Subject: ARP cache problems / slow connect times in routed mode - Bug #596 opened
Date: Fri, 31 Mar 2006 15:49:42 -0500 [thread overview]
Message-ID: <442D95E6.3030602@tektonic.net> (raw)
Synopsis:
A user of mine has debugged this issue for me. It seems a Xen guest in
routed mode wants to arp cache any host it connects to with the MAC
address FE:FF:FF:FF:FF:FF. The user also identified long connection
times due to this. While a remote host is in the arp cache connection
times are fast (30ms or so), when it is not it can be well over 1000ms.
They have provided me the tcpdump output that proves this. They also
proved it is due to the ARP cache by statically adding a remote host to
the ARP cache and noting that connection times are very low.
Full debugging information is attached to the bug.
