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 when Saving SequenceFile generated using API

I am currently developing an application that creates a SequenceFile using .NET 4.0, C# (2010), Windows 7 Pro x64, Dual Core 2.5 GHz, 3.0Gb Memory. Using the API EngineClass, I create a complete SequenceFile based on user/file inputs and then save it to disk. When I'm done, I save using SequenceFile.Save() and then release using ReleaseSequenceFileEx().
For smaller files, there is no problem. For larger files, I sporadically get the following error:
System.Runtime.InteropServices.COMException (0xFFFFBD98): Out of memory.
When the file does save, it is ~2.8Mb. Breaking the file up is not an option. I am not looping, this is one shot. I've tried shutting down VS2010 and restarting the computer. It is still inconsistent on saving.
I also had to set the Embed Interop Types to False per guidance from NI. They said that it is unstable in 4.0.
Questions
1. Is there a file limit size to the Save() API function?
2. Is there a workaround to using the Save()?
Best Regards
Solved!
Go to Solution.

I am using C#.NET. I called them in my save method immediately prior to the actual test save sequence.
GC.Collect();
GC.WaitForPendingFinalizers();
GC.Collect();
GC.WaitForPendingFinalizers();
try
       CurrentSequenceFile.Save(outputPath);
       catch (Exceptionerror)
       FireLogEvent(ParserLogType.Parsing_Error, string.Format("{0}", error));
Factory.TSEngine.ReleaseSequenceFileEx(CurrentSequenceFile, ReleaseSeqFileOptions.ReleaseSeqFile_UnloadFile);
Hope this helps

Out of memory errors

I'm having problems starting 8i. When started from /etc/rc.d/
init.d/dbora during bootup or manually by root, I get an out of
memory error.
If I start it from the dbadmin user (oracle), I either get the
same out of memory error, or I end up with several hundred shell
logins and the database still doesn't respond.
This is RedHat Linux 6.0, kernel 2.2.5-22smp. Here is a sample of
what happens when I get the out of memory error:

6532K buff

It turns out that the problem I was having with a large number of
shell processes being created was due to the use of oraenv in my
.bashrc file (so much for following the instructions!) It was
calling itself recursively until the process limit was reached.
However, even with this fixed, the out of memory error still
exists.

Out of memory error, Urgent!!!

Hi All,
I know there have been a lot of posts for this topic, but none of them seem to address my problem. So please help me out!!! I have written an GUI application that if you open and close for up to certain times, say 10 times, then you will get OOM. I have set the objects to be null when closing the application and called System.gc() as well as System.runFinalization(). Note that I can't call System.exit(0) since this application is not a standalone one. I thought in java if the objects are not used any more, then they will be garbage collected. I may not even have to set the objects to be null. But obviously there are still references to these objects in memory.
I am really frastrated. I read about SoftReference, but I don't get the error while running the application. So I don't think it's very useful for my case.
hhh

>
You probably still have references to the objects
somewhere.
The variables you've set to null, aren't the only
references.
Is there a way that I can find out what referencesare
still alive after I exit the application?
After you exit the application? After you exit
the application, there are zero references, and also
it's impossible to get out of memory errors from java
after it exits.
But I think you may be using the word "application" or
"exit" incorrectly here...
What do you mean you don't get the error whenrunning
the application?I meant I don't get OOM error while running
application. I simply launch the application andthen
exit it. By doing so for about 10 times, then I get
the OOM error. But that's impossible. After the JVM exits, the JVM
can't throw an out of memory error. It can't throw
any errors. It's not running anymore.As I said in my original message, my application is not a standalone one. It is actually one of the tools out of the main application. That's why when I exit this tool I can't use System.exit(0) to stop JVM.

Indesign cs5 'out of memory' error when using preflight

I have been regulary getting an 'out of memory' error when i choose to use my bespoke preflight profile.
I have 4gig of ram and run Indesign CS5 on OS 10.6.8.
Does anyone know a work around?
As soon as I select from the basic default profile, i get the beach ball from hell for 10mins, then it kindly lets me know that I am out of memory, sends a crash report to Adobe and then asks if I want to relauch. I'm stuck in a vicious circle. I must of sent my 4th crash report now and no feedback from anyone at Adobe.

I have replaced my preferences, but still the problem persists. I have tried switching my view from typical display to fast display before i selected a profile. I thought this may give me the extra memory I needed to avoid the enevitable crash. I learnt that 2 files were indeed rgb instead of cmyk before it crashed again. So I switched them to cmyk and tried again, selected my bespoke profile, but yet again it crashed. I think the problem lies with the file, not Indesign, as i have tried the same profile on a different file and the program doesn't crash and runs as it should. So if in future I need to use said crashing file again, firstly i will need to try Peter's isolate fix method. Otherwise i'll never be able to progress to successful a pdf.

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.

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?

Hi Rogier,
Can you please log it in our new public bug system:

It'd be great if you can provide more info to the bug e.g.
details of your simple AIR project, platform, FB version (Plugin or
Standalone).

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

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
the current scheme, files larger than 17-20MB throw an out of memory
error. is there any way we can get around this problem? i will post
the client and server side code for reference.
Client Side Code:

// to server. This client connects to a servlet running on the server

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.

U0093Critical program error occurred .u0093Client out of memory error u0093 - Query

I have a problem with Query in BI 7.0
Query works perfectly in BW3.5 environment. BI 7.0 Vista and Excel 2007 environment I have date range in the query If I provide date range 4 months interval it is working fine.
If I provide 5, 6,7, months interval I am getting the error ,
Critical program error occurred .The program has to close. Please refer to the trace for further information.
Communication error, CPIC return code 020, SAP returns code 223
Client out of memory error
When I execute each interval this query and calculated the no of records it is only less than 19,000 records.
The same query working fine in Bw3.5 for more than year interval.
Advance Thanks .

It depends on the ssytem settings. The problem with your query is that it is not able to fetch all the data due to lack of memory. However, when you are giving smaller range, you are getting the output. You can either ask the basis guy to increase the memory space or try running the query by giving smaller date range. You can have some filters on your query also.
Thanks...

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.
regards,
