It seems fine. The followings are the log of ps.
In every 10 minute, icmp packets are sent to 4000 IPs in our domain.
It seems the memory does not graw over 100KB.
Thanks.

Hello 9fans,
In the old article, dhog@plan9.cs.su.oz.au said:
I just noticed that the arpd on our cpu server is using 35M,
according to ps!
I don't have a lot of time right now to investigate.
Does anyone know anything about this?
Now I am also in trouble!
I started cron to ping all IPs in 16 segments of our university
to get IPs of active hosts. The interval of measurement is 10 minutes.
Then,
# at the beginning:
cpu% ps
...

bootes 16 0:00 0:00 0K Wakeme tcpack

bootes 28 0:00 0:00 36K Read icmp
bootes 29 0:00 0:00 36K Read icmp
# after a hour:

bootes 28 0:32 0:47 48K Read icmp
bootes 29 0:14 0:38 48K Read icmp
# and the system hangs up in a night with the message:
"no physical memory"
Has anyone fixed this memory leak?
