Re: [K12OSN] Help VNC crash w/firefox



I recall a lot of discussion about 6 months (or maybe a year) ago about
Firefox causing thin clients to crash when many tabs were open.  I think it
boiled down to images that Firefox loads get cached by the X server, and
once the X server is out of RAM it crashes.  You have only 4 MB for your X
server, so it is crashing instantly (images on your home page use up all 4
MB, perhaps).

Have you tried other browsers?  I'm not sure if it's a Firefox thing or if
all browsers will behave the same.
