MPI not running on Scyld

I installed Scyld Beowulf 27z-8.
When I boot a slave node, here are the lines that seems errors. I also
provide the complete log file.
eth0: 3Com 3C905C Tornado *** INVALID CHECKSUM 002F ***
hda: no response (satus = 0xa1), resetting drive
hda: no response (satus = 0xa1)
hdb: no response (satus = 0xa1), resetting drive
hdb: no response (satus = 0xa1)
It obviously looks for hard drives though we've diskless nodes ...
Here is what the /etc/beowulf/fstab looks like:
/dev/ram3 / ext2 fs_size=65536 0 0
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
$MASTER:/home /home nfs defaults 0 0
Even displaying these errors, the nodes complete booting sequences and
become UP. But if I try to run an MPI program (one of the examples)
It says, on master node:
p0_7699: p4_error: net_create_slave: bproc_rfork: -1
p4_error: latest msg from perror: Operation not permitted
bm_list_7650: p4_error: interrupt SIGINT: 2
and on the slave nodes:
vmadump: mmap failed: /usr/lib/mlibbproc.so.1.0.0
Can anyone tell me what is wrong.
