I'll have to disagree with Tilghman on this one. You should always have at least as much swap as ram, however double would be over kill. If for no other reason than to guaranty you get a full core dumps on system crashes. Trying to trouble shoot or root cause assess system crashes without good core dumps is difficult if not imposable.
Disk space is cheap, if you can afford the RAM having the swap equal it should be a trivial cost, and gives you more time to find fast memory leaks before systems go catatonic.
