I've configured IPVS with a port-zero UDP service - Everything looks
right, however I end up with the source/virtual/dest hash having a 60s
timeout in some cases; rather than the 30 I assigned. I tried modifying
the udp timeout using 'ipvsadm --set', but that did not seem to help.
The persistence for the port-zero 'connection' seems to live around the
60s mark whatever I configure the actual persistence to be.
Is this a bug, or just the way it works? This is on a 2.6.18 kernel,
although since it's RHEL5 the version number is totally worthless in
discovering what actual code is in there.
[root@localhost vs]# ipvsadm -Ln

Any ideas? Am I missing something obvious?
