before last update (2 days ago) I have problem:
when many packets run over interface - network inaccessible - no ping,
nothing not works. frequently I see problem when update source three
with fast cvsup mirror. But - no problem with slow mirror.
if I down/up interface - all OK short time - 20-30 seconds.
After last update, problem still, but, system hang after
ifconfig bge0 down && ifconfig bge0 up &
I cannot correct shutdown - only reset.
when system hang, 1 process get all cpu resources:
ps -auxww | grep rout
root 1545 100,0 0,0 2704 912 ?? R 0:21 0:00,73 route add default
192.168.250.254
ps -auxww | grep ifconf
root 1569 0,0 0,1 7912 1392 v1 L 0:22 0:00,00
ifconfig bge0 down
root 1572 0,0 0,1 7912 1392 v1 L 0:23 0:00,00
ifconfig bge0 down
root 1575 0,0 0,1 7912 1392 v1 L 0:23 0:00,00
ifconfig bge0 down
root 1578 0,0 0,1 7912 1392 v1 L 0:23 0:00,00
ifconfig bge0 down
network unrecheable
if, before first
ifconfig bge0 down && ifconfig bge0 up &
I connect to network with ssh|another tcp services - system hang later
5-10 seconds after down/up interface
