Garbage Collection Pauses in a client application: Trashing.

Hi,
we have put in production a financial trading application written in Java. We are experimenting a strange behaviour of the garbage collector. We are experimenting GC pauses every 4-5 hours which raise CPU time to 100% for 30 seconds. These pauses are not-deterministic. Memory consumption of the entire application is very low (about 30MB).
This is a strange beheaviour we have detected in the log file of GC:
5020.027: [GC 27847K->14659K(63936K), 0.0086360 secs]
5020.036: [Inc GC 14659K->24546K(63936K), 0.0149416 secs]
5020.107: [GC 27842K->14658K(63936K), 0.0086947 secs]
5020.116: [Inc GC 14658K->24546K(63936K), 0.0094716 secs]
5020.181: [GC 27842K->14658K(63936K), 0.0086846 secs]
5020.190: [Inc GC 14658K->24546K(63936K), 0.0095778 secs]
5020.255: [GC 27842K->14658K(63936K), 0.0102155 secs]
5020.266: [Inc GC 14658K->24546K(63936K), 0.0084659 secs]
5020.335: [GC 27842K->14658K(63936K), 0.0088606 secs]
5020.344: [Inc GC 14658K->24554K(63936K), 0.0084514 secs]
as you can see in one second the GC and the IncGC are called many times. WHY?
We have read articles and tried all various known settings. But we didn't find any solution and at the moment we don't know how to move.
Thank you for your hint
Piero

Which settings have you tried? By the looks of things you've not set any of your JVM memory variables.
Try bumping up your maximum heap space using -Xmx.
If you are running on a nice server try using -Xmx256m -Xmx256m -Xmn64m, these should help for a start.
Also why are you using the "incremental garbage collector" when you have such a tiny application as you can see a full garbage collection is only taking 0.01 seconds.
Also try reading this http://java.sun.com/docs/hotspot/gc/

  • Simulate full garbage collection pauses

    Hi,
    I'm doing some performance tuning for our Java systems, and one thing I want to test is how the applications behave when "stop-the-world" Full GC pauses of various different durations occur in our JVMs. We have seen some problems in our systems where longer GC pauses have negative effects. However, it is difficult to recreate these conditions using the applications themselves. Does anyone know if it is possible to force a JVM to do a "stop-the-world" pause of a specified duration, that would simulate a GC?
    Notes -
    1) I'm not talking about forcing a GC - I know how to do this but this give no control on the duration of the GC. Appreciate might be able to work a solution by writing a program to use up X amount of memory followed by a forced GC, but hoping for something simpler!
    2) We have already exhaustively tuned our JVMs to reduces frequency and duration of Full GC as much as possible but they do still need to occur occassionally. Have engaged with forums alredy on how best to do this, so no need for more info on this!
    3) We are using multiple JVMs which communicate with each other (RMI, etc.), and a large part of what I'm testing is the effect on JVM A of a long GC pause in JVM B while A is communicating with B
    4) JVM version is 1.5.0_u18, normally running on Solaris 9/10
    Thanks in advance for any insights!

    Adrian

    Hi,
    The docs here:
    [http://docs.sun.com/app/docs/doc/806-1367/6jalj6mv1?a=view|http://docs.sun.com/app/docs/doc/806-1367/6jalj6mv1?a=view]
    seem to suggest something like what I want to do could have been achieved in Java 1.2, by sending SIGQUIT to the process. However, in Java 5, SIGQUIT just creates a thread dump. Anyone know if its possible to achive the behaviour from that link in Java 5 by any other means / signal?

  • Garbage collection pauses screw up my cluster.  JVM tuning suggestions?

    I am running Sun's 64 bit JVM 1.7.0. Everything hums along nicely until my storage enabled nodes all show GC log entries like these and then the cluster experiences timeouts. This happens like once a day at most. Suggestions? Thinking maybe add more storage enabled JVMs? Any JVM settings I should use to prevent this? What can determine the cause? I don't think the machine's CPU is maxed out at the time.
    Thanks,
    Andrew

    Today i used
    -XX:+UseConcMarkSweepGC
    -XX:+UseParNewGC
    -XX:-CMSConcurrentMTEnabled
    -XX:+CMSScavengeBeforeRemark
    and had the same problem with all 3 storage enabled nodes simultaneously when I closed the Extend app. The GC logs from those storage nodes were nearly identical with each showing three "abort preclean" messages like below before eventually stabilizing again. CPU usage for the storage node JVMs was up a bit on the machine at the time then eventually came down. Extend proxy node CPU usage never goes up very high and GC times are always good there.
    Could it be because the Extend app has many CQCs running and when the app disconnects without shutting them down properly their results queue up in the storage enabled nodes? Something the Extend proxy can't pass along is getting added to old space?

  • Aggressive Heap and garbage collection in 1.4.2

    We are trying to monitor the memory usage and the garbage collection for one of our application servers. We are using JDK 1.4.2 b-19 on solaris 8. The machine has 4 900 Mhz CPUs and 8GB ram. The VM options are:
    -server -XX:+AggressiveHeap -Xms3512m -Xmx3512m -verbose:gc
    -XX:+PrintHeapAtGC -XX:+PrintTenuringDistribution -XX:+PrintGCTimestamps.The first full GC kicks in when the old generation gets full which is understandable. After that however, the full gc kicks in much more frequently and even the gc pauses are fairly long. Below are some of the output from gc.
    For the first GC the old generation was almost full.
    PSYoungGen total 1379840K, used 1324288K
    PSOldGen total 2123648K, used 2103378K
    For the second GC, young generation is 25MB out of 1300MB and old generation is 1100MB out of 2100MB. Still the full gc kicked in and took 23 secs.
    PSYoungGen total 1356608K, used 25856K
    PSOldGen total 2123648K, used 1169626K
    I understand that the adaptive sizing is kicking in (by default) but it should make life better not worse. If the full GC could wait till the old generation gets full again, I will get lesser number of full gc pauses and few and far in between.
    Any idea as to what I can do?
    thanks

    We also had similar issues...If you are using RMI it might cause Full GC. This is the snippet from http://java.sun.com/docs/hotspot/gc/
    <snip>
    Garbage can't be collected in these distributed applications without occasional local collection, so RMI forces periodic full collection. The frequency of these collections can be controlled with properties. For example,
    java -Dsun.rmi.dgc.client.gcInterval=3600000
    -Dsun.rmi.dgc.server.gcInterval=3600000
    </snip>
    By default this is 1 min. So try changing this and try it out.

  • Exorbitant Garbage Collection Times

    Once a day, at around 4-4:30am, our application experiences a single Full GC with taking an exorbitant amount of time. A Full GC kicks in and pauses all threads for 5 to 30 minutes. Full GC's regularly occur at other times and complete in 5-20 seconds. Anyone seen this or any have any ideas about this?
    Example of normal GC that occurs frequently throughout the day:
    [Full GC[Unloading class $Proxy136]
    4632722K->1616289K(6141952K), 14.9400110 secs]
    Example of ridiculously long GC that occurs daily at 4-4:30am:
    [Full GC[Unloading class sun.reflect.GeneratedSerializationConstructorAccessor455]
    5456231K->2017269K(6141952K), 492.0402160 secs]
    Here's our VM params:
    -server -XX:-OmitStackTraceInFastThrow -Xincgc -XX:+CMSIncrementalMode -XX:+CMSIncrementalPacing -XX:MaxGCPauseMillis=20000 -XX:+DisableExplicitGC -XX:NewSize=1500m -XX:SurvivorRatio=18 -verbose:gc
    -Xms6000M -Xmx6000M
    We're running Java 1.6 on Linux, Redhat 3.

    Just experienced a 498 second (yikes!) garbage collection pause. The entry from the log is below (we added -XX:+PrintGCTimeStamps -XX:+PrintGCDetails and removed -verbose:gc). I will also send the entire log to the email address you have provided.
    Note that we actually reduced our Xmx to 4000M (from 6000M) despite this machine having 8gig physical ram in the hopes that this would prevent any paging, and it seems to have drastically improved the situation - these exorbitant pauses now occur only very seldomly.

    You can see that between 12:48am and 9:38am, the Server is pausing for a combined total of TWELVE MINUTES! Often for 2 whole minutes at a time, during which the Server is completely unresponsive.
    I have read Sun's GC tuning guide at http://java.sun.com/docs/hotspot/gc/index.html but it is not much help:
    It says "Pauses can be minimized by using a small young generation and incremental collection, at the expense of throughput."
    Well, I AM using incremental collection, and the young generation is the default size, which is quite small I believe. (32 MB max?)
    It also says "Unless you have problems with pauses, try granting as much memory as possible to the JVM. The default size (64MB) is often too small."
    Well I DO have problems with pauses, but I HAVE to allocate a ton of memory. The Server must support hundreds of simultaneous users, each with hundreds of K's of personal, dynamic, temporary data.
    It also says "Unless you find problems with excessive major collection or pause times, grant plenty of memory to the young generation. The default MaxNewSize (32MB) is generally too small."
    I AM having problems with excessive major collections and pause times, so according to this I should NOT grant more memory to young generation (eden).
    What am I left with? Nothing! I am totally out to lunch here. The box this is running on is a dual P3-600 with a gig of RAM and Red Hat 6.2, with Sun JRE 1.3.1_02. My startup command line options are:
    java -server -Xincgc -verbose:gc -Xms256M -Xmx900M
    What should I do? The Tuning guide essentially says to screw around with generation sizes, but none of its specific tips seem to apply to me! This is a production server and I am worried about making things worse by playing around, so I was hoping someone out there might have some experience with this and concrete advice before I just start messing around with the memory map. Should I increase the young generation size? Decrease it? Something else altogether? HELP!

    With default settings, I am getting horrible performance, under peak load, 25%-50% of server time is being spent with GC, approx. 11,000 minor GCs per hour! And a Full GC every hour or two which takes up several minutes. On average, I am losing 13.09 minutes per hour due to minor GC, and 54.5 seconds to major GC.
    I tried your settings, Chuck, and they seemed to be working beautifully at first... minor GCs were now occuring once every few minutes for a couple seconds, instead of 3 times per second for a tenth of a second. Minor GC were now taking 1.06 minutes per hour instead of 13.09, more than a 1300% improvement!
    HOWEVER...
    After 7 hours, the Server started getting REALLY slow for no apparent reason. It seemed almost as if reading from sockets was suddenly becoming extremely time intensive. Then I got a HUGE minor GC that took 25.6 seconds. [GC 507410K->478034K(551296K), 25.6328459 secs], then a couple minutes later, the Server CRASHED with this output:

    Yummy. Signal 11's really make my day fun :(. I tried restarting the Server, but it crashed again in the same way 15 minutes later. Then I switched back to default settings and it has run fine all weekend.
    The Sig11 makes me think either our C lib is buggy (our Linux distro is getting a bit old), or we have a physical memory problem. Odd that it only shows up when I tried your new settings though...

  • SystemManager and Garbage Collection

    Hi everyone, I have a question regarding the SystemManager and Garbage Collection. I have and application that loads in its assets via a swc created in Flash. In that swc I have different MovieClips that act as the different screens of my application each one being tied to its own custom class. For example one MovieClip is a login screen another is the main menu etc. These screens contain components, text fields and animations. The problem that I am having is when I move from one screen to the other the garbage collector is not cleaning up everything. There are still references to the MovieClips that have animations for example. So even though I remove the screen via removeChild and set the variable reference to that object to null it is not releasing the MovieClips. When I pull it up in the profiler it shows me that SystemManager is holding references to them. Also if I debug the applicaion and look inside the instance of the MovieClip I can see that the private property "listeners" has values, but I am not adding listeners. It appears that the SystemManager is adding listeners. Does anyone know how I can clear these listeners or force the SystemManager to release these items. Any ideas or help would be greatly appreciated. I am fairly new to dealing with memory management and garbage collection in Flex. I am using Flash CS4 to create the swc and Flash Builder 4 Beta with the 3.4 framework and Flash Player 10 to create the app. If you need me to clarify any of this please let me know. Again any help or ideas on where to go from here would be great!

    This chain says that the focusManager is referencing UserMenu.  Is there a default button or focusable objects in UserMenu and references from UserMenu to the objects in question?
    BTW, the CS4 fl.managers.FocusManager and any fl.. classes are incompatible with Flex, so make sure you're not using them in your MovieClips.

  • Low Latency Garbage Collection

    Hi,
    What is the best garbage collector configuration for a low latency system?
    Multi-threaded server process running on a multi-core box (say 8 cores). Reading and writing messages to the network, no disk. Want all messages to be processed in as timely a manner as possible wrt their individual latencies. Want to avoid some messages being delayed by a garbage collection pause. What will give me the 'fairest' latency time amongst the messages?
    I should add, Java SE 1.6 recent version.
    Thanks in advance for you suggestions.

    The simplest approach is don't create any objects in your critical path. (Or keep them to a minimum) Javolution and Joda-time have a libraries which helps.
    You can try the concurrent mark sweep or G1 collectors to see if they help.
    You can get the GC low enough that you will see other delays such as the SMC or network jitter or memory bank effects instead.
    i.e. If your server is simple enough, you can see more jitter from the hardware/OS than Java itself.

  • 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.

    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.

  • Word opening in Client Application in SharePoint document library when feature is not activated in manage features in site collection

    Hello, I wish for all Word documents to open in the browser for my SharePoint document library on my team site.
    The feature 'open in client application' is not activated in Features for the site collection and the setting in the document library is set on 'Use the server default (open in the browser)
    When I select File > new> from the ribbon in the document library - it still opens Word in the client application?
    Any ideas on this?
    Is there a general Office 365 setting over riding SharePoint somewhere?
    Regards
    kegan1

    Okie don't open up a ticket. Can you please open internet explorer...See if its the latest version. Once you have done that can you login to the SharePoint site. Then go to the internet wheel option  in top right corner > select manage add on >
    Click on toolbars and extensions on left > then click on SharePoint open documents in client and disable it. Close the browser completely now for the changes to take effect. Open internet explorer once again and then try to go to site collection click on
    file and create new. The word will open up in browser now. This has to be done on each and every machine in your firm so that users will be able to open up only in browser. Out of the box there is only one way is to customize the ribbon and remove the new
    option from there or creating an all together new ribbon for your SharePoint from visual studio.

  • Howto Force Garbage Collection manually in Oracle Application Server

    Hi,
    I have a Oracle SOA suite installed on Oracle 10g Application Server. The heap memory for the SOA oc4j container is 2G with a permgen space of 256M. But it looks like there is some memory leak somewhere and the Heap area is getting filled frequently and this causes an *[libopmnoc4j] OC4J ping attempt timed out* and as a result of this the SOA oc4j container gets restarted automatically.
    Is there any means by which we can force a Garbage Collection manually so that this automatic restart does not happen.
    Kindly let me know if it is possible to trigger a Garbage Collection manually in Oracle Application Server.
    Thanks,
    Vijay.

    We had a similar situation where the oc4j instance will throw OutOfMemoryException and opmn will restart a new instance every 10-12 hours. The JDBC 10.2.0.3 driver has a memory leak in the XA Resource classes. There is a fix available in metalink.

  • Use Garbage Collection Liberary  in C++ application

    I knew that Garbage Collection liberary was implemented using C++
    Can I use it when I write C++ application to avoid any memory leak happens in my application.

    You probably need to reinstall OS X, but try this first.
    Please read this whole message before doing anything.
    This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
    Step 1
    The purpose of this step is to determine whether the problem is localized to your user account.
    Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
    While logged in as Guest, you won’t have access to any of your personal files or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
    Test while logged in as Guest. Same problem?
    After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
    *Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
    Step 2
    The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, or by a peripheral device.
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.  The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    Test while in safe mode. Same problem?
    After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of steps 1 and 2.

    Ok, itunes keeps crashing. Have used disk utility to repair permissions, in regular mode, safe mode, and at start up. None of that worked. Was thinking maybe internet recovery may be my only option.
    Here is the crash report, not sure how much i should post, so i will give the whole thing

    Hi there rapitupnow9!
    I have a couple of links here for you that should be able to help you with this issue. First, I would suggest isolating the issue by following the steps located in this article:
    Isolating an issue by using another user account
    http://support.apple.com/kb/TS4053
    If you are still having trouble with iTunes in the new user account, then you should attempt to reinstall iTunes on your computer. Information about doing this can be found here:
    OS X Lion: Reinstall applications that came with your computer
    http://support.apple.com/kb/PH4360
    Thanks for using the Apple Support Communities!
    Cheers,
    Braden
