Hoi,
It could be that it's the stats-seg that is running out. I found that with
>1M routes in FIB, we need a bit more memory. For our routers, startup.conf
has:
statseg {
size 1G
page-size default-hugepage
per-node-counters off
}
And with this:
pim@nlams0:~$ vppctl show memory stats-segment
Stats segment
base 0x7f73e5e01000, size 1023.99m, locked, name 'stat segment'
total: 1023.99M, used: 155.05M, free: 868.95M, trimmable: 831.34M
free chunks 103 free fastbin blks 0
max total allocated 1023.99M
And this machine has ~1.1M routes in the FIB:
pim@nlams0:~$ vppctl show ip fib summary | awk '{ total += $2 } END { print
total }'
925672
pim@nlams0:~$ vppctl show ip6 fib summary | awk '{ total += $2 } END {
print total }'
157334
Perhaps this helps you.
groet,
Pim
