bird becoming unresponsive after a few hours

[Darren O'Connor]

Hi all.

Last week I upgraded to Debian 8 running bird 1.4.5 - My sessions have been
up non-stop for the last 5 days, both v4 and v6. There is still a slight
delay on the first call to show route count, but not as bad a 1.4.0.

I'll continue to monitor, but for now it seems okay.

Thanks
Darren
