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.
