Probably short of memory. I've _only_ 1GB which used
to be quite ok for a laptop.
AFAIK, the warning message is wrong. Although all
memory is in use, the system should be able to
shrink some caches to free memory. But b131, b132
TCP got this wrong and enters defensive mode, and
I think this could affect network connectivity.

Now trying to upgrade to b133 and hoping for the
best, it just dies in the same way, whaterver trick I
try (gui, pkg cmd line, text mode...)
Does it freeze during the b132 -> b133 upgrade?
Or did the upgrade succeed, but the upgraded b133 freezes
in the same way b132 did?
The "WARNING: Memory pressure: TCP defensive mode on"
message should be gone in b133...

So am I forced back to reinstall ?
Do you have a b130 (or older) BE? Maybe you could activate that
and upgrade directly from b130 to b133, avoiding bug 6910378 ?
Well,
it freezes during the "Creating plan" when running pkg image-update,
either from b131 be or b132 (I kept both).
it freezes during the "evaluating SUNWgcc package" when trying to ugrade
from gui
Unfortunately I destroyed my b130 be so I cannot try it.
I know the memory pressure msg is not directly related, but I can see
the memory being eaten up when running vmstat, untill it freezes.
That is up to a certain point because as image-update runs with a quite
high priority, console output tends to be very slow and erratic (which
in my opinion is very wrong, you should NOT get unresponsive shell when
running an update).
Thanks for your help
Bruno
PS : I must say it never happened with my homle server and 8Gb mem, so
ram seems to help ;-).
