I thought I had MFC'ed the fix to releng_6. Maybe I did not :(. Sorry... I don't know if it is too late to get this into 6.1 or not. cc:ing re: for his comments. This is a pretty serious bug, and if there are last minute fixes being accepted, I would like this to go in. Unfortunately, cvs.freebsd.org seems to have changed from what I was familiar with. Now that website displays some perforce nonsense, which I can't grok. I am trying to see if there's a link someplace where I can see cvs comments. mohan --- Kris Kennaway <kris@obsecurity.org> wrote: > I don't know if mohan already committed it, so perhaps he can comment. > > Kris > > On Fri, Sep 29, 2006 at 10:10:02AM +0200, Yuri Khotyaintsev wrote: > > Will a fix for NFS/TCP (nfs_socket.c rev 1.138) be ever committed to stable? > > > > Yuri Khotyaintsev wrote: > > >On Monday 08 May 2006 19:41, Kris Kennaway wrote: > > > > > >>On Mon, May 08, 2006 at 01:54:58PM +0200, Yuri Khotyaintsev wrote: > > >> > > >>>I have an NSF server and several clients which write large text files to > > >>>the server.
