[rbak-nsp] faulty ARP process ?

[Navin Nepali]

in my case...it happened in the multibind interface...i used to remove the vlans from the multibind interface and add it again..
anyway this is not a good solution but it worked for me...:)

We do, however this problem appears on both multibind and static
    interfaces with /24, /23 and /30 mask..

I don't think it's solution here. Behaviour is like that:
- everything works fine
- some entries disappear from arp-cache
- "sniffing" on dead hosts shows, that SmartEdge does not send any ARP
requests, nor responds for requests from remote hosts (only particular
ones).
- rest of host work fine, ARPs go in both directions. - restart of arp process resolves this issue till next time (usually ~24h) Regards,

show arp-cache shows nothing related to those hosts, other hosts on the
same VLAN work fine. restarting of arp process resolves this issue temporairly (till next
problem). node: SE600 with 4x10G card
