>Description:
NFS mounts to a local SCO box are locking up processes in sbwait.  Can
reboot, do various find and ls, will lock up process pretty quickly.
Cannot kill, Ctrl-T shows "load: 0.08  cmd: ls 304 [sbwait] 0.00u 0.00s
0% 336k".  During this I can still access same mounts to SCO on old RH
Linux server right next to it that I'm trying to replace.
>How-To-Repeat:
Mount a directory over nfs and do some read activity, locks up within a
few minutes.  I'd be glad to provide more info if I know what to look
for.  Don't know if related to talking to the SCO server, but RH Linux
box has talked to it for several years.

 Got it working, don't know if it was a parameter problem or I simply
 sidestepped
 a bug.  In fstab, I originally supplied the "rw" option.  I threw all of the
 following
 options at it in desparation: "rw,-2,-a0,-b,-i,-r1024,-w1024" and it's
 solid.  I might
 tune these options later, but at least I'm able to move forward.
