Verify you do not have dynamic and static networks overlapping for that
network definition. Also verify you have configured the correct MAC
address for that node in xcat and do not have overlapping MACs/IPs.
What does an lsdef for one of the problem nodes look like?

Here is the tcpdump from the management node when this happens:
14:33:20.626124 IP (tos 0x0, ttl 64, id 50528, offset 0, flags
[none], proto: UDP (17), length: 68) <new-node>.informatik-lm > <mgt
node>: [udp sum ok] 40 RRQ "pxelinux.0" octet tsize 0 blksize 1468
in the /tftpboot/pxelinux.cfg directory we have a directory that
corresponds to the hex of the ip for the new node:
[root@mgt pxelinux.cfg]# ls -lrt AC140701
lrwxrwxrwx 1 root root 9 Nov 26 09:28 AC140702 -> ttlogin01
here is the content of the file:
root@mgt pxelinux.cfg]# cat ttlogin01
#install rhels6.2-x86_64-ttlogin6
DEFAULT xCAT
LABEL xCAT
KERNEL xcat/rhels6.2/x86_64/vmlinuz
APPEND initrd=xcat/rhels6.2/x86_64/initrd.img
repo=http://172.20.0.1/install/rhels6.2/x86_64/
ks=http://172.20.0.1/install/autoinst/ttlogin01 ksdevice=eth0 cmdline
console=tty0 console=ttyS0,115200
IPAPPEND 2
For some reason, tftpboot process never proceeds to the pxelinux.cfg
directory after pxelinux.0 is served.
Stateless nodes on this cluster boot fine so I think our tftpboot
environment is OK. It's just these two nodes that have to be
installed that are problematic.
Any help is appreciated.
Thanks,
Damir.
