>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.
