Hi, we have a problem, our sun4u Sun Fire V440, started to restart spontenaously
i checked the device status but all seems ok. all i could find is the log under /var/adm/messages which contains "panic after reboot"

here is the portion of that file , do you have an idea what is causing that reboot? (the reboot after panic statement is at the end)
