Estou com um FreeBSD aqui num Dell Poweredge R200 que me deu uns  
kernel panics, eis as panic strings:

Code:

1)
    Dumptime: Thu Feb 26 09:02:42 2009
    Hostname: secrethostname
    Magic: FreeBSD Kernel Dump
    Version String: FreeBSD 7.0-RELEASE #0: Tue Nov  4 12:27:42 BRST 2008
      root@:/usr/src/sys/i386/compile/SECRETHOSTNAME
    Panic String: ffs_blkfree: freeing free block
2)
    Dumptime: Fri Feb 27 11:30:59 2009
    Hostname: secrethostname
    Magic: FreeBSD Kernel Dump
    Panic String: ffs_clusteralloc: map mismatch
3)
    Dumptime: Fri Feb 27 11:48:42 2009
    Hostname: secrethostname
    Magic: FreeBSD Kernel Dump
    Panic String: ffs_blkfree: freeing free block
4)
    Dumptime: Tue Mar  3 10:30:28 2009
    Hostname: secrethostname
    Magic: FreeBSD Kernel Dump
    Panic String: ffs_blkfree: freeing free block
5)
    Dumptime: Fri Mar  6 14:22:04 2009
    Hostname: secrethostname
    Magic: FreeBSD Kernel Dump
    Panic String: ufs_dirbad: /disk1: bad dir ino 1131015 at offset
1536: mangled entry

Tentei reproduzir o erro recriando a condição de arquivos grandes
sendo movidos e/ou removidos dos sistemas de arquivos e não é sempre
que acontece. No entanto 80% dos panics aconteceram durante a operação
com arquivos grandes, sendo 3 na inserção de banco de dados e 1
descompactando 2 GB (não muito grande o arquivo).

Vi recomendações para se desabilitar soft-updates nos sistemas de
arquivos mas ocorreu o panic mesmo assim, durante uma tentativa de
inserção no banco PostgreSQL.

Estou pesquisando problemas com drivers em relação a controladora
SAS e estou desconfiado pela NIC estar compartilhando IRQ com a
controladora.

Só que agora eu estou realizando mais ou menos as mesmas atividades  
(diminuí bastante o tamanho do banco, e agora ele consegue inserir:  
antes acusava arquivo corrompido ou erro de sintaxe) e nada de panic.

Daí pensei em rodar essa ferramenta do sysutils: stress. Mas  
aparentemente ela DÁ CRASH no sistema MESMO, pelo que li na  
documentação. Então não sei se vai ser útil pra testar o panic  
anterior ou se vou inventar um novo panic.


Será que meus últimos fscks resolveram o FS e era isso que tava  
causando o panic? Será que ele vai voltar pra me assombrar? Como posso  
me certificar antes de botar a máquina em produção total?

PS: uma das coisas que achei que poderia causar isso é bad RAM, pedi  
pra realizarem um memtest86+ faz 2 semanas e os caras meio que se  
recusam, não entendo pq, não entendo a dificuldade.

abraços,
