[FUG-BR] Comportamento estranho FreeBSD 8.2-STABLE

[Antonio Modesto]

Bom dia,

Ontem à noite tivemos um problema no nosso servidor proxy/roteador, ele
simplesmente parou de responder aos pings e o Nagios me enviou uma
notificação. O problema é que não foi possível verificar no monitor o
que realmente tinha acontecido, tudo que tenho são essas entradas no
console.log:

Mar  1 19:02:01 may kernel: Approaching the limit on PV entries,
consider increasing either the vm.pmap.shpgperproc or the
vm.pmap.pv_entry_max sysctl.
Mar  1 19:02:06 may kernel: acpi0: suspend request ignored (not ready
yet)
Mar  1 19:02:06 may kernel: acpi0: request to enter state S5 failed (err
6)

E essas no messages.log:

Mar  1 19:02:02 may kernel: Limiting closed port RST response from 222
to 200 packets/sec
Mar  1 19:02:04 may kernel: Limiting closed port RST response from 249

Mar  1 19:02:07 may kernel: Limiting closed port RST response from 208

Mar  1 19:02:10 may kernel: Limiting closed port RST response from 225
to 200 packets/sec
Mar  1 19:02:11 may kernel: Limiting closed port RST response from 227
to 200 packets/sec

Sábado 25/02 esse mesmo problema havia acontecido, eu incrementei o
valor de vm.pmap.shpgperproc para 500 mas pelo jeito não adiantou. Não
sei realmente se é esse primeiro erro que está ocasionando essas
tentativas de suspender o sistema.


Alguma sugestão?
