I just encountered the same problem on a FreeBSD 8.2-RELEASE-p3 server today.  Swap was at 100% and processes were being killed.  I used ps ax and killed all the processes with W status that I could.  Swap usage went down to 99%.  This was a production server so was forced to reboot.  After the reboot, the system came back up with the same process set and zero swap used.  Shortly after that a core image appeared and the root filesystem was full.  The core file was about 1 GB.  However, none of my processes are anywhere near that.  The specific process that was dumped is only about 140 lines of C code and doesn’t have any dynamic storage used, just a couple of short character strings and one integer.  The binary file is 23KB.  I couldn’t take time to run gdb on it as it was affecting production.
