This seems odd, since a single process on 32bit should be able to malloc()
3G.

What's your my.cnf look like?  If there isn't one, what's the text you get
back from "ps auxw | grep /usr/sbin/mysqld" ?  The defaults for the innodb
buffer pool/key buffer/sort buffer and all those things are probably smaller
than they should be for a machine that's got 8G and is a dedicated DB box.
