I have received helpful explanations and suggestions regarding almost all
questions I had listed in my original posting on the above subject. Below
I include a condensation of the answers to each question.
>We get the following two messages:
> le0: WARNING: if_snd full
Might be attributable to network problems such as broadcast storms.
> zs0: silo overflow [or:] zs1: silo overflow
Nobody commented on this one -- I take that to mean that I shouldn't loose
sleep at nights over it.
>and recently this gem:
> itrunc: /usr/71999 new size = 0, blocks = -16
Opinions vary here as to the severity of this one. cs at eng.sun.com takes
the dimmest view:
= This one's serious. Are you still running some flavor of 4.0* instead
=of 4.1? [yes] If so, a patch is available. [...]
=If you're seeing this on 4.1 (where it's supposed to be fixed), report a high
=severity bug today. Really. It's your file system we're talking about here.
I'm getting in contact with my local Sun support organisation.

The solution is to use the format(8S) (/usr/etc/format) and select the
Repair-command. Reboot afterwards as the problem was in the swap area.
Documentation is in the section "Repairing a Defective Sector" in Chapter
10 (Maintaining Disks with format) in the System Administration manual.
I did this, and it seemed painless. I would like to thank the people that
sent me mail in answer to my questions. They were:
cs at eng.sun.com (Carl Smith)
del at mlb.semi.harris.com (Don "Truck" Lewis)
levy%ihcgf%tellab5 at relay.eu.net
[ sorry, but that was all that was left of the address ]
