I'd hazard a guess that there is some corruption in the flash (or even potentially a failure of the flash) - a netinstall to wipe and reset it is probably the best course of action. A bit hard to do if you don't have physical access though, so I think you might be in for a trip to Sydney unless you can get some remote hands on to it. -----Original Message----- From: Public [mailto:public-bounces@talk.mikrotik.com.au] On Behalf Of Damien Gardner Jnr Sent: Wednesday, 4 March 2015 10:18 AM To: MikroTik Australia Public List Subject: [MT-AU Public] CCR1009 crashing - how to debug? Hey All, My CCR1009 rebooted 6 times overnight. I thought maybe it was a problem with 6.25, so upgraded to 6.27. That was a bad idea, as it took a remote hands power cycle to get back into it. I then did a downgrade (which took it all the way back to 6.21.1) Seemed ok, till I tried to scp the 6.25 files up to it. As soon as I went to view flash, it rebooted again. Interestingly it hasn't upgraded to 6.25, though i don't dare try to view the files on flash to see if they actually copied.. After much swearing and praying, it seems to be stable - so long as I do not try to use winbox. Seemed like as soon as i used winbox (or the http variant), the router would reboot. However now I can't even use winbox. Seems to be stable if I don't try to login to it at all, so I think I'll leave it sit there for the day, and head to sydney tonight. What can I do to try and work out WHY it's rebooting? All my logs say are: system,error,critical System rebooted because of kernel failure system,error,critical router was rebooted without proper shutdown, probably kernel failure There's nothing else about the reboot at all. Is there any more debugging I can turn up for it? If all else fails, I can shove my old little DL360G3 back in, and fire up quagga, but if there's a way to debug and fix it without heading to Sydney, that'd be nice ;) Thanks, Damien -- Damien Gardner Jnr VK2TDG.
