Well the client is definitely running out of memory. I swapped the 128MB stick for a
512MB stick, and now the first of the two sites loads fine pulling a whopping 78MB for
firefox according to xrestop. The second still freezes, but after pulling 427MB for
firefox. The websites I was trying are extremes posted by users who don't know how to
shrink a photo for the web, but made for great testing. At least now I know why the
client is crashing.
I was reading some stuff on this website:
about limiting the Video RAM for X. I am wondering if I can call on a custom xorg.conf
using parameters such as this:
Xorg forced size via the following configuration to force the size to 8MB:
Identifier "VIA Technologies, Inc. VT8623 [Apollo CLE266] integrated
However I am not sure if this will work. They also mention stuff here and other places
about using X_VIDEORAM = 8192 in xorg.conf to accomplish the same thing.....should that
work? I tried it with no luck.
Any other ideas besides ordering more RAM, I would have thought that 128MB was enough.
I did increase the NBD Swap size to 132MB as Scott suggested, with no changes at all
from the default 32MB. The correct size file is created in /tmp, but it does not appear
to be used by firefox...thoughts?
Any suggestions would be appreciated, at least I feel I know what the cause is now.
