Hi!
I observe a similar behaviour on a 8.0-RELEASE-p2 i386 GENERIC
kernel.
System receives 2 BGP4 fullfeeds (approx. 310K routes each).
The system is still running, a few processes are unkillable or
die only after a long amount (1-2h) of time.
Here's the list of unkillable processes:
80871 ?? R 0:00.00 /bin/sh /etc/periodic/daily/470.status-named
76499 ?? Rs 0:00.01 sshd: [accepted] (sshd)
76922 ?? Rs 0:00.01 sshd: [accepted] (sshd)
flowcleaner looks pretty busy (for an uptime of approx. 40h):
22 ?? RL 1209:50.98 [flowcleaner]
4:17PM up 1 day, 22:22, 2 users, load averages: 7.20, 6.53, 5.81
quagga is running on the system, bgpd mgmt cli is no longer reachable:
# telnet 0 2605
Trying 0.0.0.0...
Connected to 0.
Escape character is '^]'.
^]
telnet> close
Connection closed.
#
What can I do to help to debug this ?
No console access available right now, but can probably made available.
This is a production host, but not yet super-critical, so...
