I have a system that is being used as a high performance NFS server
FreeBSD nfs2 5.3-RELEASE-p2 FreeBSD 5.3-RELEASE-p2 #1: Tue Jan 4
19:14:40 EST 2005 root@nfs2:/usr/obj/usr/src/sys/NFS i386
Two CPUs (tried hyperthreading and not), 4 GB of memory
CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2400.10-MHz 686-class CPU)
Origin = "GenuineIntel" Id = 0xf29 Stepping = 9

Hyperthreading: 2 logical CPUs
real memory = 4160225280 (3967 MB)
avail memory = 4073271296 (3884 MB)
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs
cpu0 (BSP): APIC ID: 0
cpu1 (AP): APIC ID: 6
The NFS exported filesystem is on a Q-Logic FC card
isp0: <Qlogic ISP 2312 PCI FC-AL Adapter> port 0x4000-0x40ff mem
0xf8300000-0xf8300fff irq 28 at device 3.0 on pci3
isp0: [GIANT-LOCKED]
The disk is formated UFS2 and is big, but not *that* big yet
/dev/da1s1d 471860682 206516934 227594894 48% /usr/local/export
Every 12 hours or so the system crashes with a hard lock and no error
messages in /var/log/messages or on the screen. I've moved all the
disks to a duplicate system. If it continues to lock hard what's the
possibility the issue is SMP?
