With -Xmx951M Eclipse fails to start [message #326959]

Thu, 03 April 2008 13:05

Europa 3.3.2 on Windows Server 2003 with 4GB physical memory, 3GB
available.

Setting -Xmx to any value above 950M causes Eclipse to fail to start.

The following eclipse.ini works:

-showsplash
org.eclipse.platform
--launcher.XXMaxPermSize
512m
-vmargs
-Xms40M
-Xmx950M

but with -Xmx951M or greater, I get a popup "JVM teminated. Exit code=-1"
as soon as I launch Eclipse. A search of the entire Eclipse directory
structure turned up no files matching *.log.

Suggestions on how to debug?

There is a practical limit to the maximum heap space setting that a JVM
can actually satisfy. It is related to how the JVM allocates that memory
(IIRC, it requires a contiguous block, which may or may not exist
depending on the state of your OS memory at the time).
Here is a little info about it:
http://www.eclipsezone.com/eclipse/forums/t94023.html#921445 85
There are other (more complete) references on the web, but I don't have
time to dig them up right now.

If that is indeed the problem you're bumping into, there is nothing
Eclipse can do about it.

Hope this helps,
Eric

What JRE are you using?

Are you sure?

Although as Eric said there's a practical limit, I routinely run
with -Xmx1024M on Sun JDK 1.5.0_13 and 1.6.0_u5, so I don't think 951M
should be a problem. I wonder about that 512M for max perm size, though,
that seems like an awful lot.

ISTR some compatibility issues between Windows Server 2003 and the Sun JDKs?
Sorry, it's a very vague recollection; you might try checking the Sun web
site for more info on OS compatibility.

I am using -vmArgs -Xmx1000M to start M6 and this is working for me.

Which JVM are you using?
I am using j2sdk1.4.2_08 from Sun

That may be part of the problem, as the JVM will be trying to allocate
two large contiguous blocks of memory, 950MB for heap and another 512MB
for perm gen. Jim, can you try bumping down the perm gen setting to
256MB (or even 128, which is usually enough even with a large tool set
like Eclipse+EMF+GMF+WTP)?
