rac 10.2.0.3 on solaris 10 - machine restart without log

all,

do you have such experience about machine restart by itself without indication why ???
there is no indication on OS log - no log entries about why machine restart there is no indication on CRS log - no node eviction information

simply machine restart by itself :)

on each machine, I have 1 ASM instance and 2 database instance since 4 months ago, the machine was fine, without problem and never restart by itself of course :)

please let me know if someone has the same experience...and please give me a clue ......
