Hi ;

Recently my netweaver 7.0 always restart its j2ee engine , i check the log

it have a exception

Exception java.lang.OutOfMemoryError: requested 131072000 bytes for GrET* in /export/jdk142-update/ws/fcs/hotspot/src/share/vm/utilities/growableArray.cpp. Out of swap space?

no this file on my system!!!

and then the Java VM crashes ,

I have read the sap note 943602 mentioned in its log

my java - version is

java version "1.4.2_12"

Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_12-b03)

Java HotSpot(TM) Client VM (build 1.4.2_12-b03, mixed mode)

and

jstartup/vm/home = <jdk home directory>.

is in the right directory.

so , can give me solution to solve this situation???

Hi,

the error says that the application requested around 130 MB. of swap space - pagefile.

Indeed, the error can be related to the systemenvironment configuration

(system memory and system paging conditions). So how much memory is on the

server ? And how much swap space is configured ? Are there any other applications running

on this machine (unix ?) ?

thanks and kr,

andreas

Are you have 32 bit or 64 ? You need set : -- >

Hi , all Thanks!!!

I set up my netweaver in RHEL4 32bit.

Before i can change all this SDM or JVM setting

my netweaver wo`nt restart anymore

Since i really do not know how these happen

so i do`nt know why it work normally

i does not change anything yet

well , if (just if) this situation happen again

then i will test all these setting to see how it works

thanks.
