Java memory error

Upon starting weblogic get error: AIX RS/6000 5.o WebLogic 6.1 sp2 -
Unable to initialize the server:'Fatal initialization exception Throwable: java.lang.OutOfMemoryError: ZIP004:OutOfMemoryError, MEM_ERROR in inflateInit2

java.lang.OutOfMemoryError: ZIP004:OutOfMemoryError, MEM_ERROR in inflateInit2This looks like zip deflating occurs (probably a jar file of some sort), then
the heap is exhausted during execution, and the JVM reports java.lang.OutOfMemory.
What are your JVM options? For example, -Xms and -Xmx. I believe under IBM's
1.3.1 JVM on AIX, you're limited to a maximum possible Java heap size of 2.5 GB
(that's after also setting maxdata to 0x00000000 to free up all 10 consecutive
segments (0x3 -0xC) for mmap( ), per IBM documentation here:
http://www-106.ibm.com/developerworks/eserver/articles/JavaPart2.html
Also, review your swap space on your filesystem (increase if necessary). Hope
this helps!

Java Memory error for applprod

Hi,
I have strange problem. I am running "Create accounting" program and it errors out with the error message
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
I have sun SPARC servers, with 16GB RAM, 38 GB SWAP WITH 12.1.1 and 11.1.0.7
So following the note
Troubleshooting Java[tm]: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. [ID 1260764.1]
The funny thing is
when i run the command java -Xmx2048M -version it works fine on root and oraprod. But when i run in applprod it throws the same error
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.
I have checked ulimit settings, they are fine
1) ROOT:
root@server1 # ulimit -a
core file size (blocks, -c) unlimited
data seg size (kbytes, -d) unlimited
file size (blocks, -f) unlimited

stack size (kbytes, -s) 8192

2). ORAPROD:

If i run java with 1024M it works fine as follows

Please any help.
Thanks

Hi Hussein,
I created another user test1 of group dba and ran java -Xmx2048M -version. It worked with out error.
Then i found the only difference between test1 and applprod is ulimit -s set to unlimited in applprod but not set in test1
I removed ulimit -s unlimited for applprod the executed
java -Xmx2048M -version
it worked fine.
But i guess ulimit -s unlimited is a pre-requisite for running R12 in solaris??
What shoud i do
Please suggest.
What does "echo $ADJRIOPTS" return after sourcing the env file?bash-3.00$ echo $ADJRIOPTS
-mx512m
bash-3.00$
Thanks

JDeveloper 10.1.3.3.0 Java Memory errors

Hello,
I have been developing an ADF Application that contains a tree component that is used for navigation of a BOM structure. The BOM is not that large only 600 or so records and when I am testing for short intervals I have no problems. When the application is run for extended periods 15-20mins in both the embeded oc4j container and the Application server 10.1.3.4.0, it runs out of memory and in the case of the application server the instance is restarted.
I have tried to limit records retrieved, increase heap memory to ridiculous sizes (1024MB), configure the AM pooling settings and still this occurs. I guess I have memory leak or something but I tried to use JDeveloper debug functions to isolate and cannot find. Does anyone know how I can make the app release memory and stop restarting the application server? Any tips on how to find memory leaks?
Any help is greatly appreciated.
Thanks in advance,
Peter

This issue had to do with a known bug in the Java Hotspot sever and updating the version of Java to 1.5.0_17-b04 resolved this issue.

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

Java Out of Memory Error

Hi,
I'm running a Java app that's been working perfectly for 12 months. I did the latest Java upgrade from Apple and I now have heap space errors. The result of running Java version is as follows:
java version "1.6.0_20"
Java(TM) SE Runtime Environment (build 1.6.0_20-b02-279-10M3065)
Java HotSpot(TM) 64-Bit Server VM (build 16.3-b01-279, mixed mode)
The error listing is below. I'd be grateful for any help in setting memory in the .sh file that I use to launch the app or for other ways to resolve this.
A search of this forum yielded no assistance on this.
Regards
Mike

How to figure out the size of an object - java out of heap memory error

Hi all,
I am using an object that I found in a library that I didn't create so I don't know its internal state or members.
I created a single one of these objects and I call announce() on this object which just sends a UDP announcement over the channel to notify listeners. However, after a message #124,288 I get a java out of heap memory error.
I am wondering if this announce() method is causing the state of the object to grow with every call...it seems unlikely but I want to check to see if it's reserving a growing amount of heap memory without ever allowing it to free.
My question is how can I check how big the object is within my program? I'd like to check, for instance, at every 10,000 messages sent how much memory the object is taking up. Is there a method call for that? Would I have to use some kind of debugger or memory monitor? I would like something easy to use.
Please let me know, and thanks in advance.
Julian

Thanks for the quick reply.
I say it's unlikely that the methods I call are filling up heap memory because I have one Message object. This one Message has a myMsg String member. Whenever I want to change the message I call myMsg = "anewstringhere". And then I do myMessageObject.announce(); And for that reason i say I only have one Message object. The only thing added to the heap would be the strings that I replace myMsg with. The old references to myMsg are no longer valid and should be garbage collected..
Unless of course if you are calling intern() on them.
so here's my train of thought (and this isn't what my actual code looks like):
myMessageObject.myMsg = "hello" //creates a string on the heap? I assume this is equivalent to saying myMsg = new String("hello")No they are not the same.
The text literal will be in the intern space. Both code fragments would do that.
The second example would create a second instance of String(). That second instance would be cleaned when no longer referenced. But the literal will not.
Is my thought process correct? You are calling a third party library right so mock it (write a simple replacement that does the minimal correct functionality.) Substitute it in your code. And then run. If it still fails then the problem is in your code. If not then it is either in the library or the way that you use the library.

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:

the OOM error ... wasn't coming when we had set min and max both as 4 GB.You deviously withheld that information.
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 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.

I had tried using -Xms / -Xmx options (upto 1 GB).
The trace of exception gets delayed (from being displayed on the console) as the memory size is increased; but after sometime it starts getting displayed on the console.
Even though this exception is displayed on the console, the Timer Bean continues to execute upto sometime before it finally crashes!
If anyone has encountered such problem; would appreciate if you could share the solution.

Hi guys, I have the same problem. I have an application EAR file with two modules (EJB and WAR starting in this order). The application can schedule a process via EJB timer. In this case restarting the server I receive the error above. If I change the modules start order --> WAR - EJB the server start correctly, but the application scheduler fails (the persistency is not working) with this error:

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

I have a java applet that needs to upload files from a client machine
to a web server using a servlet. the problem i am having is that in

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?

Help with Java Memory Leak in URLConnection

Hi everyone,
I can't seem to find the memory leak in the below code, if anyone could help, i would greatly appreciate it. The jist of the code is: I open up a URLConnection to update a ColdFusion page that takes in URL parameters passed in my URL. Then, I get the response. I also check for proxy usage and take that into consideration when making the connection.
I have one class to handle the Connections, Connect.java:
     * Connection using Username and Password, as well as boolean option to use Basic Proxy Authentication
     public Connect(String pHost, String pPort, String urlString,
                         String pUsername, String pPassword, boolean useProxy) {
          this.pHost = pHost;
          this.pPort = pPort;
          this.urlString = urlString;
          this.pUsername = pUsername;
          this.pPassword = pPassword;
          this.useProxy = useProxy;
     * Get the Input Stream from the Connection given a specific URL
     public java.io.InputStream getInputStream(String urlString) {
          if (urlString == null) urlString = this.urlString;
             exDialog = new ExceptionDialog(new javax.swing.JFrame());
          try {
               String auth = "";
               if (useProxy) {
                    System.getProperties().put("proxySet", "true");
                    System.getProperties().put("proxyHost", pHost);
                    System.getProperties().put("proxyPort", pPort);
                    String authString = "";
                    if (pUsername != null && pUsername != "") authString = pUsername + ":";
                    else authString = "username:";
                    if (pPassword != null && pPassword != "") authString = authString + pPassword;
                    else authString = authString + "password";
                    auth = "Basic " + new sun.misc.BASE64Encoder().encode(authString.getBytes());
               java.net.URL url = new java.net.URL(urlString);
               java.net.HttpURLConnection conn = (java.net.HttpURLConnection)url.openConnection();
               if (useProxy) conn.setRequestProperty("Proxy-Authorization", auth);
               conn.setRequestProperty("User-Agent", "Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 5.0)");
               conn.setDoInput( true );
               conn.setDoOutput( true );
               conn.connect();
               return conn.getInputStream();
          } catch (java.io.IOException ioe) {
               exDialog.showForThrowable(ioe.toString(),ioe);
               return null;
     }I call the code in Download.java:
Connect conn = new Connect(sm.pHost, sm.pPort, null, sm.pUser, sm.pPass, sm.useProxy);
new BufferedReader(new InputStreamReader(conn.getInputStream(sUpdateURL)));
in.close();For some reason, as I loop through this call, the memory footprint of my program grows through every iteration, eventually resulting in a Java Out of Memory error. I can't track the leak down and it's fairly frustrating. If anyone can help, that would be greatly appreciated. Thanks!

One place there might be a memory leak is in the line
exDialog = new ExceptionDialog(new javax.swing.JFrame());Even though the JFrame object goes out of scope when the ExceptionDialog method returns, JFrames stay around until they are closed, even though in this case it isn't even shown on the screen.

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.
