Strange behaviour

[Robin P. Blanchard]

I have one -CURRENT client:
CPU: Intel(R) Xeon(TM) CPU 2.40GHz (2392.25-MHz 686-class CPU)
  Origin = "GenuineIntel"  Id = 0xf27  Stepping = 7
 
Features=0xbfebfbff<FPU,VME,DE,PSE,TSC,MSR,PAE,MCE,CX8,APIC,SEP,MTRR,PGE,MCA,
CMOV,PAT,PSE36,CLFLUSH,DTS,ACPI,MMX,FXSR,
SSE,SSE2,SS,HTT,TM,PBE>
  Hyperthreading: 2 logical CPUs
real memory  = 1073610752 (1023 MB)
avail memory = 1045266432 (996 MB)
ACPI APIC Table: <DELL   PE2650  >
FreeBSD/SMP: Multiprocessor System Detected: 2 CPUs

which, when installing a new world (via nfs), consistently hangs at the end
with:

--------------------------------------------------------------
>>> Rebuilding man page indices
--------------------------------------------------------------
cd /usr/src/share/man; make makedb
makewhatis /usr/share/man


The box is useable at this point, however. I have been simply rebooting the
machine, and then running the above commands by hand after the reboot. While
'installworld' is hung (at the end, as above), this is in a 'top':

19107 root      -4    0   992K   896K getblk 1   0:01  0.00%  0.00%
makewhatis

They underlying filesystem lives on:
aac0: <Dell PERC 3/Di> mem 0xf0000000-0xf7ffffff irq 30 at device 8.1 on pci4
aac0: [MPSAFE]
aac0: i960RX 100MHz, 118MB cache memory, optional battery present
aac0: Kernel 2.7-1, Build 3170, S/N 7620d3
aac0: Supported
Options=75c<WCACHE,DATA64,HOSTTIME,WINDOW4GB,SOFTERR,NORECOND,SGMAP64>
aacd0: <RAID 1 (Mirror)> on aac0
aacd0: 34712MB (71091456 sectors)

Let me know what I can do to help further narrow down what might be going on
here. 

Thanks in advance.
