
That mirrors my thoughts.. 
Cheers
I got the exact same problem with my CCR1009-8G-1S-1S+
I will try Netinstall.
edit: Won’t do Netinstall… as it factory reset the routeur, I do not want that. Maybe 7.7 Beta? Altrought I don’t see anything “fixing” in the release.
Update me if it fix it.
Wasn’t a power supply issue.
Very interesting that you have the same issue… When did yours start?
I sent the supout to support, trying NetInstall now..
Been a couple hours and it hasn’t rebooted..
First tried restoring a rsc export after the NetInstall, that didn’t go well, didn’t want to restore the full backup because I didn’t want to restore the corruption.. But I did because the rsc import was not good..
Been a couple hours and still good.
Edit: Not anymore.. Rebooting again..
I think it started at the beginning of the week. I’m not sure when I updated to 7.6, but I feel like it’s related.
Tried 7.7Beta8 and it’s still rebooting.
Wish I could go back to 7.5 and try, but the “Downgrade” options just reboot into 7.6 
ok, fond how to downgrade, pretty simple in fact.
Get older version here : https://mikrotik.com/download/archive (you need “tile” .npk for the CCR1009)
Upload into “Files”, then go into “Package” and click “Downgrade”. Router will reboot and be into the older version.
Trying 7.5 for now.
edit #1 : 7.5 crashing, trying 7.4.1 (can’t recall what version I had before 7.6).
I’ve got the exact same issue on a CCR1009-8G-1S-1S+ that has just started in the last couple of days. I was on 7.3 when it started, upgraded to 7.6 and it has crashed one more time a couple of hours later. Seems a bit of a coincidence that that three of us have the same issue starting around the same time with similar models??
Yes, I did the same, 7.5 still crashed for me too.
I had a transparent firewall set on two ports, removed them because the CCR1009 was unstable, the reboots stopped..
Tomorrow will check for blown caps but unplugging the two ports stopped the crashing.
Hoping support responds and doesn’t just fix the issue with an update without telling me like last time..
7.4.1 seems to be stable for me, I’ll update here if it still crash.
edit: crashing.
i think is too early for netinstall.
what tool/profile showing?(keep it running)
on logical reason would be, that one of those parameters getting overloaded
Netinstall has already been done.
Indeed..
didn’t know about the tool/profile
It’s currently running (I downgraded to 7.4.1), total is around 2 to 3.5, with “profiling” at around 2.5 and management 1.0, the rest is under 1.0 (most at 0.0).
Mine has been running fine for almost 24 hours now on 7.4.1. Might need to look at the changelog to see what is new on 7.5 that could cause that Kernel Panic.
I’ve also enabled syslog, hoping to see something in the log before it crash (if it does).
Just FYI my CCR1009 was running 7.5 for over a month without issues. I replaced it with a CCR2004, so the 1009 is not currently in use.
The only issues I had with 7.x and the CCR1009 were/are:
- sd card no longer works
- in earlier 7.x version there was a bug with l2tp/ipsec where it would go into high utilization randomly. It has not happened since 7.3.x from what I remember.
7.4.1 just rebooted on me.
Less than 7.5 and 7.6 but still happening.
I have a CCR1016-12S-1S+ doing the exact same thing. It had been fine for over a month on 7.6 but in the last week since 11/24/2022 it has rebooted around 10 times. Some of the times are shortly after a previous reboot. It can’t be a power supply issue as it’s a dual PS router and it’s fed by a UPS which also feeds other devices without issue. Any way of getting Mikrotik to look at the supout files to figure out why?
Open a support ticket and include the supout files..?
I just got a response that it might be related to connection tracking.
