Actually, as I think of it, I think the vnode pager would also be the
part used faulting pages in and out of mmap()'d files, which could
point at the database. Memory pressure from that wouldn't result in
swapping, since clean pages would just get tossed and dirty pages
would be synced and tossed.
In that case it may not be so much a 'problem', as just 'normal' for
your case, and your actual problem may be somewhat elsewhere.
