Yes, and you can't easily change it later. However, if you have free space on the disk you could setup another swap slice, or you could add another disk and create a swap slice on that one. If you add another disk for swap the system could then interleave the swap and might improve swap performance a little. <snip>=20 > Yes, I have been doing that, but the problem is that I don't see > swap space from that command.

I have almost brought my own system down before by executing massive or malformed SQL statements using mysql. I have also done this using the DBI perl module. And I have yet still caused major havoc on swap usage with perl alone - spurious loops and such. I would keep your eye on mysqld and the various things you are doing with perl and/or python. Also, while I'm really not sure, maybe a processes swap usage is reflected in it's regular SIZE/RES stats from top(1)?
