Jrun service restart problem

Question

I have began to get an error after installation of Java
update 1.4.2_02 jre. (It was an auto update)
It currently runs with 1.4.2_02 SDK as a service. After
starting to get the error, I uninstall the update but it still
continues.
After restarting computer, it starts the server without
problem.
While tryign to restart server with Admin Tools->Services
it gives the error (-2)
Error reported in logs:
Error occurred during initialization of VM
Could not reserve enough space for object heap
I have done some research but nothing is useful for my
problem.
jvm.config hasnot been changed. but here is the arguments.
java.args=-Xms32m -Xmx128m -Duser.language=en-US
-DJINTEGRA_NATIVE_MODE -DJINTEGRA_PREFETCH_ENUMS
-Dsun.io.useCanonCaches=false
btw, it has 2gb ram.
I have read using "-server" in the wrong place could result
this situation but it doesnt use it.

Answer 1

It seems the application uses another config file not to
waste resources with admin application as it is explained here(
http://mkruger.cfwebtools.com/index.cfm/2006/4/17/multiserver)
here is the arguments it actually reads:
java.args=-server -Xms1000M -Xmx1400M -XX:NewSize=256M
-XX:MaxNewSize=256M -XX:MaxPermSize=140M -Xss128k -Xincgc
-Dsun.io.useCanonCaches=false -Duser.language=en-US
It does a lot more sense now, however I cant still figure it
out, what has been changed because of the update?? It might not
allocate the space -1540M max with MaxPermSize- because of lack of
memory however there were not any of this a few days ago.
thx for quick replies tzimmerman
