Too little swap to dumpon

[Alex Povolotsky]

Hello!

I have on one of my boxes too little swap partition to dumpon on it. Actually, it is 
too little by several bytes

 # swapinfo 
Device  1K-blocks UsedAvail Capacity  Type
/dev/da0s1b   1048448  100  1048348 0%Interleaved
/dev/da1s1b   10484480  1048448 0%Interleaved
Total 2096896  100  2096796 0%


real memory  = 1073741824 (1048576K bytes)

but I still cannot dumpon.

Moreover, I don't need any dumping besides kernel memory.

Does there exist any solution to dump on two swap partition, or to dump only limited 
amount of memory, or to dump on both swap partitions? Or I have to repartition my disk?

Limit the amount of RAM used by FreeBSD by using the MAXMEM kernel
option or the corresponding loader tunable.
