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.

While generating the huge report getting Java Heap Space Error

Hi All,
We are using XML Publisher 5.6.2. we have to generate the huge report which contains more than 300 sql statements. Since our schema structure we can not reduce the queries. Now we are facing issue while generating the report. It takes lot of time and gives 'java heap space error'. We are using data template and RTF template for generating excel report.
Can anybody help me to resolve the issue? or is there any other way to generate the huge reports?
Thanks,

Hi,
I had seen the forum, but we had already adjusted the parameters in the oc4j "-XX:MaxPermSize=128m -Xmx512m" values to 4096. but still we are getting the java heap space error. since we increased the size of xmx value, XML Publisher occupies 61% of memory of the server. B'coz of this our other applications are getting affected.
and also, since we are using XML Publisher 5.6.2, can you please assist us how to set the scalable property to 'true'.
Thanks,
Ramya.

Flash Builder 4.5 Java Heap Space Error

Hello everyone,
I've downloaded Flash Builder 4.5 trial a few days ago. Let me first tell that I like the new features a lot and they help to speed up the development process noticably. I thank Adobe for that very much.
However I did not notice any performance boost over the Flash Buidler 4. Even worse, the 4.5 version seems to run much slower and use more memory than Flash Builder 4. I constantly keep getting Java Heap Space errors and needles to say, the tool just crashes and I have to restart it.
Here how my experience working with the new version looks like. I start the Flash Builder 4.5 which has my current project open (for the record, I still use Flex 4.1, and the project includes roughly 300+ classes and 30000+ lines of code (AS and MXML)). At the beggining everything works fine and pretty fast. UI, code completion, snippets and all other good stuff works pretty fast. However, after each build, FlashBuilder.exe process eats up from 50 to 100 megabytes of memory and does not seem to release it or reuse it. So after a 5 or 10 builds it already appears to be using over 1 GB of RAM. At that point the editor becomes sloppy - it can't keep up with my typing, code completion popups takes a few seconds to show up. And a few more builds - the Flash Builder freezes and after a minute or two I get Java Heap Space error.
I've tried increased the JRE heap space used by the Flash Builder (flashbuilder.ini, flashbuilderc.ini, eclipse.ini) to -Xms512m -Xmx1024m as well as permanent generation heap space to -XX:MaxPermSize=512m -XX:PermSize=256m and the mxml compiler (jvm.config) to -Xms384m -Xmx768m. However this did not solve the problem. Maybe just postponed it a bit.
Am I the only one observing such behaviour of Flash Builder 4.5? Does any one have any other ideas how to fix this? (by the way, I work on 64bit machine with Widnows Server 2008R2, 4GB of RAM and 2.66 GHz Intel Core 2 Duo).
Thanks in advance.
Michael

I'm seeing nearly the same thing. I also have a very large set of projects similar to what you are describing and I do have Java Heap Space errors (The details show an error of "java.lang.OutOfMemoryError: unable to create new native thread" occurring for me)
I had similar issues, although they are more frequent in the 4.5 builder, in the 4.1 builder. In 4.1 builder, I didn't get the exact same detailed error regarding threads.
I did install my flash builder into a clean instance of eclipse 3.6.2 vs using the standalone install. That shouldn't make a difference though. In 4.1, I tried he standalone install and saw the same issues I saw in the plugin version.
I'm also using the 4.1 SDK in Flash Builder 4.5 (It appears that is what you are doing). I've been attributing the crashes to the following bug in the 4.1 SDK, although I have applied the files in the bug report and still have the problem. I'm hoping when I'm able to switch to the 4.5 SDK it may help. (I can't switch yet because from what I can tell, it requires 10.2 Flash Player and my company is currently only on 10.0)
The Bug Report I'm referring to is: https://bugs.adobe.com/jira/browse/SDK-26366
I've bumped up all of the memory settings you've referred to and it helps the environment run longer, but it still eventually crashes. One thing I definately do is make sure that the "Build Automatically" is unchecked.
The machine I'm running on is an Intel 2600K with 16GB of memory running Windows 7 64-bit, so I don't think hardware is the issue.
No real answer, but your not alone in having similar issues.

How to increase java heap space on BIEE 10.1.3.3.1

Hi All,
I am using BIEE 10.1.3.3.1.
while doing bursting i am getting java heap space error. how can i increase java heap space.
Please anyone explain how to increase .. its very urgent
Regards

Yes, but I have not one, but TWO configurations.
One configuration named StateTEDSTest points at the DataSource named teds_proxy_tedsdev_dasis8. Another named StateTEDSProd points at the DataSource named teds_proxy_teds_dasis8.
What you seem to be saying is that I should only have one configuration, point it at a DataSource named, say, teds_proxyDS, then make teds_proxyDS reference the test database on the test application and the production database on the production application. I agree that that would probably work, but it negates any benefit of being able to define more than one configuration.
What I asked is, how do I tell one deployment to use the configuration named StateTEDSTest, and another to use the configuration named StateTEDSProd?
Looks like I'm not the first to ask this - see this thread:
basic deployment question
Unfortunately, no answer there either.

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.

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,

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"?

Where to change/set the memory size in config file. I am using tomcat 6.0, when i start to browse my application i am getting this error. But this error is not coming on all the systems which we work ,only on one system I am getting this type of error. What should I do. If there is a memory leak how to find it out?. our application user very huge memory and we cannot change/reduce the code. this is the error

I think this can't be issue with following variables:As I hv set them from 64m to 256, still issue coming.
WLS_MEM_ARGS_32BIT=-Xms200m -Xmx256m
MEM_PERM_SIZE_32BIT=-XX:PermSize=200m
MEM_MAX_PERM_SIZE_32BIT=-XX:MaxPermSize=256m
Any suggestion.
Thanks,
Nitin.

making it 512 temporarily working fine, but my concern was something must have been eating all the memory.
I did run bcc with 128 MB and deployed lots of initial data too, didn't face the issue in recent past with same versions and same build size.
ATG:10.2
Weblogic: 10.3.5
JDK:1.6.0_25
One more info:
my build size is around 200 MB
I m not running productionAgent,But I didn't make that essential while setting agent.
Can that be issue that some Manager trying to hit the server continuously and eating the memory.
Can not running the agent server, eat substantial memory?

"java.lang.OutOfMemoryError: Java heap space" while trying to read Excel.

Hi Experts,
Here is my query. I'm trying to upload excel data into database table. This excel contains more than 20000 records. I'm storing this data in a vector after reading it & passing this vector as a parameter to another method(not mentioned in the below code) which writes into the database. The code works for records <4000, but fails to read beyond that & throws exception as below.

HOW did you increase the heap space? As that is the only solution you have in this case really.
It is a known fact that POI can use up a lot of memory for big spreadsheets. If at all possible, I would try to switch to plain text comma separated files / tab delimited files. If you cannot do that, I would try to put a size restriction on the sheets that your application will process to get rid of the heap space risk. A sheet can contain 20000 records, or four sheets can contain 5000 records; in both cases you process the exact same data, but at only 25% of the total memory usage.

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.

How do I stop "Exception in thread "main" java.lang.OutOfMemoryError.java heap space

I'm trying to rebuild my iPhone app, with hires graphics etc, using CS6 Flash Pro. However, I get this now,
Exception in thread "main" java.lang.OutOfMemoryError.java heap space ..... followed by a lot of location information related to the error.
Now, how do I increase the java memory allowances if that's the problem. I've already upp the jvm.ini file from 128 to 512. No difference.
I'm based on
Win8, 8GB RAM, x64
I'm obviously asking it to load a lot of resources - but hey, Flahs should be able to handle it right?
thanks if anyone can help

Hmmm. Maybe I was doing something wrong with images, and icons. I'm not sure, as it's not at all clear really.
This is the Icons screen from CS6, can't see the files above 512x512unless scrolling up - 29x29,57x57,114x114. no matter.
So - after reading and rereading the Apple specs and directions, I removed the 512x512 and the 1024x1024 images from the Icons list that get pulled in during build.
Next, I again re-read the Apple directives, and put the required files for the build into the base directory of the build, as per this image.
In actual fact - I can probably leave out the last two. iTunesArtwork.xxx But I don't know, because it is entirely unclear on that point. I can find no directive regarding this at all.
Do I upload them myself? Probably? I don't know.
HOWEVER.
The build now completes. Java, or something, was very confused about finding that file called 1024x1024.png in the build list, and would not do it.
Take it out of icons, built fine. Put it in the icons directory, and crash...
Now - with the setup I am using, it all builds fine for ipad and iphone, in all resolutions.
I don't know what the problem is with what Java is seeing, but this fixes it it seems.
Hope that helps anyone else.
cheers

Any one can help me?
Rgds.

Think about what happens in your program. If your program loads lots of data into memory of the AS (=heap) and you have lots of users, then you can get errors like this. The obvious solution is to start raising the heapsize, but you cannot do that anymore, since you're out of physical memory.
So with the information I have seen so far, in this case you either have to buy more memory, get less users or refactor your program.

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
