Bug#678519: general: after about 1 month of uptime, routing of IPv6 packets is no longer possible, and IPv4 routing becomes slow and unpredictable. Rebooting brings all functionality back, and back to speed. so far the best way for me to discover is to try a ping6, and reboot the firewall (this machine), when ping6 from the inner network fails.

retitle 678519 after about a month, routing gets wedged
# not a general problem affecting a large portion of the archive
reassign 678519 base

Thanks for starting to track this down.  Any idea which package might
be responsible?

Rudy, is this a regression, or has this system always behaved this
way?  How many times has it happened?  How reliable is the 1 month
gestation time?  When did it start?
