Judging by the
people are varying in their opinions ;))  So your mileage may vary.
Seems like the old 2:1 rule is not very cost-effective for common
setups, but, again, it depends on the situation.

To your point about minidumps going out-of-bounds (I know nothing
about this problem: was not bitten by it):
a) if you don't need kernel dumps, disable them completely with
   'dumpdev=NO' in /etc/rc.conf;
b) if you do need kernel dumps _and_ the problem with minidumps
   persists, you can either fix the issue or provide enough swap
   and use full or mini dumps.

I have not heard about any problems with large swap sizes, so can not
comment on that.

My couple of cents.
