I have noticed this problem too, but in my case mfs is the culprit. My
/tmp is a mfs: I can fill the swap in creating a large file on /tmp and
then deleting it. There is something strange though: I swap on wd0 and
sd0 and /tmp uses sd0. If i creat/delete a large file on /tmp, this
also fills wd0:
$ swapinfo -k
Device 1K-blocks Used Avail Capacity Type
/dev/wd0b 20480 20068 348 98% Interleaved
/dev/sd0b 58968 19712 39192 33% Interleaved
Total 79320 39780 39540 50%
(after a 19Mb file creation/deletion)
