rsync + hammer + nfs = trouble

:>     It sounds like a buffer cache deadlock, which should be easy for me to
:>     fix.  Were you reading from the NFS mount or writing to the NFS mount?
:
:Only rsync (via nfs) was accessing the filesystem.

:>     I'm assuming you are running the latest HEAD.  If so, please drop
:>     into the debugger (e.g. ctl-alt-esc) and generate a crash dump, and
:>     get it onto leaf so I can take a look.

:I am running HEAD from ~28h ago. Unfortunately, IIRC the machine doesn't have
:a dumpdev configured (yeah, I know). Is there any information I can get you
:via DDB?

    Try it with latest head, to make sure the bug is still there.

    I need to know whether rdist was reading HAMMER via NFS or writing to
    HAMMER via NFS, and what kinds of file structure was being copied?
    (big files, little files, hundreds of files, thousands of files.. what?).
