Thanks James,

Looks like I found the issue.

this machine is also running alice-lg and birdwatcher.

they consuming a lot of memory when bird-lg and alice-lg+birdwatcher all running.

so i test to disable them

birdc show route table master count
BIRD 1.6.3 ready.
822957 of 822957 routes for 819943 networks

free -h
total used free shared buff/cache available
Mem: 31G 478M 30G 1.1M 772M 30G

regards,

I've had similar results on Bird v1.
