Can someone look at this? This is pretty weird, it seems that somehow there's some deadlock with vnode locks, but it doesn't appear to be due a leaked vnode lock as "show lockednods" doesn't show any vnodes locks.
The trace should be somewhat easy to figure out but I'm kinda of stuck.. Any ideas how this could happen? -Alfred ----- Forwarded message from Lin Jui-Nan Eric <[email protected]> ----- From: "Lin Jui-Nan Eric" <[email protected]> To: "Alfred Perlstein" <[email protected]> Cc: [email protected] Subject: Re: Process stuck in STOP state Date: Fri, 26 Dec 2008 12:41:12 +0800 Message-ID: <[email protected]> Hi, Full back-trace is located here: http://aqua.pixnet.tw/~jnlin/textdump/event3/1226/ On Fri, Dec 26, 2008 at 11:34 AM, Lin Jui-Nan Eric <[email protected]> wrote: > Hi, > > No, NFS is not working (df hangs, and cd /nfs/vol hangs, too). we have > run fstat and see some NFS file is opened. > I will do a full back-trace while this happened again.
