Judging by the http://lists.freebsd.org/mailman/htdig/freebsd-current/2007-February/069051.html http://lists.freebsd.org/mailman/htdig/freebsd-current/2007-February/069059.html http://lists.freebsd.org/mailman/htdig/freebsd-current/2007-February/069077.html 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. -- Eygene
