I had a similar problem once and it ended up being that a disk was in the process of starting to fail but hadn't completely failed (and therefore didn't fail over to the mirror).
This didn't show up in any Solaris logs until *after* the server had been rebooted, the database had been restarted and then the database was shut down again. We did see some aiowait errors in the alert log though.

What is tampered process, and when it happen ? Oracle Support said if shutdown abort can't kill the process is your OS problem not Oracle. Why Oracle PMON and SMON never do anything about this ?

Rebooting to get rid of an unkillable process is not unheard of in unix land.

This is Solaris, not Windoze. I would try having the root user do the "kill -9" after doing a "truss" on the process it see what it's looking at. Doing a "ipcrm" on the shared memory segment and semaphores may also help.
