OK, can you give more detail what exactly fails, like running sotruss or
truss on the original bogofilter code that loops unterminatedly? I'd
like to see what BerkeleyDB returns as error and possibly handle it by
retrying without mmap.

What you can try and what should help is: tell BerkeleyDB not to mmap()
the file. Edit datastore_db.c, and find the location show below and
insert the line

opt_flags |= DB_NOMMAP;

before the /* open data base */ comment, as shown below near line #128;
this DB_NOMMAP is not present in the original file.  Then recompile and
reinstall bogofilter. (make ; su -c "make install-strip")

Note the line numbers are not present in the file, they are shown here
as a convenience for you to easier find things. Line number as per
bogofilter-0.10.2.
