Re: 3.1.2 issue with UnixNFSSafe.pm ?
Can you get output of
strace -f -o trace
on the affected processes? (easy way: just stop spamd, then strace the
spamd startup script.)

Did you notice that you didn't say anything about this earlier? ;-) It
seems this is the cause of your problem.

Um...I was looking at STDOUT instead of STDERR...there's lotsa
output...like 24MB within a few seconds. Not sure which of that would be
useful, but I did see alot of complaints about missing perl modules, some
under the 5.6.1 site_perl, some under 5.005.

Ok, that's going without any output as of yet. I did notice from the
console log that a perl dumped core at the same time spamd died (perl
5.6.1), but the core isn't telling me much:
This GDB was configured as "i386-unknown-freebsd".
Core was generated by `perl'.
Program terminated with signal 11, Segmentation fault.
