In earlier versions of Eclipse (pre 3.1) my JVM continually crashed when loading up Sakai projects. Changing my startup min max memory settings appears to have righted the good ship Eclipse so I thought I would share my experience.
To change Eclipse's default min and max memory size settings, edit the file eclipse.ini. Editing this file represents a change from earlier versions of Eclipse, where startup settings were stored in Info.plist. Indeed, Info.plist includes the warning note:
| No Format |

<!-- WARNING:
If you try to add a single VM argument (-vmargs) here,
*all* vmargs specified in eclipse.ini will be ignored.
We recommend to add all arguments in eclipse.ini

Finding
...
eclipse.ini
...
is
...
a
...
wee
...
bit
...
tricky.
...
To
...
locate
...
it,
...
right-click
...
on
...
the
...
Eclipse
...
Application
...
icon
...
and
...
select
...
"Show
...
Package
...
Contents",
...
then
...
double-click
...
on
...
the
...
"Contents"
...
folder
...
and
...
then
...
double-click
...
on
...
the
...
"MacOS"
...
folder,
...
the
...
home
...
of
...
eclipse.ini.
...
You
...
can
...
then
...
edit
...
the
...
settings
...
as
...
I
...
did
...
below
...
setting
...
the
...
min
...
and
...
max
...
memory
...
settings
...
according
...
to
...
your
...
evaluation
...
of
...
what
...
your
...
system
...
requires.
...
You
...
can
...
also
...
startup
...
eclipse
...
from
...
the
...
command
...
line
...
with
...
appended
...
-vmargs
...
arguments
...
but
...
I'll
...
leave
...
it
...
to
...
others
...
to
...
outline
...
that
...
procedure.
