Hi Graeme,

64bit SUSE Linux 10.0, kernel 2.6.13 - ipvsadm 1.24-110.  Hmm, this
reminds me that director#2 doesn't seem to have this problem, but that 
system is somewhat newer too - openSUSE 10.2, kernel 2.6.24, ipvsadm 
1.24-150.

This is from a point when all inactconn were positive:

# ipvsadm -Ln --stats
