Netbeans profiler and "java.lang.OutOfMemoryError: Java heap space"

I have a swing application. When I run this program, I get java.lang.OutOfMemoryError: Java heap space periodically.
I am using the netbeans profiler to figure out how my heap size is increasing and whether or not I have any memory leaks. What I see is that I have lots of int[] getting generated. When I take the snapshot and look at the allocation stack traces, I cannot find the packages in my code at all. I see classes in java.awt.image.*, sun.awt.image.*, javax.swing.*, etc., but nothing referring to the classes I have developed. What could be wrong and how come I do not see anything referring to my code so that I can fix it?

Take a look here.
It seems that you may have a similar situation. If you read through, you'll see that the number of surviving generations gives an indication of where to look.

Servlet.service() Error. java.lang.OutOfMemoryError: Java heap space

Hi All,
I would be very grateful if you would draw some light for this error I got from running a online database connected image viewer (applet).
The application is quite simple, applet connect to servlet, servlet send 3 SQL statements to MySQL and retrieve image info (Strings) and 50 Files (- JPEG image) from a online database, and then pass all of data to applet from servlet. The size of total of images is around 3.5 MB, and I've increased JVM memory to 128 MB by using code "-xmx128m".
? Do I need send images from servlet to applet individually rather than push them in one go
? Is there memory leak in my codes
Please see the codes below:

wire the code into a simple unit test, then run a profiler on it to see where the memory is going. You need the help of these kind of tools to track down memory issues, before that it is only guesswork what might be soaking it all up.

i searched the net and it seems that i should increase the java heap size , how can i do that... I have a server with 4G Ram ..

My frien google tells me that you use
>
Exception in thread "main" java.lang.OutOfMemoryError: Java heap space
This can have two reasons:
* Your Java application has a memory leak. There are tools like YourKit Java Profiler that help you to identify such leaks.
* Your Java application really needs a lot of memory (more than 128 MB by default!). In this case the Java heap size can be increased using the following runtime parameters:
java -Xms<initial heap size> -Xmx<maximum heap size>

Getting java.lang.outofmemoryerror: Java heap space error

I am using coldfusion 8. I frequently get the error 'java.lang.outofmemoryerror: Java heap space'. Can anyone help me?
Error Details :
500
Root cause:
java.lang.outofmemoryerror: Java heap space
javax.servlet.servletException: Root Cause:
java.lang.outofmemoryerror: Java heap space
Thanks in advance,

Satheesh.

Well... what does the error message tell you is wrong? You're running out of memory. I presume you understand how computer memory works, if not specifically how Java memory allocation works. So... you have x amount of memory, and you're trying to use >x amount of memory. You can't do that. There are two approaches to dealing with a problem like this:
a) have more memory;
b) use less memory.
What are your JVM memory settings? They're in jvm.config dir, which'll be - by default - in your Jrun4/bin dir for a multi-server install, or somewhere like ColdFusion/runtime/bin or something like that on a stand-alone install.
Next... what are you loading into memory? This is trickier to answer. But every variable you create takes up memory. People often load up the application or session scopes with stuff that's "convenient" to store in shared-scope memory, but really chew through it. Putting CFC instances in the session scope is a really good way to waste memory, as they seem to have quite a large footprint.
It's really impossible to say what's eating the memory based on what info you've given us (basically: none), but you can use things like FusionReactor to examine what's going into memory. Or CF* Enterprise has some of its own memory profiling stuff... I've never used it but it might be of some use.
Have you googled "coldfusion java.lang.outofmemory"?

One app service getting "java.lang.OutOfMemoryError: Java heap space"

We are running a commercial app on WebLogic 9.2. Two physical servers with 5 application processes running on each in a single cluster. on the server in question, we have 5.5 gigs of free ram at the moment and still getting the message below.
We have 10 app servers and one is getting this message. the full text of it is:
####<Apr 13, 2011 10:58:12 AM CDT> <Warning> <DeploymentService> <lxwbwapa> <workbpr2_node_1a> <[ACTIVE] ExecuteThread: '6' for queue: 'weblogic.kernel.Default (self-tuning)'> <<WLS Kernel>> <> <> <1302710292663> <BEA-290064> <Deployment service servlet encountered an Exception while handling the deployment service message for request id "-1" from server "Admin_pr2_a". Exception is: "java.lang.OutOfMemoryError: Java heap space
".>
I dug back through the logs and found it started a couple of weeks ago. I have been able to log into this app server without issue.
Something else I have noticed is that the total heap size for all the app services have shrunk from the initial value of 1.5G - they have all dropped down into the 500 meg range. Is this normal? Why has this one not increased the size of the heap if it is running out of memory?
I could restart the service for this app server but I would not know the cause and since it is a production server where I am not recieving complaints, I am hesitant to go through the res tape to do a re-start.
Any information or past experience with this type issue is greatly appreciated.
Thanks,
W

Hello,
You might want to post this in the weblogic forum: WebLogic Server - General
as they might be able to explain how WebLogic uses or releases resources.

I'd suggest pre-compiling the application before deployment.

I'd suggest pre-compiling the application before deployment.

Trouble with "java.lang.OutOfMemoryError: Java heap space"

Hello,
I use a Java-based modeling tool that very few out there are probably familiar with. This tool allows me to run models (program) from within the development environment, to create Applets or create jar files that can be executed in a stand-alone fashion.
I am using a database on my local harddrive to read in some data using JDBC, so am not using the Applet option with certificates. The development environment is expensive, so can't be distributed. That leaves the stand-alone option.
The model (program) I've written runs perfectly fine in the development environment and, previously, has worked fine as a stand-alone program. However, the stand-alone option isn't working anymore, because I keep getting this error.
I am not much of a Java programmer; I'm learning as I go along. If anyone can help me solve this, I'll be most appreciative
From my cmd prompt:

Hi I am ancountering the same problem with the 'heap space'.
Is there any way I can find out what it is set to for my system? I dont believe its 32Mb and dont want to increase it randomly to too large a size if theres no need for it.
Thanks,
Bobby

Java.lang.OutOfMemoryError: Java heap space

I am writing an application in struts for file downloading from the database. I am using struts 1.1 with tomcat5.0 server. File downloading is working fine for images of smaller sizes( i checked utpo 3mb of size). my application should download the files with a maximum 1gb size. But when I tried to download the image of 85mb, "out of memory" exception is thrown" and this is the complete trace of that exception...

Dbca errors out with java.lang.OutOfMemoryError: Java heap space

hi gurus
I am trying to use DBCA to create a 10.2.0.4 database on a HP platform.DBCA hangs at the step 6 and following message can be seen in the
trace.log:
java.lang.OutOfMemoryError: Java heap space
I googled and modified the DBCA scripts content from
# Run DBCA
$JRE_DIR/bin/java -Dsun.java2d.font.DisableAlgorithmicStyles=true -DORACLE_HOME=$OH -DDISPLAY=$DISPLAY -DJDBC_PROTOCOL=thin -mx128m
-classpath $CLASSPATH oracle.sysman.assistants.dbca.Dbca $ARGUMENTS
to
# Run DBCA
$JRE_DIR/bin/java -Dsun.java2d.font.DisableAlgorithmicStyles=true -DORACLE_HOME=$OH -DDISPLAY=$DISPLAY -DJDBC_PROTOCOL=thin -mx256m
-classpath $CLASSPATH oracle.sysman.assistants.dbca.Dbca $ARGUMENTS
and rerun the DBCA and the problem still there.
How to solve this problem?
Thanks !

i have a huge XML file of size 9 MB. I need to parse it and store it in a MYSQL database. When i execute the program, it throws me out of memory error and only 12668 rows have been inserted into the database. I use SAX parser to parse the XML. i have also given the stack trace of the error below. Kindly let me know how to resolve the issue.
I have also changed the JAVA_OPTS to -Xms128m -Xmx512m but this didnt solve the issue.

Check your code where u set the connection query; there's a procedure in my DBConnection class, looks like this:
public void setQuery(String query) throws SQLException {
this.query = conn.prepareStatement(query);
Should look the same for u, at least similar.
I set the query this way: dbConn.setQuery("insert into groups (id, code, sectionID, languageID, year, no_students) values (?,?,?,?,?,?)");
I had to insert 24,827 records into a table, and it throws the heap space exception u mentioned when it reaches 12,667. So what i did was to put dbConn.setQuery(...) outside the loop, and inside the loop it remains to set the parameters and execute the query from connection. It works for me. Hope will help u save some memory space.

Exception occurs on startup: java.lang.OutOfMemoryError (Java heap space)

Dear All,
I am trying to use JDeveloper 10.1.3.0.4 (SU2) on Windows XP SP2. My machine is almost new and has 2.5 GB of RAM and 2 processors with 3.0 GHz each. Should be enough, right?
When I try to startup JDeveloper, I am often getting an exception java.lang.OutOfMemoryError: Java heap space. At other times, I see that JDeveloper is using an awful lot of virtual memory - e.g. 590 MB. Then at least, JDeveloper opens normally, but it's not stable at all.
I guess, there's something in the workspace - created in JDeveloper 9.0.5 and now migrated - that I am trying to open that is giving trouble, because in the lower right corner I see a message "scanning sources". This message does not want to go away. JDeveloper continues to scan. When I try to edit, I get a light blue screen after some time and JDeveloper hangs. What is happening?
Kind regards,
Dobedani

Increasing the memory in this case won't help at all.
The constructor of MyFrame creates an object of type WrapCheckers3D.
The constructor of WrapCheckers3D creates an object of type MyFrame.
This leads to an infinite recusion of object creation that fills your memory heap. You need to get rid of that recursion.
Usually you'll get another exception in that case (namely a StackOverflowError), but you get a OOM-Error, probably because you create big objects during the recursion.

How to solve this ERROR --java.lang.OutOfMemoryError: Java heap space

I am Trying to read one TEXT file line by line. file size is approx. 7 MB or it contain approx. 35000 line of text.
i am processing that file and export data into another file.
mean while after some line i get error like below,
java.lang.OutOfMemoryError: Java heap space
After this error process stop.
my application is in Java Swing and i m using java 1.5 version of SDK and JRE.
is it a JDK version Problem?
please can any one give me appropriate solutions for this.
give me answer please.............

Are you able to post the code you use to read the file? Initially, I'd guess that you're stuck in a loop. Make sure you're getting out of all your loops. You can do this with breakpoints in your IDE's debugger, or by putting a println right after the loop.
It may also be that your IDE isn't allotted enough of your system's memory, though I doubt that is the case. You can easily google how to increase the memory allotted to the IDE.
For some reason, garbage collection isn't happening as you're expecting. Make sure you're not holding on to huge stuff any longer than you need to.

Server SSLSocket + java.lang.OutOfMemoryError: Java heap space

Hi guys,
I have problem with SSLSocket on server, sometimes when client try to connect to server "java.lang.OutOfMemoryError: Java heap space" error appear. I have created SSLServerSocket then in loop socket is listenig and waiting for accept a client.
    private SSLServerSocket mSocket = createServerSocket(port);mSocket is ok, problem must be somewhere in code below:
    private Socket acceptSocket() throws IOException {
        SSLSocket s = (SSLSocket) mSocket.accept();
        s.startHandshake();
        return s;
    }Where can be problem ?
Thanks a lot
/zippos
