Memory limit for Java decresead to 1412 Mb

[Pierre Joly]

Dear all,

Since yesterday the memory limit for the Java virtual machine on my
computer with windows XP SP2 has decreased from 1600 Mb to 1412 Mb. The
only change seems to be an update of Microsoft Office (2003 SP3) done on
all computers of our site. I have reinstalled ImageJ together with Java and
the new limit is unchanged.
Does somebody have a clue ?

Pierre,

I understand that the JRE will only make available to ImageJ the memory
that it can reserve from the operating system; could some bloated
program be running in the background, reducing what the OS can allocate
to the JRE?  Check the Windows task manager (Windows key + R, type
taskmgr, hit enter) Processes tab, Mem Usage.

Which Java version are you running (Help->About ImageJ)?

Hi,

i cannot (yet) reproduce this, as I use ImageJ with the built in JVM and a
fixed limit of 512 Megs

(sorry for the silly question, where can I easily read these numbers you
are referring to?)

BUT the latest XP update seems to have cause other strange things as (not
really a big but strange issue....)
it made the Media player disappear from the Quickstart area as also from
the Program menu (it´still
on the computer, though)

First I thought this is probably due to a new company policy  to avoid
people "wasting time" during work hours....

Mit freundlichen Grüßen / Best regards
