Java heap out of memory error with -Xms1g -Xmx4g 64 bit VM

We are getting Java Heap memory error for the application we are running on linux 64 bit machine (VM).
The OOM came when heap usage was 1.7gb though we have specified min as 1gb and max as 4gb. If I understand correctly then it should not have been thrown as we have specified max as 4gb. If address space was the problem then it should have thrown swap space error.
Also, there were no other processes running on this node.
Below are the specifics of linux node we are using:

When the JVM needs to grow the heap it asks the OS for a bigger memory block than the one it has.
The OS may refuse this and the JVM will throw an OOME.

Out of Memory Error in Java Agents running in lotus notes

I have a java agent running inside lotus notes jvm. It runs fine for some days but after some days start giving out of memory error and terminates.
I need to restart agent manager in notes to enable java agent running. Is there a way to catch out of memory error so that on its catch i could restart agent manager.
Regards,
Saitu

Dear Peter,
The agent is written in java and
I need to know a way to enter catch block of 'OUTOFMEMORYERROR'.
My whole code is in a try block with two catches, one for outofmemoryerror and another for exception. When outofmemory error occurs control passes to the exception catch and not outofmemoryerror catch.
Since out of memory is an error and not an exception, is there a way to catch it or run some code when out of memory occurs.
Regards,
Saitu

Out of Memory Error While deploying as EAR file

Hai,
I was trying to deploy an EAR file of size 63 MB which inturn containing about 60 EJB.jars. No WARs. application.xml has all the entries for the JARs. While I am deploying it is giving Out of Memory Error. Is there any way to tweak this problem. I am using my own hand written java application which uses the SunONE deployment APIs for deployment. Can u please tell how to tackle this problem. I am running my application through a batch file which uses jdk1.4.
Please help me regarding this issue.

You can set the initial heap size and maximum heap size for the JVM, either in the app-server admin console, or maybe in one of your scripts. You look-up the syntax!...
I had this error yesterday. I too had run out of memory (150Mb). You simply need to allocate more to the app-server.

Uploading large files from applet to servlet throws out of memory error

OK - the problem you describe is definitely what's giving you grief.
The workaround is to use a socket connection and send your own request headers, with the content length filled in. You may have to multi-part mime encode the stream on its way out as well (I'm not about that...).
You can use the following:
http://porsche.cis.udel.edu:8080/cis479/lectures/slides-04/slide-02.html
on your server to get a feel for the format that the request headers need to take.

I get the out of Memory Error on the client side. I
was told that this might be a bug in the URLConnection
class implementation that basically it wont know the
content length until all the data has been written to
the output stream, so it uses an in memory buffer to
store the data which basically causes memory issues..
do you think there might be a workaround of any kind..
or maybe a way that the buffer might be flushed after
a certain size of file has been uploaded.. ?? do you
have any ideas?

JavaScript Out of Memory Error on Portal timeout.

Hello All,
I am using jsf and Inline navigation in all our portlets and when user leave the browser idle for portal timeout we have 2 problems. 1: Login portlet shows in that specific portlet. 2: we get a javascript alert saying out of memory at line 40. and the porltet shows error message as "Gateway was not able to access requested content. If the error persists, contact your portal Administrator."
We are using Plumtree 5.0.4 Java version.
any help is highly appreciated.
Thanks
A.J.

Both are valid behaviors unfortunately.
1) login portlet is showing up in specific portlet b/c inline navigation allows for you to create and load pages without affecting the overall portal.
This happens when you use iframes (which behave in a similar fashion).
- your only workaround is really to write some javascript function to "listen" to the portal login page getting loaded and then throwing the session into the parent browser (which is Portal). At least this is the only solution that I ever came up with when using Iframes.
2) Don't know about out of memory error actually, but getting the "gatewy was not able to access requested content" is valid b/c the session died.
- javascript errors require javascript solutions. Sorry I couldn't be more helpful than that.
Maybe someone else will have better suggestions.
The other suggestion is to use your app server to listen to the logout event and redirect appropriately to somewhere else, or have it do what you want it to do in situations as this.

Large Pdf using XML XSL - Out of Memory Error

Hi Friends.
I am trying to generate a PDF from XML, XSL and FO in java. It works fine if the PDF to be generated is small.
But if the PDF to be generated is big, then it throws "Out of Memory" error. Can some one please give me some pointers about the possible reasons for this errors. Thanks for your help.

ERROR [B3108]: Unrecoverable out of memory error during a cluster operation

We are using Sun Java(tm) System Message Queue Version: 3.5 SP1 (Build 48-G). We are using two JMS servers as a cluster.
But we frequently getting the out of memory issue during the cluster operation.
Messages also got queued up in the Topics. Eventhough listeners have the capability to reconnect with the Server after the broker restarting, usually we are restarting consumer instances to get work this.
Here is detailed log :
Jan 5 13:45:40 polar1-18.eastern.com imqbrokerd_cns-jms-18[8980]: [ID 478930 daemon.error] ERROR [B3108]: Unrecoverable out of memory error during a cluster operation. Shutting down the broker.
Jan 5 13:45:57 polar1-18.eastern18.chntva1-dc1.cscehub.com imqbrokerd: [ID 702911 daemon.notice] Message Queue broker terminated abnormally -- restarting.
Expecting your attention on this.
Thanks

Hi,
If you do not use any special cmdline options, how do you configure your servers/
brokers to 1 Gb or 2 Gb JVM heap ?
Regarding your question on why the consumers appear to be connecting to just
one of the brokers -
How are the connection factories that the consumers use configured ?
Is the connection factory configured using the imqAddressList and
imqAddressListBehavior attributes ? Documentation for this is at:
http://docs.sun.com/source/819-2571/ref_adminobj_props.html#wp62463
imqAddressList should contain a list of brokers (i.e. 2 for you) in the cluster
e.g.
mq://server1:7676/jms,mq://server2:7676/jms
imqAddressListBehavior defines how the 2 brokers in the above list are picked.
The default is in the order of the list - so mq://server1:7676/jms will always be
picked by default. If you want random behavior (which will hopefully even out the
load), set imqAddressListBehavior to RANDOM.

Out of memory error - from parsing a "fixed width file"

This may be fairly simple for someone out there but I am trying to write a simple program that can go through a "fixed width" flat txt file and parse it to be comma dilmeted.
I use a xml file with data dictionary specifications to do the work. I do this because there are over 430 fields that need to be parsed from a fixed width with close to 250,000 lines I can read the xml file fine to get the width dimensions but when I try to apply the parsing instructions, I get an out of memory error.
I am hoping it is an error with code and not the large files. If it is the latter, does anyone out there know some techniques for getting at this data?

I have tried to illeminate as many arrays as I can thinking that was chewing up the memory but to no avail.
Any thoughts or ideas?

You should not keep a String array of all the lines of the file read.
Instead for each line read, parse it, then write the parsed line in the other file:      public void loadFixedWidthFile() {
         BufferedReader in = null;
         BufferedWriter out = null;
         try {
            //File must be in same director and be the name of the string below
            in = new BufferedReader(new FileReader("files/FLAT.txt"));
            out = new BufferedWriter(new FileWriter("files/outfilename.txt"));
            String str;
            while ((str = in.readLine()) != null) {
               //System.out.println(str.length());
               str = parseThatLine(str);
               //write out the parsed str to another file
               out.write(str);
         catch (IOException e) {
            e.printStackTrace(); // At least print the exception - never swallow an exception
         finally { // Use a finally block to be sure of closing the files even when exception occurs
            try { in.close(); }
            catch (Exception e) {}
            try { out.close(); }
            catch (Exception e) {}
      }//end loadFixedWidthFile()Regards

Out of memory error on Hyperion Analyzer

When I tried to access a report through Hyperion analyzer HTML client, Out Of memory error comes up.I tried changing the virtual memory on windows 2000.Even then I am experiencing the same problem.Environment:Windows2000/Tomcat 4.04/IIS/Analyzer 6.2.1.Is there any parameter or setting to be set on properties file on App server side?Can anyone help me out of this problem?Thanks in advance.Jaya.

How much RAM do you have on the analyzer server. You may need more... In the mean time try adjusting these settingsThe analyzer_startup.bat or file can be edited to change the amount of memory allocated to the Java Runtime Environment (JRE). Instead of: set CATALINA_OPTS=-Xms128m -Xmx256m -Xss2mChanged to: set CATALINA_OPTS=-Xms256m -Xmx512m -Xss4mFor Tomcat, 1024m is the highest setting for Xmx.

Thread: Out of memory error

I'm running a program that reads a file of more than 20k lines. Each line of this file is being processed by a thread. Sometimes the program is being halted with the out of memory error.
What can I do to solve this problem ? Is it better to change the logic of this program and instead of calling a new thread for each line, call few threads to be responsible of processing multiple lines ?
The current java version is 1.4.2.13. Upgrading it to the most recent version can solve the problem ?
I'm running it with the following configuration:
"-Xms1024m -Xmx2048m -XX urvivorRatio=10"
Thanks a lot,
Marcos.

Indeed this design is flawed. It is an old system that came to my hands and now I have to fix some bugs on it.
What is the difference between calling thousand of threads and having this backport of concurrent to take care of it ? I mean, isn't the jvm responsible for managing the both cases ?
Using the backport of concurrent and defining a limited size thread pool, what will happen if the number of lines in the file is greater than the size of this pool ?
Do you have an example or a link to where I can get a good example on how to use it ?
Thanks for helping!

Loading JPEG/Gif images causes Out Of Memory Error

Hello Java gurus, please shed some light on this.....
I am not a java newbie, but I am a java newbie in the area of dealing with graphics. I am using JDK 1.4.2_01 on Win XP with 2.4ghz and 512 RAM. When I try to read in a (or a few) JPEG image into a JLabel using ImageIcon, I get an out of memory error everytime. This happens whether I am reading the image out of a jar file or out of a local directory. The JPEG's are 8.5" x 11", and range between 150kb to 900kb. I am trying to load approximately 10 images in a JTabbedPane using new JLabel(ImageIcon) on individual JPanels (one JPanel for each JPEG). Now I get the java.lang.outofmemory error whether I try to load 1 image or 10 images. Anyone got a clue as to what I am doing wrong? I actually do get one image loaded before the error gets thrown. So I do know that it is trying to load the right image. What is going on here? Is it an ImageIcon problem, or are there others who have run into this. It has brought this project to a grinding halt, and I had thought this would be the easier part!!!! Please help me out gurus! Thanks!

What options/values are you suggesting that I set? Or do you mean something else? Thank you for any ideas that can help me solve this problem. I never had any issues dealing with using ImageIcon for toolbar button graphics (file sizes of 1-3kb), but now with dealing with full page graphics I have run into a brick wall with this out of memory error.

Scaling images and Out of memory error

Hi all,
Does anyone knows why this code throws an out of memory error?
It loads an image (2048x1166 pixels) and saves it at bufi1 (BufferedImage). After that:
1- Rescale bufi1 to bufi13A (x3).
2. Rescale bufi1 to bufi12 (x2).
3. Rescale bufi1 to bufi13B (x3).
At 3, the code throws an oome. Why?
Thanks in advance!
import java.io.*;
import javax.imageio.*;
import java.awt.geom.*;
import java.awt.image.*;
public class TestScalePercent {
public static void main(String[] args) {
    TestScalePercent tsp=new TestScalePercent();
    BufferedImage bufi1=null;
    try {
      bufi1 = ImageIO.read(new File("foo.png"));//2048x1166 pixels
    } catch (Exception e){
      e.printStackTrace();
    BufferedImage bufi13A=tsp.scale(bufi1,3,3);//--> OK
    BufferedImage bufi12=tsp.scale(bufi1,2,2);//--> OK
    BufferedImage bufi13B=tsp.scale(bufi1,3,3);//-->OOM error!
public BufferedImage scale(BufferedImage bufiSource, double scaleX, double scaleY){
    AffineTransform tx = new AffineTransform();
    tx.scale(scaleX,scaleY);
    AffineTransformOp op = new AffineTransformOp(tx, AffineTransformOp.TYPE_NEAREST_NEIGHBOR);
    BufferedImage bufiop=op.filter(bufiSource, null);//--> Creates the OOM error...
    return op.filter(bufiop, null);
}

How much memory does your machine have?
That image is quite large. If my math is correct and
assuming the image has 32-bit color the original
image takes up 76.5 megs of memory by itself. Then
you are trying to create three other versions of it.
It isn't lying to you, it is indeed probably running
out of memory to hold the images.OK. Now I'm wondering if is it possible to free memory between bufi13A - bufi12, and bufi12 - bufi13B? I've tried to invocate the garbbage collector but nothing happens...
Thanks!

Out of Memory Error - JBOSS - JRocket

I continue to see my jrocket/jboss/linux servers crash daily in production for out of memory errors. When we trace back the stack to find a query that does not appear to have nearly enough data to bring the server to an out of memory state. Heap useage pattern does not indicate any leak in the application.
Using RedHat Linux ES - rel. 4 - Nahant Update 4
startup with 1536m Xms/x
Any thoughts or previous expereince. This is a Java application servicing a Flex UI

Check your Linux kernel version.
If you have an unpatched Linux kernel, which is not compliant, you will see these errors for all Jrocket.
The 2,6,9-5 kernel is not compliant without patches, see:
http://e-docs.bea.com/jrockit/jrdocs/suppPlat/prodsupp.html#wp999048
excerpt
The JRockit JDK is supported on the default Linux kernel, which varies with the distribution and architecture. See the Notes field in the Summary of Supported Configurations by Release for details. If you require a different kernel, such as the hugemem kernel, contact Oracle Support for current support status.
Also, see references to x_86 64bit?
http://jira.jboss.org/jira/browse/JBPAPP-158
This is a 32bit ES - rel 4 correct?

Out of memory Error with jdk 1.6

Hello,
I have a swing application launched on the client with the help of Java web start. The applications works fine in jre 1.4 and jre 1.5. The heap sizes are :
initial-heap-size="5m" max-heap-size="24m"
But when I run this using jre 1.6.0_05-b13, I am getting Out of memory Error, java heap size. And I see the memory usage is growing rapidly which I didn't notice in other jre versions (1.4 and 1.5).
Does anyone have any idea on this?
Thanks in advance,
MR.

Thanks for your response Peter. During my continuous testing I identified that error happens on jdk 1.5 also. And I have increased the min-heap-size to 24 MB and max-heap-size to 64 MB. But in that case also I noticed the out of memory error. The interesting thing is, the min-heap-size is never increased from 24MB and lot of free memory also.
Memory: 24,448K Free: 12,714K (52%) ... completed.
The Outofmemoryerror triggers from the reader thread which does the job of reading the data from the InputStream. One thing is we are continuously pushing more data on the output stream from the other end. Is that any limitation on InputStream which can hold some definite amount of data.
Please throw some light on this.
