Yes.
My system is highly load Sun Ultra 60 (2 X UltraSPARC-II 450MHz, 1024
MB). It have two network interfaces: hme (connected to internet) and rl
(connected to LAN). FreeBSD 5.1-RELEASE.
In period 1-2 day my system freezes without any message to console. It
freeze in work time, when people working via LAN.
With option DDB (kernel debugger) kernel may by generate strange panic:
- --------------------------------------------
panic: ipi_send: couldn't send ipi
cpuid = 1;
Debugger("panic")
Stopped at Debugger+0x1c: ta %xcc, 1
db> trace
panic() at panic+0x134
cpu_ipi_send() at cpu_ipi_send+0xb0
cpu_ipi_selected() at cpu_ipi_selected+0x38
tlb_page_demap() at tlb_page_demap+0x74
pmap_zero_page_idle() at pmap_zero_page_idle+0xe4

vm_pagezero() at vm_pagezero+0xb4
fork_exit() at fork_exit+0x90
fork_trampoline() at fork_trampoline+0x8
- --------------------------------------------
In this case, system blocked by saving core dump :(
I rebuild kernel with following options:
options WITNESS
options WITNESS_SKIPSPIN
and my system working stable (up time ~45 days, till manual reboot).
