This is most likely a symptom of the `losing memory' problem.  The
pages are still in core, and are associated with the object, but since
they're no longer on a paging queue, they're not eligible for being
garbage collected by the pageout daemon.  Thus the object may never
lose all its pages, and will stick around, keeping the vnode open.

I haven't checked, but it's also possible that the bug could have
caused memory corruption in some cases (e.g. if something later
treated the page as if it were on a queue, and tried to remove it
again).

Anyway, glad to hear that it works for you now!
