Agent Dies all of a sudden

I have a v880 which the agent dies after a few minutes with this message:

door_call(21, 0xFFBE1DA0)= 0

door_call(21, 0xFFBE1F88)= 0

door_call(21, 0xFFBE1F88)= 0

door_call(21, 0xFFBE1B78)= 0

door_call(21, 0xFFBE1C78)= 0

door_call(21, 0xFFBE1C00)= 0

door_call(21, 0xFFBE1D70)= 0

Incurred fault #6, FLTBOUNDS %pc = 0xFF1B3200

siginfo: SIGSEGV SEGV_MAPERR addr=0x00000000

Received signal #11, SIGSEGV [default]

siginfo: SIGSEGV SEGV_MAPERR addr=0x00000000

*** process killed ***

The agent has been working for about a month without any problems.

Any ideas? I have already re-installed several times.

Thanks,

Sonny
