It does not happen previously, just after we reboot the server than we facing this problem
PXE / kickstart installs needs to have the following services.

TFTP, NFS-HTTP-CDROM-FLOPPY, DHCP.

TFTP - This is needed to deliver the pxelinux.o binary for the boot process.
NFS or HTTP or CDROM or FLOPPY - This is needed to deliver the installation tree and kickstart file.
DHCP - This is needed for the ack request to inform the NIC card of the installation server.

If I understand you correctly you are using a netapp filer to export via NFS the installation tree and kickstart file. When you say you reboot the server, are you speaking of the DHCP or TFTP server?

This will help us to diagnose this issue.

Name
       tftpd - DARPA Trivial File Transfer Protocol (TFTP) server

Syntax
       /usr/etc/tftpd [ -r pathname ]

Description
       The  server, supports the DARPA Trivial File Transfer Protocol (TFTP).  The TFTP server is invoked when receives a packet on the port indi-
       cated in the TFTP service description.  The server is not normally started by default from

       The use of does not require an account or password on the remote system.  Because of the lack of  authentication  information,  will  allow
       only  publicly  readable  files	to  be accessed.  This extends the concept of public to include all users on all hosts that can be reached
       through the network.  This may not be appropriate on all systems however, and its implications should be considered  before  enabling  TFTP
       service.

       The server should have the user ID with the lowest possible privilege.

Options
       -r pathname    The pathname can be the choice of the user.  For example, would allow only files below to be copied using

Restrictions
       This  server  is  known	only  to  be self consistent, that is, it operates with the user TFTP program, Because of the unreliability of the
       transport protocol (UDP) and the scarcity of TFTP implementations, it is uncertain whether it really works.

       The search permissions of the directories leading to the files accessed are not checked.
