Strange Long ParNewGC Pauses During Application Startup

Recently we started seeing long ParNewGC pauses when starting up Kafka that were causing session timeouts:
[2015-04-24 13:26:23,244] INFO 0 successfully elected as leader (kafka.server.ZookeeperLeaderElector)

[2015-04-24 13:26:33,443] INFO New leader is 0 (kafka.server.ZookeeperLeaderElector$LeaderChangeListener)
After much investigation I found that the trigger was the allocation of a 500M static object early in the startup code.  It of course makes no sense that a single large static object in Old memory would impact ParNew collections, but, it does seem to.  I have created a bug report, but, it is still under investigation.
I have reproduced the problem with a simple application on several Linux platforms including an EC2 instance and the following JREs:
OpenJDK: 6, 7, and 8
Oracle: 7 and 8
Oracle 6 does not seem to have an issue.  All the ParNewGC times are small.
Here is the simple program that demonstrates the issue:
import java.util.ArrayList;
public class LongParNewPause {
   static byte[] bigStaticObject;
   public static void main(String[] args) throws Exception {
   int bigObjSize = args.length > 0 ? Integer.parseInt(args[0]) : 524288000;
   int littleObjSize = args.length > 1 ? Integer.parseInt(args[1]) : 100;
   int saveFraction  = args.length > 2 ? Integer.parseInt(args[2]) : 10;
   bigStaticObject = new byte[bigObjSize];
  ArrayList<byte[]> holder = new ArrayList<byte[]>();
   int i = 0;
   while (true) {
   byte[] local = new byte[littleObjSize];
   if (i++ % saveFraction == 0) {
  holder.add(local);
I run it with the following options:
-verbose:gc -XX:+PrintGCTimeStamps -XX:+PrintGCDetails -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -Xmx2G -Xms2G
Note that I have not seen the issue with 1G heaps.  4G heaps exhibit the issue (as do heaps as small as 1.2G)
Here is the output:

Even stranger is the fact that the problem seems to be limited to objects in the range of about 480M to 512M.  Specifically:
[503316465,536870384]
Values outside this range appear to be OK.  Anyone have any thoughts?  Can you reproduce the issue on your machine?

I have started a discussion on this issue on the hotspot-gc-dev list:
Strange Long ParNew GC Pauses (Sample Code Included)
One of the engineers on that list was able to reproduce the issue and there is some discussion there about what might be going on.  I am a GC novice, but, am of the opinion that there is a bug to be found in the ParNew GC code introduced in Java 7.
Here is a more frightening example.  The ParNew GCs keeping getting longer and longer - it never stabilized like the previous example I sent did.  I killed the process once the ParNew GC times reached almost 1 minute each.

  • After Effects can't continue: unexpected failure during application startup

    Im running 10.10, Mac OSX, it was running fine before a minor update came out, and now I can not open AE CS6. I have uninstalled, reinstalled it, installed the trial of CC 2014. No messages beside "After Effects can’t continue: unexpected failure during application startup" come up.

    Well, looks like a bug in Yosemite. You might wanan read the pertinent announcements, anyway. At this point Adobe apps are not compatible with OSX 10.10.

  • Timeout during application startup

    Hi,
              I am using WebLogic Server 9.1. I have a web module (web2.4) deployed and there is some time-consuming initialization in ServletContextListener.contextInitialized(..) method.
              The code requires about 7-8 minutes to finish and meanwhile, the module startup times out which show up as a failure status in the table of deployments (in WL console) and the web module is not accessible.
              Is there a way how to workaround this, e.g. by setting a timeout for the application/module startup or moving the code to another place (but it must be executed prior users can access the application) ?
              Thank you for any ideas.

    Hi JanGLi,
    The ODI Agent is completely failing to start here from the error that you initially pasted so agent tests are not going to work wherever you try them. Port 6550 should have something listening on it as that's the port that the FDMEE managed server listens on so that would only prove that the FDMEE managed server is up. I can't see the connection closed error having anything to do with running out of connections in the connection pool either as it's simply a message saying that a connection was closed (not that the connection pool is exhausted).
    On the plus side though I have seen the 'Servlet: "AgentServlet" failed to preload on startup in Web application: "oraclediagent"' error in the past (I get a lot of the really nice issues coming my way). Which operating system are you using here? I've seen this happen on Windows when there are multiple network interfaces and an incorrect interface has been put to the top of the bind order (e.g. an interface that has fallen back to a link local address in the 169.254.0.0/16 range as DHCP has failed).

  • Long pauses during ParNew garbage collection Please Help !

    Hi,
    We are running a server application on an large machine (~120 CPU, ~380 GB Memory).
    After running 1 or 2 hours we suddenly get exorbitant application pause times during garbage collection and a massive cpu usage from the java vm
    We are running on Java 6 (64Bit) with 6GB Heap.
    Concurrent garbage collection is turned on using the parameters:
    -XX:+UseConcMarkSweepGC
    -XX:+CMSParallelRemarkEnabled
    -XX:CMSInitiatingOccupancyFraction=80
    -XX:+DisableExplicitGC
    We turned on verbose garbage collection and are getting the following output:

    I can't find any significant differences in the log between fast and long running garbage collections.
    I urgently need help in solving this problem !
    What can I do ?

    After the exciting reply I did get on my question, we did some more investigations on the problem and it seems that we finally found the solution to our problem.
    The number of garbage collection threads used by the virtual machine defaults to the number of cpus of the machine.
    This is ok for small machines or machines where the main load is produced by the java application itself.
    In our environment the main load is not produced by the java application but oracle database processes.
    When java tries to do it's garbage collection using 120 threads (# CPU) on the machine which is already overloaded by non java processes, the thread synchronization seems to produce an exorbitant overhead.
    My theory is that spin locking is used on memory access, causing threads to spin while waiting for other blocking threads not getting cpu because of the heavy load on the system.
    The solution is now to limit the number of garbage collection threads.
    We did that on the first try by setting -XX:ParallelGCThreads=8
    For over one day with heavy load no long GC pauses were experienced any more.

  • Message bean does not start automatically during application server startup

    I have a message bean that does not start up during application server startup. I am able to successfully start the application manually using the visual admin tool.I searched the logs and found the following error. The error references the "QueueConnectionFactory" is not deployed or is not started. I have check and the "QueueConnectiopnFactory" is deployed. Is this a problem with the application trying to start before the "QueueConnectionFactory"? Is thier a way to define a dependency on my application not to start until the "QueueConnectionFactory" has been started, if so can how would I define this dependency. Please provide and example.
    Thanks,
    Bill

    I though the same thing, but XE LISTENER is running on localhost and port 1522. On the other hand XE have local_listener explicitly set to the very same connection descriptor. Even XE installation was second on this server.
    I've could change that yes, but the startup script doesn't seemed to have this mind.

  • Strange issue when pausing LONG audiobook--pressing play again changes the

    Strange issue when pausing LONG audiobook--pressing play again changes the position within the book--it doesn't start back exactly where it left off.
    The audiobook of "Harry Potter and the Half Blood Prince" is between 18 and 19 HOURS long--all as one long track/file.
    I've noticed that when I pause while listening and then press play again, it "rewinds" and starts playing portions of the audiobook from about 10 minutes prior--but the time stamp doesn't change. At least this is the time frame from the first "test". Other pauses/plays may result in different time differences.
    The first time this happened, I didn't realize what it was doing. I pressed play (from the pause) and I heard a portion that I had already played. I thought that the bookmark just didn't "remember" as it should have, so I scrubbed forward trying to find where I remembered leaving off. If you end up pausing/playing even a couple of times with this happening each time, the portion of the audiobook that you're playing and the time stamp becomes COMPLETELY off! For example, almost an hour into the time stamp was really only about 10-15 minutes into the actual book.
    I'm not sure if this makes any sense, but hopefully it does to someone. It's very frustrating to have this happen simply because you had to pause while listening. You have to scrub backwards or forwards each time to find out where you REALLY left off at and the time stamp becomes of no help value since it doesn't change as the playback position moves itself.
    I'm sure that this is something happening due to the extreme length of the audio file. That maybe it can't track as precisely as it could with shorter lengths. ???
    Any ideas? Has anyone else seen this happen? Any ideas on whether or not there is anything that can be done to prevent this?

    I'm glad that I'm not the only one having this
    problem. It's ironic that we're both having issues
    with the SAME audiobook. I haven't had a chance to
    listen to Books 1-5 much to see if they have the same
    issue or not--I don't remember any on the few parts
    that I've played for my nephews.
    Yeah, I know! I was shocked to see that. I recently finished HP5 (twice), and NEVER had this issue, but it is a much smaller file size.
    I'm thinking that I may try to convert to AAC before
    I try the splitting program--in theory, it's easier
    to start right back in again when you only have 1
    track to find, than when you have dozens/hundreds of
    smaller tracks. It's sometimes hard to remember
    which track you left off with--even if it's
    "bookmarked" within that track.
    I dunno anything about AAC, to be honest. Never used it. My plan is to split the MP3 into smaller MP3s by chapter and load them on a playlist. Of course, I will have to label them all nice and pretty. It is a long book, but you could always just load a couple of chapter files at a time. The only thing that I can see that would be kind of a pain about splitting it with the Cool MP3 is searching thru the file for each chapter and setting break points.
    My only concern is how much quality I'm losing by
    converting from one compressed format--MP3--to
    another compressed format AAC.
    Yeah. Ew. No clue. Sounds unpleasant to me. Again, I really do not do anything with AAC.
    I suppose, since it's
    spoken word instead of music, the change shouldn't be
    too noticable. I'm not sure what kind of time frame
    it'll require to convert. I'll probably try it with
    book 1 first--since it's the smallest.
    May depend on the program. The one I got boasts no quality loss. You may wanna scrounge around the download sites and see which one sounds like it has the best features, even if you do just get a free trial version of something. I would definitely read the editor's ratings. I tend to trust that more than the typical end user's. They show how many stars the editor gives a product, and you can click that for the review, or sometimes they have labeled tabs where you can access the review.
    As for how long it takes me to rip that particular file and if that actually fixes the scrubbing problem, I will have to let you know tomorrow. WAAAAY past my bedtime!
    Keep me updated on your end. I sure which that there
    was an explanation for why it happens.
    Will do! I am thinking you hit the nail on the head with the length. That was exactly what popped into my mind when I figured out what the goofy thing was doing.
    Talk to you later!

  • How to load objects in web application context during oc4j startup?

    Hi
    How I can put some objects in application context during oc4j application startup?
    I'm using oracle as10g j2ee and web cache edition.
    Thanks

    An idea would be to write your own OC4JStartup implementing class and have this thing create the objects you want and bind them to JNDI.

  • JSF: Problem during Tomcat Startup

    Hi, I am having a strange problem with a JSF-application.
    I am using jdk 1.3.1 (13), Tomcat 5.0.28 and the Sun JSF-Ref. implementation. On my dev-environment all is well. On the system-test environment of the customer, Tomcat would not initialize the FacesServlet claiming that it can not find the faces-config-file.
    I have tries all 3 ways of referencing the config-file (put it into a jar, put faces-config.xml directly into WEB-INF, add a context-param to web.xml with the URI of the file and param-name javax.faces.CONFIG_FILES). All three work fine on my dev, none of them works on sys-test.
    Funny enough, if I use the context-param in web.xml, where the web-app context is ctx, for the URI /WEB-INF/the-faces-config.xml I get an error during startup, for the URI /ctx/WEB-INF/the-faces-config.xml I don't have a problem on startup but the servlet does not actually read the config-file (you can tell from the fact that it can't resolve any of the Bean-methods).
    Any idea would be much appreciated!
    Cheers, Bastian

    Hi, thanks - unfortunately that did not help. The system (in the original configuration) does find the jars ok in WEB-INF/lib (I can tell since there is code in the jar which is executed before the problems hit me and the stack-trace when it can't resolve the bean-methods is from com.sun.faces.el.impl). It looks like the beans are not actually initialized (which is consistent, since the system can't find the config-file which wires the beans).

  • Front Row pauses during DVD play

    I've played at least 5 (3 of which were brand new) different DVD's in Front Row that randomly pause during play. After a few seconds the movie continues to play. I took the computer into the store to have the optical drive replaced, but it keeps happening. I tried just using DVD player and the same thing happens. Since the drive has been replaced, now I get "skipping over damaged area" when it pauses (only in DVD player). These are BRAND NEW dvds, there's no way they can be damaged already. Any ideas, suggestions, anything???

    That's interesting. Since it doesn't seem to be a hardware problem, you might use the Accounts System Preferences to create a brand new user. Log out and log in as the new user. Does the DVD Player application give you the same trouble when logged in as the new user? If not, then a preference or setting your original user has must be interfering. Or some kind of preference file corruption. If the new user does have the same trouble, it might be time to run the Disk Utility and make sure your permissions are repaired and the disk is repaired. If that still doesn't help, it may be time to do an "archive and install" of Mac OS X to get a good copy of the DVD Player application back...

  • Pre-loading the Cache from Database during application start-up

    We are using Spring, Hibernate, Oracle Coherence 3.5.2 Weblogic Webservices
    Our requirement is to pre-load the cache during the application start-up most probably during Authentication/Authorization Service is invoked.
    We plan to load the data for other services from database into Coherence cache so that whenever user access that particular service he ends up hitting the Cache instead of database.
    We would greatly appreciate sample code snippets on how to write CacheInitializerBean with marker to demonstrate the state of cache.

    Hi Rob,
    Thanks for pointing to the article: Pre-Loading the Cache
    In fact i already looked at that article before posting. It just mentions how to load the data from database into Cache.
    What i am looking for is how to make this happen during application start-up. This is my first hurdle.
    The second one is as mentioned in the article http://coherence.oracle.com/display/COH35UG/Pre-Loading+the+Cache
    i wrote following code which never gets populated into cache. Not sure whats going wrong even though i see Hibernate loadAll() method loading all the objects in the console
    public   void populateCache() throws SQLException
        Map<Long, Object>  buffer = new HashMap<Long, Object>();
        int count = 0;
         List<Contract> contractList = this.getHibernateTemplate().loadAll(Contract.class);
         log.debug("contractList size="+contractList.size());
         for(Contract contract : contractList)
             Long key   = new Long(contract.getId());
             Object  value = contract;
             buffer.put(key, value);
             // this loads 1000 items at a time into the cache
             if ((count++ % 1000) == 0)
                  contractCache.putAll(buffer);
                 buffer.clear();
         if (!buffer.isEmpty())
              contractCache.putAll(buffer);
        }We would greatly appreciate your time in helping us resolving two hurdle blocks.

  • Trying to create test project, and get NPE during server startup

    Hi
    I am trying to create simple test project using JSF RI (usually use myfaces), but I am getting a couple of NPE's during server startup.
    I am using :
    jetty (maven plugin)
    jsf 1.2_03

    This has been fixed in the RI head. Hopefully we'll be able to get a 1.2_04 out shortly.
    Please download a nightly from the RI project site and give that a shot.

  • Mail app during login/startup

    Sometimes when booting up my Macbook, the Mail app comes up during login/startup. I do not have an account configured, so the "Welcome to Mail" screen comes up, asking me to create an account.
    This does not happen all the time. Randomly.
    I do not have Mail in my login items.
    Any ideas why this happens and how i can make it stop?

    HI and Welcome to Apple Discussions...
    Well, if you don't have it set up in System Preferences/Accounts - Login Items then go to /Library/Startup Items and see if it's listed there.
    If you have a Dashboard widget that is related in anyway to how your Mac Mail application runs, that could be the culprit also.

  • Prevent long GC pauses

    Hello,
    I'm using jdk1.6.
    The problem is, that sometimes I'm facing a long gc pause, specially during "concurrent mode failure".
    Is there any option for jvm to set a max AppStopTime? And what could be the impact setting such a option ?
    Here are the jvm settings I'm currently using:
    -Xms4G -Xmx4G -XX:MaxNewSize=128M -XX:NewSize=128M -XX:MaxPermSize=256M -XX:PermSize=256M"
    -server -showversion -Xbatch -XX:+UseLargePages -XX:LargePageSizeInBytes=32M
    -XX:+UseParNewGC -XX:ParallelGCThreads=4 -XX:ParallelGCToSpaceAllocBufferSize=192k -XX:SurvivorRatio=6 -XX:TargetSurvivo
    rRatio=75 -XX:+UseConcMarkSweepGC -XX:CMSMarkStackSize=32M -XX:CMSMarkStackSizeMax=32M -XX:+CMSParallelRemarkEnabled -XX:-CMSClassUnloadingEnabled -XX:CMSInitiatingOccupancyFraction=80 -XX:+UseCMSInitiatingOccupancyOnly -XX:+DisableExplicitGC'
    Afaik there is no other chance to improve gc settings. Do you see any other possibilities ?
    Thanks,
    Christian

    Depending on how long lived the majority of the objects in your heap are you can better adjust the sizes of the new and old generation spaces. If short lived, make your new gen space larger. You could make it as large as half your total heap using "-XX:NewRatio=1". (NewRatio would replace using MaxNewSize)
    How do you know if objects are short lived or long lived? If you watch the action in your heap with VisualGC/Visual VM, and in the display you see everything get cleaned up in the eden & survivor spaces with each GC, then you probably have mostly short lived objects.
    You may also see that your survivor spaces are too small. If too small, objects get promoted to the old generation space too quickly, filling up your old gen space unnecessarily, and creating long GC pauses.
    The best situation is where eden and the survivior spaces are sized such that as many as possible objects get cleaned up on an ongoing basis without them moving to the old generation space as they age.

    What do you see if you use the least number of options you need to start the application. I would try just
    -mx1024M -XX:MaxPermSize=512M I would only add options which appear to improve performance.

  • Advice on Apple TV Pausing During Streaming (Apple Remote App too)

    With all the talk and excitement of the new Apple TV, I'm not sure if this problem applies. I'm not sure if the new Apple TV streams movies like the old one did.
    Regardless, I have had some difficulty with my 40GB Apple TV that I finally figured out after months. I'll describe my network, describe the problem and solution, and why that solution works.
    1. My network.
    I have:
    an iMac connected wirelessly to an Airport Extreme
    a Western Digital hard drive connected via ethernet to my Extreme. My movie library is here
    an newer airport express (N) connected to my stereo on the main floor
    an older airport express (G) connected in the basement with my XBOX connected to it via ethernet
    an Apple TV in the basement.
    2. The problem
    When I'm streaming movies, it often works just fine. However, sometimes, during a movie, the playback pauses as if Apple TV needs to re-cache the movie or something. It will pause for about 10 seconds or so then keep playing. When it starts to play again, the movie jumps forward the 10 seconds to the current playing point. This then works for anywhere from another 30 seconds to several minutes. When this pausing occurs, if you click the Apple remote to bring up the status bar, you can see the timeline of the movie continue to move along. Then, other times, the whole thing will somehow cure itself and start working again.
    Unrelated but later found to be related problem with Apple remote on iPod touch
    Sometimes, trying to connect to my iTunes library, it couldn't connect and I'd get the message that my firewall is getting in the way. You'll see as it turns out, this isn't the problem.
    How I found the solution
    When this pausing occured, I would unplug the Airport Express in the basement. This is the one the XBOX is connected to. After a couple of seconds, I'd plug it back in. On the TV screen, it would revert back to the movie list and show that there were no movies to play. Then, after a couple of seconds, my movie list would reappear. I'd restart my movie and it would work just fine.
    Here's what was happening
    Somehow, I configured my Airport Express router in the basement to be an extention of the network The problem is that the Express in the basement was G speed and not N speed (I think that was the problem). Sometimes, Apple TV would connect to the Express router in the basement rather than my Airport Extreme router upstairs. When this happened, the pausing during streaming would occur. This also makes sense now that the movie list would briefly disappear when I'd unplug my Airport Express in the basement. The connection would be lost but then a few seconds later, Apple TV would find Airport Extreme and reconnect. Then it would work perfectly.
    I also noticed two separate networks coming up when I did a network scan. I would fire up my WIndows laptop and do a network search. I would get two separate instances of 'Mynet'. One would be N speed and the other would be G speed. This now also makes sense since one of them was my Express and the other was my Extreme.
    The solution
    I did two things. I swapped the two Express routers so I had the N speed router in the basement connected to the XBOX. I also configured the network so it was 'all the same network'. Now, when I do a network scan on my Windows laptop, I no longer get the two separate instances of 'Mynet' coming up.
    Since then, I have never had a problem streaming movies nor have I had a problem with my Apple Remote app on my iPod Touch.

    I'm having similar problem.
    My set up:
    iTunes running on my MacBook C2D, 2GB RAM
    Movie contents are in an external USB2.0 HDD (7200rpm) attached to Airport Extreme (802.11n)
    Typical movie content is mp4 file with 1.8mbps bitrate.
    When my MB is completely idling state, ATV gets data w/o pausing.
    When MB is doing some task (web browsing, etc), no problem.
    When iTunes starts downloading some video podcasts (to MB, not syncing to ATV).... the movie streamed to ATV gets paused and gets into the same state as gjbonnington described.
    Any idea how to solve??
