[SunHELP] Ultra5 keeps rebooting itself

[Gurcan Erim]

Hi,

One of Ultra5 in my network keeps rebooting itself. It
gives the error: 
/kernel/fs/procfs de_relocate failed.
procfs doing relocations.
/kernel/sys/c2audit/ undefined symbols cv_wait_sig
/kernel/sys/c2audit/ undefined symbols .....
/kernel/sys/c2audit/ undefined symbols ...
/kernel/sys/c2audit/ undefined symbols ...
/kernel/sys/c2audit/ undefined symbols ..
........

Rebooting...

and reboots.

boot -s results with same thing
and unfortunately 
boot cdrom does not work also.

Thanks in advance.
