JAXB:  NPE on high load in Coordinator.java:112

Hello,
I'm using JAXB 2.0 and when running high load tests I get NPE.
In my code I have a static marshaller (initialized in a static initializer) and the method which makes use of it is synchronized.
Once every few (~10) invocations of my method I get:
java.lang.NullPointerException
at com.sun.xml.bind.v2.runtime.Coordinator.popCoordinator(Coordinator.java:112)
at com.sun.xml.bind.v2.runtime.XMLSerializer.close(XMLSerializer.java:752)
at com.sun.xml.bind.v2.runtime.MarshallerImpl.write(MarshallerImpl.java:272)
at com.sun.xml.bind.v2.runtime.MarshallerImpl.marshal(MarshallerImpl.java:200)
at javax.xml.bind.helpers.AbstractMarshallerImpl.marshal(AbstractMarshallerImpl.java:70)
Any help...?
Thanks,
Zohar.

  • Weblogic Thread hogging at  java.io.WinNTFileSystem.getBooleanAttributes at high loads

    Hi,
    At high loads, we are seeing that one WebLogic thread is active on a windows native call for quite some time.. I can see the following stack statements in thread dumps taken at 10 minutes interval. This has led to slow server performance. 
    This happens on WebLogic 10.3.2 that is hosted in Windows Server 64 bit 2008 Enterprise Edition SP1.
    The JDK used is JRockit jdk1.6.0_20-R28.3.2 (64 Bit)
    Also this happens at high user loads only and also irregularly.
    Our eclipse link versions are (Implementation-Version: 1.0.1-20080905, Specification-Version: 1.0.1)
    Any recommendation or pointer is appreciated.
    Now the thread dump details

    Any answers?????

    Hi,
    I have a similar issue on ODSI 10gR3 (WLS 10.3). I am having stuck threads - but, in my case it is clear that the database is down (not at the startup)
    Here is some more info:
    1. Test Connections On Reserve - Enabled
    2. Default values for other parameters
    Using Oracle thin driver for the connection pool "MyPool" -
    ./wlserver_10.3/server/lib/ojdbc6.jar
    My question is:
    1. How do I avoid the stuck thread caused when the database is down? During peak load, the stuck threads are causing some service requests to fail.
    I did my homework and the closest option I could find is set the statementTimeout (which is set currently to the default value of -1 i.e. never timeout). Oracle documentation (http://www.oracle.com/technology/software/tech/java/sqlj_jdbc/htdocs/111070_readme.html) says that the ojdbc6.jar supports setQueryTimeout() method.
    Is there any better way to attack this problem?

  • Querying the toplink cache under high-load

    We've had some interesting experiences with "querying" the TopLink Cache lately.
    It was recently discovered that our "read a single object" method was incorrectly
    setting query.checkCacheThenDB() for all ReadObjectQueries. This was brought to light
    when we upgraded our production servers from 4 cores to 8. We immediatly started
    experiencing very long response times under load.
    We traced this down to the following stack: (TopLink version 10.1.3.1.0)
    at java.lang.Object.wait(Native Method)
    - waiting on <0x00002aab08fd26d8> (a oracle.toplink.internal.helper.ConcurrencyManager)
    at java.lang.Object.wait(Object.java:474)
    at oracle.toplink.internal.helper.ConcurrencyManager.acquireReadLock(ConcurrencyManager.java:179)
    - locked <0x00002aab08fd26d8> (a oracle.toplink.internal.helper.ConcurrencyManager)
    at oracle.toplink.internal.helper.ConcurrencyManager.checkReadLock(ConcurrencyManager.java:167)
    at oracle.toplink.internal.identitymaps.CacheKey.checkReadLock(CacheKey.java:122)
    at oracle.toplink.internal.identitymaps.IdentityMapKeyEnumeration.nextElement(IdentityMapKeyEnumeration.java:31)
    at oracle.toplink.internal.identitymaps.IdentityMapManager.getFromIdentityMap(IdentityMapManager.java:530)
    at oracle.toplink.internal.queryframework.ExpressionQueryMechanism.checkCacheForObject(ExpressionQueryMechanism.java:412)
    at oracle.toplink.queryframework.ReadObjectQuery.checkEarlyReturnImpl(ReadObjectQuery.java:223)
    at oracle.toplink.queryframework.ObjectLevelReadQuery.checkEarlyReturn(ObjectLevelReadQuery.java:504)
    at oracle.toplink.queryframework.DatabaseQuery.execute(DatabaseQuery.java:564)
    at oracle.toplink.queryframework.ObjectLevelReadQuery.execute(ObjectLevelReadQuery.java:779)
    at oracle.toplink.queryframework.ReadObjectQuery.execute(ReadObjectQuery.java:388)
    We moved the query back to the default, query.checkByPrimaryKey() and this issue went away.
    The bottleneck seemed to stem from the read lock on the CacheKey from IdenityMapKeyEnumeration
    public Object nextElement() {
    if (this.nextKey == null) {
    throw new NoSuchElementException("IdentityMapKeyEnumeration nextElement");
    // CR#... Must check the read lock to avoid
    // returning half built objects.
    this.nextKey.checkReadLock();
    return this.nextKey;
    We had many threads that were having contention while searching the cache for a particular query.
    From the stack we know that the contention was limited to one class. We've since refactored that code
    not to use a query in that code path.
    Question:
    Armed with this better knowledge of how TopLink queries the cache, we do have a few objects that we
    frequently read by something other than the primary key. A natural key, but not the oid.
    We have some other caching mechanisms in place (JBoss TreeCache) to help eliminate queries to the DB
    for these objects. But the TreeCache also tries to acquire a read lock when accessing the cache.
    Presumably a read lock over the network to the cluster.
    Is there anything that can be done about the read lock on CacheKey when querying the cache in a high load
    situation?

    CheckCacheThenDatabase will check the entire cache for a match using a linear search. This can be efficient if the cache is very large. Typically it is more efficient to access the database if your cache is large and the field you are querying in the database is indexed in the table.
    The cache concurrency was greatly improved in TopLink 11g/EclipseLink, so you may wish to try it out.
    Supporting indexes in the TopLink/EclipseLink cache is something desirable (feel free to log the enhancement request on EclipseLink). You can simulate this to some degree using a named query and a query cache.

  • Error loading servlet: 'EbuController' java.lang.NoClassDefFoundError after redeploy EAR in weblogic 6.1

              Hi, there:

    We are using HP-UX 11.0 and the value for ulimit is unlimited

    Hi Everyone,
    Just thought I would give an update on this.
    While we're still deploying http://support.microsoft.com/kb/2733363/en-us to
    the remainder of our Windows 7 SP1 fleet, according to some Network Traces and XPerf that were sent to MS Support, it looks as though the issu with the Offline Files is now resolved.
    However, we are still having some issues with High CPU with the System Process in particular. Upon review of the traces, they have found a lot of ABE related traffic, leading them to believe that the issue may also be caused by ABE Access on our File Cluster.
    We already have the required hotfix for ABE on 2008 R2 installed (please see
    http://support.microsoft.com/kb/2732618/en-us), although we have it set to a certain value that MS believe may be too high. Our current value is set to "5", as that is the lowest level of any type of permission is set (i.e. where the lowest level of inheritance
    is broken).
    I think I will mark this as resolved regarding the Offline Files issue (as it did resolve the problem with the Offline Files)...
    Fingers crossed we can identify the rest of the high load within the System Process!!!

  • OSB: ArrayIndexOutOfBoundsException: 4080 on high load

    Hello,
    I have a problem with the OSB 11.1.1.6. When I call services in the OSB with a certain load, I get the exception below. If I call the same services one by one (no high load), everything works. I didn't have this problem in the OSB 11.1.1.5.

    Hi all,
    I found the area to support Oracle reported a bug for this problem. I applied the patch and the problem was solved. The problem occurred when the BS called an external url in https.
    The bug id is 14747231. Below is information about the bug.
    *** Symptoms ***
    With Certicom, the communication between OSB and external service is working fine. When they enable JSSE, they observe errors like the below and communication is failing:

    *** Cause ***
    If the ChunkedInputStream contains a Chunk chain having a non-null chunk and the end size is 0, ChunkedInputStream does not handle the chunk correctly. This issue is addressed by Bug 14747231, which introduces new logic to handle this condition.
    *** Solution ***
    Apply the patch. https://support.oracle.com/epmos/faces/ui/patch/PatchDetail.jspx?patchId=14747231

  • FD leaks on high load in JBOSS using Selector

    We observed FD leaks when our application is moved from Geronimo to  JBOSS. Ours is a multi-threaded application getting a response from UDP server.
    We were using Selector and DatagramChannel. we saw FD leak on high load. But when I removed Selector usage, the same does not leak any FDs.
    Is there any known issue in JDK?
    Thanks

    JBoss and Geronimo both run on top of Java.
    Obviously if you are using the same Java version for both then it is unlikely to be a JDK problem.
    If you are using a different version then there are too many variables to determine the cause.  So reduce the number of variables by using the same Java version.

  • Struts not good for high-load requests?

    I need a small advice from somebody with experience writing high-load web applications. I worked in Java servlets and was doing a bit in Struts but this is my first bigger project without working in the team so now need to decide the technology.
    I have to do the J2EE project that has simple business logic but will take some time for database and I/O operations and the maximum number of users is expected to be big, a few hundreds of them in the same time. Struts + Hibernate combination is very comfortable for working but am now confused may I use it for this purpose because I heard that Struts' action is single-threaded. If action is single-threaded, does it mean that hundred requests will make a queue and wait for each other's I/O processing completely finishes before getting next request? If so, then I shouldn't use Struts but ordinary servlets, right?
    Any hint will be very useful, thanks in advance!

    Same problem here (I also do panoramas).
    Actually I can't even import my files into Aperture.
    Other, slighly smaller, files (PSD or TIFF) show similar problems than yours just that my Previews or Thumbnails decide to turn blue, displaying the "Unsupported format" message - after sometimes weeks of working fine.
    But anyway, most of my files are usually too large to save out from Photoshop as PSD or even Tiff. PSB is unfortunately not supported by Aperture (according to the tech specs) and Aperture cannot indeed see the .psb files …
    I shall hope that larger files in general and the large file format will be reliably supported by v3 (likely out right after Snow Leopard).
    My current workaround:
    For processing large size files I avoid Aperture altogether anyway, using Bridge/Photoshop (+ Photomatix and/or PTgui) instead.
    Frankly, for me this combination works pretty well.
    The final image will be saved out as HiQuality JPEG for Aperture, solely for the purpose of file management.
    That JPEG will be stored in the same folder as the .psb and the other files (braketing and/or pano images). So by using "Show in Finder" I can quickly find the Photoshop original.

  • Itunes wont load due to java scriptcore.dll what do i do, itunes wont load due to java scriptcore.dll what do i do

    Suddenly itunes stopped loading. I uninstalled it and tried to reinstall it but it wont load saying the Java sript core.dll is not valid. What do i do to fix this? And will i be able to get my downloads back?

    Taken at face value, you're having trouble with an Apple Application Support program file there. (Apple Application Support is where single copies of program files used by multiple different Apple programs are kept.)
    Let's try something relatively simple first. Restart the PC. Head into your Add or Remove Programs control panel, select "Apple Application Support", click "Change" and then click "Repair".
    If no joy after that, try the more rigorous uninstall/reinstall procedure from the following post. (Although the procedure is for Vista and 7 and you've got XP, just read "Computer" as "My Computer", read "Uninstall a program control panel" as "Add or Remove programs control panel" and assume the system is 32-bit, and you'll be doing the right things.)
    Re: I recently updated to vista service pack 2 and I updated to itunes 10.2.1 and ever

  • OEM High Load Widget -- does it work with Windows 7?

    The README page for the OEM High Load Widget ( http://www.oracle.com/technetwork/oem/grid-control/emgridcontrol-10-101399.html ) does not list Windows 7 as a supported O/S. Has anyone been able to get it to work on Windows 7 (64-bit)?
    My new PC at work is running Windows 7 64-bit O/S. I've had good luck in getting everything I was running on my previous Win XP SP3 machine but the OEM High Load Widget is not connecting.
    I have found that widget to be quite useful and really would like to be able to use it.

    Yes,http://manuals.info.apple.com/en_US/time_capsule_4th_gen_setup.pdf

  • 2008 R2/ Win7 Offline Files Sync causing High Load on server

    Hi Everyone,
    I have recently been investigating extremely high CPU Usage from the System Process on my company's main File Cluster.
    We managed to track SRV2.sys Threads causing high CPU load within the system process, but was having issues identifying why this was the case.
    As per Microsoft's direction via support call, we have installed the latest SRV2.sys Hotfixes, but this does not appear to have allivated the issue we are experiencing. We have also added more CPU and Memory into both nodes, which has not helped either.
    We have since managed to create a system dump and is being sent to MS Support for analysis.
    I have noticed the following that appears to happen on our cluster:
    Whenever our CAD/Design department run certain functions within their apps running on a windows 7 client (apps include MicroStation, Revit, AutoCAD etc) we see a massive spike and flatline of the system process.
    We found several users with Windows 7 clients that have Configured Offline File to sync an entire Network Volume (some volumes are 2TB Plus, so would never fit on a users computer anyway, i was quite shocked when I found this). How we spotted this was through
    Resource Monitor, the System Process was trolling through all the folders and files in a given volume (it was "reading every single folder). Now, while this was the system process, we could identify the user by using the Open Files view in Server Manager's
    Share and Storage Management tool.
    I have done a fair bit of research and found that a lot of CAD/Drawing applications in the market have issues with using SMB2 (srv2.sys). When reviewing the products that we use, I noticed that a lot of these products actually recommended disabling SMB2
    and reverting to SMB1 on File Server and/or the clients.
    I have gone down the path of disabling SMB2 on all Windows 7 clients that have these CAD Applications installed to assist with lowering the load (our other options are to potentially shift the CAD Volumes off our main file cluster to further isolation these
    performance issues we have been experiencing.) We will be testing this again tomorrow to confirm that the issue is resolved when mass amounts of CAD users access data on these volumes via their CAD Application.
    We only noticed the issue with Offline Files today with trying to sync an ENTIRE Volume. My questions are:
    Should Offline File sync's really cause this much load on a File Server?
    Would the the size of the volume the sync is trying to complete create this additional load within the system process?
    What is the industry considered "Best Practice" regarding Offline Files setup for Volumes which could have up to 1000+ users attached? (My personal opinion is that Offline Files should only be sync of user "Personal/Home" Folders
    as they users themselves have a 1 to 1 relationship with this data.)
    Is there an easier way to identify what users have Offline Files enabled and "actually being used" (from my understanding, Sync Center and Offline Files are enabled by default, but you obviously have to add the folders/drives you wish to sync)?
    If I disable the ability for Offline Files on the volumes, what will the user experience be when/if they try to sync their offline files config after this has been disabled on the volume?
    Hoping for some guidance regarding this setup with Offline Files.
    Thanks in Advance!
    Simon

    Hi Everyone,
    Just thought I would give an update on this.
    While we're still deploying http://support.microsoft.com/kb/2733363/en-us to
    the remainder of our Windows 7 SP1 fleet, according to some Network Traces and XPerf that were sent to MS Support, it looks as though the issu with the Offline Files is now resolved.
    However, we are still having some issues with High CPU with the System Process in particular. Upon review of the traces, they have found a lot of ABE related traffic, leading them to believe that the issue may also be caused by ABE Access on our File Cluster.
    We already have the required hotfix for ABE on 2008 R2 installed (please see
    http://support.microsoft.com/kb/2732618/en-us), although we have it set to a certain value that MS believe may be too high. Our current value is set to "5", as that is the lowest level of any type of permission is set (i.e. where the lowest level of inheritance
    is broken).
    I think I will mark this as resolved regarding the Offline Files issue (as it did resolve the problem with the Offline Files)...
    Fingers crossed we can identify the rest of the high load within the System Process!!!
