Thanks for all reply me, but I didn't resolve the problem.
The most answers pointed to hardware problem.
I run sunvts, to test only the memory and after few seconds it crashed
the machine and did the same "panic[cpu1]" message. After the reboot
ifself, I run the same test using sunvts, and it rebooted again.
Well, I thought that the problem is really the memory, but this morning
I run the Power-On Self-Test (POST) and Openboot Diagnostics (OBDiag),
and no error were displayed.
