Hello, my CCR2004-1G-12S+2XS is random rebooting aprox. once a day with error in log:
Oct/24/2024 13:25:56 system,error,critical router was rebooted without proper shutdown, probably kernel failure
Oct/24/2024 13:25:57 system,error,critical kernel failure in previous boot
I think it started with update from 7.16 to 7.16.1, but not sure if it’s related. I made downgrade to 7.16 and also netinstall. Saved logs before crash and there is only standard messages.
It is interesting that router has wrong time after booting and ntp fix it after while, but it causes restart of ovpn server and another disconnect to my clients. So for users there are two disconnects, first when router reboots and second when right time is set and ovpn server restarts .
Any suggestions to software fix this problem or should I reach my supplier with hardware change or fix?
This is normal with MT devices, they don’t have RTC built in and ROS has to use some tricks to come up with approximation of correct tine (but that’s usually several minutes or even tens of minutes in the past).
I’ve no idea about how to deal with random reboots though. You may try to netinstall device and then import config (exported as ASCII text). Don’t use backup file … experience goes that sometimes configuration gets somehow garbled - even upgrade can do it if syntax of certain config changes and there’s configuration update script included in update package (and that’s not visible in configuration export), backup/restore can carry over the garbage.
The problem is that export doesn’t contain everything (it misses users with passwords, certificates, SSH keys, etc.).
What version of RouterOS is it running? There were known problems with 2004’s rebooting, particularly some of the first production runs on v6. Mine normally did pretty well, and I upgraded it to RouterOS 7 early on, but I eventually replaced it with a 2116 and deployed it somewhere else where it started to do it once every couple of weeks. I still haven’t determined the cause.
I downgraded to 7.16 but forgot to downgrade also RouterBOARD current firmware. Now i did it and router is running for 3 days without crash. I’ll wait another few days and if it will be OK we can call it solved!
Thanks, Marro.
