Panic during ssh/rsync (rsnapshot)

I'm using FreeBSD 5.4RC3 (this happened on 5.3R also) as an rsnapshot server.
All this machine does, is run rsnapshot (rsync+ssh+hardlinks = snapshot disk
backups). I'm running 6 rsnapshot processes via cron every night at 11pm, so it
essentially hammers the machine during that time. About 3 out of 5 nights, my
system dies right at the beginning with either the fatal trap (see below) or the
panic (see below). It seems to die just when I get about 6 rsync processes
running.
Any ideas?
----------------
panic: sbflush_locked: cc 0 || mb 0xc3432000 || mbcnt 256
cpuid = 0
boot() called on cpu#0
----------------
Fatal trap 12: page fault while in kernel mode
cpuid = 0; apic id = 00
fault virtual address = 0x15
fault code = supervisor read, page not present
instruction pointer = 0x8:0xc077ad60
stack pointer = 0x10:0xe898ab10
frame pointer = 0x10:0xe898ab1c
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, resume, IOPL = 0
current process = 3100 (ssh)
trap number = 12
panic: page fault
cpuid = 0
