What platform are you using? Mine is CentOS 5 on x86_64. It runs as a
Xen DomU but from what I read on the linux-ha users mailing list this
shouldn't be the issue. The production system will run on the bare
metal (not under Xen).

My experience with LVS at a previous workplace (a very large ISP) was
also excellent - they had a couple of LVS servers in front of hundreds
of mini-clusters (each such cluster service its own web or other
network application, sometimes sharing disks using DRBD).

The difference, I suspect, is that I'm trying this now with version
2.1.2 on CentOS 5 and x86_64, as opposed to possibly older version of
everything (RedHat version, LVS, hardware (i386)).

Thanks for your input,
