GateD has nothing to do with this, fyi.
The kernel has a limit on the amount of kernel VM that can be allocated to
tables such as these. You may do a "vmstat -m" to see. Look at:
Memory statistics by type Type Kern
Type InUse MemUse HighUse Limit Requests Limit Limit Size(s)
routetbl161703 22113K 22127K 40960K 240489 0 0 16,32,64,128,256
Memory Totals: In Use Free Requests
23618K 23K 255740
You will probably find your "Limit" field to be 20K.
It's not real obvious, but this limit is derived from hald of VM_KMEM_SIZE.
I compiled a kernel with
options "VM_KMEM_SIZE=83886080"
and fixed it. Alternatively, one could specify this in boot/loader.rc, as
I think someone stuck in a way to alter it in that manner.

# netstat -rn|wc

Some internal routes probably present, but > 75K routes.

What speed connection do you have, anyways? I wait maybe 20 seconds. :-)

If this fixes the issue for you, please take the time to help them as I've
taken the time to help you. Much appreciated.
