Hello,

i'm really new to BBB and the Can Cape but i've spent a lot of time figuring out what's wrong with my BBB.

I have a cronjob for rebooting my BBB ever night and for some reasons

the can0 interface breaks -- really randomly --- but most of the time 1- 3 hours after the reboot.

And it goes to a state UP NOARP but no more RUNNING and i have really no glue why it happened ....

Here are my log files:

Maybe something with the comunication went wrong and there could be somerhwere a memory overflow or something like that.
