Yes, at this time I use SWAP = RAM + 1G formula. And yes, this is an
overkill especially for expensive SAS drives. I've noticed that my kernel
dumps do not exceed 2-3.5G usually.

Maybe I can collect stats for amount of Active memory used and assume that
kernel dump will not get larger than, say, Active memory + 50%?
