The user was playing unreal tournament at the time and reported that it "got weird all of a sudden". I logged in and tried to do a ps, but the ps froze after listing a few lines. weird, never saw that one before. The user rebooted, so there was further opportunity to investigate, but I thought I ought to mention it after seeing these reports! jjs Aaron Lehmann wrote: > On Sat, Jan 27, 2001 at 03:34:26PM +1100, John Sheahan wrote: > > Hi > > my box has been running 2.4.1-pre10 for three days. > > This morning I noticed odd behavioue - ps and top wouuld freeze > > with no output. > > I had the same problem with 2.4.1-pre10 and the zerocopy patchset. > I came home one day and xmms was frozen.
