I shall try to interpret this message:
Trap level (TL) = 1 (userland exception handler):
Trap Type (TT) = 0x63 - implementation_dependent_exception_3 (impl. dep. #35) [1]
- corrected_ECC_error [2]
Trap Program Counter (TPC) = 0x404273f0
Trap level (TL) = 2 (exception in exception handler):
Trap Type (TT) = 0x63 - implementation_dependent_exception_3 (impl. dep. #35) [1]
- corrected_ECC_error [2]
Trap Program Counter (TPC) = 0xc0040f90
Trap level (TL) = 3 (crash):
Trap Type (TT) = 0x10 - illegal_instruction [1]
Trap Program Counter (TPC) = 0xc0040f20

This problem is very similar to another, described in message
<http://lists.freebsd.org/mailman/htdig/freebsd-sparc64/2005-March/002901.html>.
IMHO, this is hardware problem.
First, try to clean contacts (or simply reinsert) RAM and CPU modules.
