BAD TRAP: type=30 rp=2a10001b840 addr=2a000012040 mmu_fsr=0

Hello Gurus,

I got a system reboot due to "unix: [ID 799565 kern.notice] BAD TRAP: type=30 rp=2a10001b840 addr=2a000012040 mmu_fsr=0" on SUNW,Netra-CP2300. I guess it is caused by HW fault but not very sure, and don't know which part should be relaced incase it is HW reason really. Sincerely appreciate for your advice, or tell me I'm completely wrong.
