[comp.sys.sun] Sun Killer

era@niwot.scd.ucar.edu (Ed Arnold) (08/11/90)

When someone said the IBM RS/6000 is a "sun killer", they meant it
literally.

We have an RS/6000 that had a filesystem on a 4/280 running 4.0.3 remotely
mounted, and when it blasted NFS UDP packets to the 4/280 at maximum
speed, all of the nfsd-s (eight of them) froze into permanent wait states.
This required a full reboot of the 4/280.  The 22 client users were ever
so pleased.

Has anyone run into this problem?  If so, have you been able to get a
solution/patch from Sun?  Please reply via e-mail to me, will summarize if
I receive any info.

Thanks to the following persons for pointing out that I really ought to
apply the "4.0.3 NFS jumbo patch" before giving up on mounting files from
a 4/280 on an RS/6000 (which regularly hangs the 280's nfsd-s):

sinclair@strider.sps.mot.com (Brian Sinclair)
jayl%sputnik@bit.UUCP (Jay Lessert)
ehrlich@colossus.cs.psu.edu (Dan Ehrlich)

This is a BIG patch (about 35 separate bugids) whose Patch-ID# is 100091-01.
It's available via anonymous ftp from psuvax1.cs.psu.edu:~ftp/pub/sun-fixes,
files Jumbo.NFS.Patch.README and jumbopatch.tar.Z, if you don't have sun
support.
