we're running CentOS 5.0 and using rsync version 2.6.9 protocol 29 on the Xen dallas host

we have a job that runs every two hours that transfers a 50+MB file to another machine. the rsync dies in the middle with a seg-fault and the following messages go into /var/log/messages. (I think it might also be causing the virtual server itself to kernel panic.)

There's more there....

Anyone experience this on the Xen hosts?
