I don't know what is returning ENXIO, but putpages just calls the filesystem VOP_PUTPAGES entry, so you'd have to look at that. vnode_pager_putpages isn't usually called very often in a typical system - it's used when mapped/modified file pages need to be written back to the backing file, which doesn't normally happen on a typical system (modified pages are usually backed by swap, not the file). >Looking through /usr/src/sys, the error message is generated in >vm/vnode_pager.c...which, to me, would indicate swap space? No, the swap_pager pages out to swap. The vnode_pager pages out to files. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
