The error message suggests that you're running out of swapspace.  Do 
you have excessive numbers of sendmail processes running, perhaps due 
to someone mail-bombing your server?

There have been security holes fixed in sendmail since 8.12.8, and 
8.12.11 is the most current version.  Some of the fixes have been 
backported to FreeBSD 4.8, (that's what the p2 means), but I'm not sure 
whether your version is completely up-to-date.
