Greetings
I have several rb100 and rb500 tiks deployed.
These versions cause reboots with an error message that the unit was unexpectedly restarted perhaps because of a power failure or because the Linux kernel failed.
The frequency of reboot is dependent on the traffic load on the router. One of my units rebooted about every hour.
Dropping back to 3.3 resolves the problem
My core routers are x86 boxes. I have elected to not deploy 3.6 because this problem.
I thought you might want to know.
Cheers
Joe
