Memory leak in xerces on Solaris platform

We are seeing memory leaks with xerces 2.5.0 on the Solaris platform. Has anyone encountered a similar problem and is there a fix for it.

I have seen other apps sucessfully running in AppStore. Is there something which I am missing ??????. Help me with the issue Guys.......... it's putting  me out of businness.

    We suspect it to be a memory leak issue. Are there memory leak debugging tools for sol10.
    we were unable to use dbx as we got the following error.
    (dbx) check -memuse
    dbx: Incompatible libthread.so/libthread_db.so found. Error checking disabled
    See `help rtc mt' for details.
    Also dbx's 'check -access' option is not supported for X86.
    Waiting eagerly for any support/guidance.
    Thanks in advance.

    I had the same problem on Solaris 10 sparc. The problem seems to relate to symbolic links with
    long names not being extracted correctly from the tar file (resulting in @LongLink files popping
    up around the place). If you use the .zip source file then the build goes fine.

  • Memory leak using pthreads on Solaris 7

    I'm on Solaris 7
    uname -a:
    SunOS zelda 5.7 Generic_106541-18 sun4u sparc SUNW,Ultra-250
    compiling with g++ (2.95.2)
    purify 5.2
    I consistently get memory leaks related (apparently)
    to the pthreads lib. I've set the error reporting chain length to 30 (way big), the start of the chain in every case starts with threadstart [ libthread.so.1 ]
    when I end my process, I Join the threads before deleting them. What else can I do to get rid of these leaks?
    thanks,

    is it worth upgrading to a 64 bit OS with more ram.
    Well you're talking a fairly hefty investment in fact your best bets buying a new machine at that point since the motherboard would need to be upgraded as well as memory and OS.
    Now  I run on a 64 bit OS 12 gigs of ram, but i love my plug-ins, and most are 32 bit, so you would still be using the 32 bit Photoshop if you want the majority of all plugins for photoshop to work. Well while the 32 bit version still have the memory limitations on how much memory it can use, Because its in the 64 bit OS, you have available the full amount of that limitation available to the application.
    I can run several different memory intensive applications at one time and normally not have an issue.  I say normally cause, sometimes i will crash my graphics driver if i open one too many 3d apps hooked into the Nvidia drivers.
    I normally only reboot maybe once a week.
    So in short, would it help you to be able to go 64 bit with more ram, Most Certainly even more so if you could care less about plug-ins and want to use the 64 bit version. should you go to 16 gigs of ram.. That depends on your budget really,
    Personally I always plan to upgrade when I build my systems, Putting in the largest chips you can with out filling all the slots leaving room for upgrading if needed. that way you're not filling all your slots with cheaper lower memory ram that you would have to replace them all to upgrade.
    Hope this helps a bit

  • Detecting a memory leak in a process running on Solaris 5.7

    Hi,
    Iam running my application on solaris 5.7 platform.
    I can see clear memory leak in that process.
    Is there any tool or in-built functionality on solaris 5.7 to detect/fix that leak.
    Thanks in advance,
    Avvaru

    Thanks for the reply. I already turned it off in both Safari and Spotlight preferences. However the problem persists. The process still runs, and from time to time it decides to leak all the memory as well. I really can't understand what the reason might be.
    To be clear, in Safari-->Preferences-->Search-->Smart search field-->"Include Spotlight Suggestions" is un-checked. In Spotlight preferences all three "Spotlight Suggestions", "Bookmarks & History" and "Bing Web Searches" are un-checked. Process still runs under Spotlight as can be seen here:
    After the last post I let it run for a while when it happened again, and below is just before i terminated it. Look at the memory usage!

  • Memory leak in WLS6.1 sp3 on Solaris?

    We are running WLS 6.1 sp3 on Solaris 8 using Sun's 1.3.1 JVM with BEA's
    JDriver to connect to Oracle (8.1.7). We have set the JVM to a maximum heap
    of 512M (-Xms256m -Xmx512m).
    The issue is that we are now seeing (via pmap) the resident memory growing
    to ~1GB. Yet, the WLS management console is reporting memory usage of ~200M.
    So, if we are to believe WLS, then the JVM (or some native library) is
    chewing up the extra memory.
    Having examined the results of "pmap -x <pid>", I see the heap (and some
    anon) mem/file are quite large.

    Questions:

    - Should it be possible for pmap's value of "heap" to grow larger than the
    "Xms" setting? We have observed this recently, but the numbers above don't
    reflect this.
    - Any idea what the "anon" is or how to determine what it is?
    - Do you know of any tools that might help me determine what is using that
    memory or what is in it?
    Any suggestions will be greatly appreciated...
    Thanks in advance,
    Erik

    If you set -Xmx512m then the java heap will grow no larger than 512MB.
    WLS is reporting the size of the java heap. (It is a java program after
    all and doesn't know a lot about what native code might be doing.)
    My first thought is try running with Oracle's thin (type-4) driver.
    Since this is java code, it will use the java heap. If the memory usage
    drastically changes, then you can point the finger at the jDriver.
    Are you using any other native code / libraries?

  • Memory leak in solaris 9

    Hi ,
    I have Oracle9i database running on Solaris 9. After every 6 days my solaris box went out of space although its a test box and there is no activity on the system. Why the hell it takes all the ram and swap space when there is no activity on the system except Oracle Instance is running with no user connection. What process are running in the background that takes all the memory and i have to restart this box every week. IS THERE ANT PATCH OF MEMORY LEAK FOR SOLARIS9?. I am not a solaris administrator and i have to fix this problem before moving my system to production. I would really appreciate your help.
    Thanks.

    Hi ,
    I have Oracle9i database running on Solaris 9. AfterI have had for some months been running oracle 9i (and 8i) under solaris 9. There have been no problems and the server has been stable.
    It sounds like you may have misconfigured the solaris kernel. It also sounds like your SGA is too large to fit in memory.
    So I guess the first step would be to check the SGA and then the /etc/system file.
    Here is what mine looks like for example:
    SQL> show sga
    Total System Global Area 219644872 bytes
    Fixed Size 730056 bytes
    Variable Size 167772160 bytes
    Database Buffers 50331648 bytes
    Redo Buffers 811008 bytes
    SQL>
    bash-2.05$ tail /etc/system
    set shmsys:shminfo_shmmax=4294967296
    set shmsys:shminfo_shmmin=1
    set shmsys:shminfo_shmmni=100

    set semsys:seminfo_semmsl=256
    set semsys:seminfo_semmns=1024
    set semsys:seminfo_semopm=100
    set semsys:seminfo_semvmx=32767

    You need to gather more system information to help you troubleshoot.

  • Process memory leak issue  solaris 10

    I have a process which has a memory leak issue. I ran this process on solaris 9 as well as solaris 10. When i run prstat command i get a different output for two. Funny thing is that memory leak noted in solaris 10 is much more than that in solaris 9 e.g if it is 1 MB in solaris 9 then its 4 MB in solaris 10.
    What can be possibly causing this ? Is this related to kernel implementation on diff solaris ?

  • Memory Leak in 8.1.6.0.1 JDBC/OCI for Solaris

    Hello,
    there is a memory leak in the 8.1.6.0.1 JDBC-OCI driver for solaris.
    The leak causes your jvm to eat up all memory
    if you reuse callable statements
    (calling one statement multiple times with
    different values).
    The thin driver has no such problem. Is
    there any fix available ?

    Ok. The code spans multiple classes and
    most of it comes from a customized version
    of the Enhydra Java Application server.
    I have a class called "StandardDBConnection"
    which caches CallableStatements and is a
    wrapperclass for java.sql.DBConnection. The
    interesting method here is "prepareCall":
    * Get a callable statement given an SQL string. If the statement is
    * cached, return that statement, otherwise prepare and save in the
    * cache.
    * @param sql The SQL statement to be called.
    * @return a new CallableStatement object containing the
    * pre-compiled SQL statement.
    * @exception java.sql.SQLException If a database access error occurs
    * statement.
    public synchronized CallableStatement prepareCall(String sql)
    throws SQLException {
    PreparedStatement preparedStmt;
    logDebug ("Prepare call: " + sql);
    validate();
    preparedStmt = (PreparedStatement)preparedStmtCache.get(sql);
    // Check if the object returned by the cache really is a
    // callable statement. if it is not, someone did call first
    // prepareStatement() and now prepareCall() with the same
    // sql. Silently replace the existing cache entry by a
    // callable statement in this case.
    if (preparedStmt instanceof CallableStatement) {
    preparedStmt.clearParameters();
    else {
    // Need to close the old PreparedStatement in case we have to
    // replace it with a CallableStatement
    if (preparedStmt != null) {
    preparedStmt.close();
    else if (preparedStmtCache.size() >= maxPreparedStmts) {
    String key = (String)preparedStmtCache.keys().nextElement();
    ((PreparedStatement) preparedStmtCache.remove(key)).close();
    preparedStmt = connection.prepareCall(sql);
    preparedStmtCache.put(sql, preparedStmt);
    return (CallableStatement)preparedStmt;
    The statements get closed when I close the
    connection:
    boolean closeStmts = true;
    // Close the prepared statements.
    Enumeration e = preparedStmtCache.keys();
    while (e.hasMoreElements() && closeStmts) {
    String key = (String)e.nextElement();
    try {
    ((PreparedStatement)
    preparedStmtCache.remove(key)).close();
    } catch (SQLException except) {
    // Ignore errors, we maybe handling one.
    closeStmts = false;
    log.write(Logger.NOTICE,
    "DBConnection[" + id + "]: " + url +
    "\nUnable to close statements. Continuing....\n");
    In my classes using database queries I just
    use the prepareCall method of DBConnection
    and do not have to care about anything.
    Works perfectly with the thin driver, but
    as soon as I switch to oci... :-|

  • Memory Leak with 4.5.1/Java/Solaris

    Hi,
    We are currently running a Java Application using RMI/Weblogic 4.5.1/Solaris 5.7/Java 1.22.
    Behavior that has been observered during the day is that memory usage reaches a stage in which it begins increasing and GC doesn't recover any memory, until the heap reaches an extremly large size, then recovers a significant amount of memory.
    We have even seen the java process grab more memory than specified in the -Xmx parameter and experience a java.lang.OutOfMemory error.
    I have seen postings that describe similar issues in this newsgroup, but none that define a solution.
    This problem is intermittent, and our application can run an entire day without experiencing this memory leak. On the other hand there are days when the memory leak occurrs even when the system is idle overnight.
    Please let me know any information you have gathered on this subject.
    Regards,
    Mark Evans

    try increasing your virtual memory on your NT system...

    Hi,
    I observed the same confusing stuff in my tests. But I run weblogic 4.5.1 on Windows NT with JDK 1.2.2-w
    Usually, I would get a "Low virtual memory" message from windows
    and if I click ok & shuffle thourgh my windows I would be ok.
    But since last 2 days, I would keep the server running overnight.
    When I return in morning,
    I would find a "Low virtual memory" message and
    on clicking OK. I would find another message tell me that java.exe (which was running weblogic) crashed!!
    Now today I tried to watch the memory usage in Task Manager. And I found the most wierd thing.
    I saw that even when the system was doing virtually nothing,
    except print a string at intervals, the memory usage would go
    up steadyly.
    Even doing a forced finalization and gc did not seem to stop it.
    BUT, BY CHANCE I HAPPEN TO MINIMISE AND MAXIMISE THE WEBLOGIC
    CONSOLE OUTPUT WINDOW.
    WHAT I SAW IN THE TASK MANAGER AMAZED ME!
    THE MEMORY USAGE IN TASK MANAGER HAD GONE DOWN TO 24XXKB, WHILE
    IT WAS ABOUT 20000K OR EVEN MORE.
    This seems to support the fact that during my test, I would
    get the "low virtual memory" message and if OKed it and shuffled
    though application windows (maybe minimise, maximise the weblogic
    console output window in process), I would be able to complete
    my application. But when the message appears during night runs,
    nothing is done and by morning, when I reach to work,
    I would see that weblogic had crashed!!
    You may try that and see if it helps you.

  • Memory leak using 10.2.0.3 OCCI client on Solaris 10

    Hi,
    We are using OCCI client libraries to connect our C++ program to the Oracle Database. The program does a lot of selects, inserts and SP calls.
    Oracle client and Oracle server both are 10.2.0.3 on Solaris 10.
    We have been observing a memory leak of 4M bytes in the C++ program every few minutes since last few days. On debugging through Purify, libumem, and Sun Studio 12, we finally managed to narrow down the problem to the Oracle client library OCI calls.
    The Sun Studio leak check shows the following -
    Leak #37, Instances = 157, Bytes Leaked = 655004

    On searching Metalink and various other forums, I found similar issues faced in 10.2.0.1.
    Could someone advise if there are any bugs corresponding to this which have been closed. Would upgrading to 10.2.0.4 solve the problem?

Please Help.If you have written the JNI, the JNI itself (java calls, methods, etc) to be OS agnostic then it shouldn't matter. In that case you check the windows code (not jni), the linux code (not jni) and the jni code itself independent of each other.
    If you haven't made the JNI OS agnostic the question would be why not?

  • Memory leak in Solaris - SunOS 5.7, jre1.3.1

    Hi,
    I hava a java application that spawns about 100 threads. Each thread sends a request to WebLogic server 6.1. We are using Oracle 8.1.7. They are all running in a Sun box, 2 CPUs and 6gig memory.
    JRE = 1.3.1
    SunOS = 5.7
    Weblogic = 6.1
    Oracle = 8.1.7
    (All running on the same box)
    When we start the client application, running top shows that ,
    the client JVM process - uses 40 MB of memory
    WebLogic - uses 250 MB of memory
    But the available memory comes down drastically (almost by 350 MB), and on bringing both the client and weblogic down, we are not able to get this 350 MB back
    Running JProbe, doen not show any memory leak in our application
    we are using the hotspot client version
    -Xms = 128m
    -Xmx = 128m
    Any help is appreciated

    It looks like i am also facing the same problem with my application . If by some chance you were able to solve this problem do send a mail to [email protected] I just posted the question. while searching the web i found your question which looks similar but not answered. Hope you could give me some input

    A select is executed, a resultset is fetched and the resultset is immeidately closed. The same piece of code has been running at various production systems without any problems. Most of the other sites are either 10.2.0.4 or 9i.
    On searching Metalink and various other forums, I found similar issues faced in 10.2.0.1.
    Could someone advise if there are any bugs corresponding to this which have been closed. Would upgrading to 10.2.0.4 solve the problem?
    Thanks.

    Hi,
    Apparently a similar issue is being discussed over here:

  • Sun Application Server Platform Edition 8.2 Memory Leak!!

    Hi there,
    I've been testing a benchmark tool and been used App Server with Adventure Builder deployed as my SUT.
    What happens is that I've found that the server crashes within few minutes with a memory leak problem. I was testing a version that has already set a timeout to the file descriptors and it stayed up and running for some hours, but we can observe the memory decreasing too.
    I've used the netbeans profiling with a "no-alterations" App Server and it crashes after 20 minutes or so.
    I've associated the increase of memory (about minute 4) with the creation of threads called iMQReadChannel that kept running until the server crashes.
    Can you help me with that?
    Is there a bug fix for this?
    By the way, can anybody tell me some applications based in web services that I could use as a SUT? it could be some BPEL examples..
    Thanks in advance

    What exactly are the symptoms of the crash? If it's actually a crash and a core dump, then if you can provide more details on that (hs_err_pid file and any associated messages), we can file a bug against the JVM. If you get memory exceptions, what specifically do they say?
    Also, which JVM are you actually using? There are some known bugs with JDK 1.5.0_06 and earlier around memory and file descriptor usage; we recommend that you use JDK 1.5.0_09 or a JDK 6.0 beta. For that matter, you will see better performance in general with version 9.0 of the appserver

  • Pro*c multithreaded application has memory leak

    Hi there,
    I posted this message a week ago in OCI section, nobody answer me.
    I am really curious if my application has a bug or the pro*c has a bug.
    Anyone can compile the sample code and test it easily.
    I made multithreaded application which queries dynamic SQL, it works.
    But the memory leaks when i query the SQL statement.
    The more memory leaks, the more i query the SQL statement, even same SQL
    statement.
    I check it with top, shell command.
    My machine is SUN E450, Solaris 8. Oracle 9.2.0.1
    Compiler : gcc (GCC) 3.2.2
    I changed source code which is from
    $(ORACLE_HOME)/precomp/demo/proc/sample10.pc
    the sample10 doesn't need to be multithreaded. But i think it has to work
    correctly if i changed it to multithreaded application.
    the make file and source code will be placed below.
    I have to figure out the problem.
    Please help

    Sample Program 10: Dynamic SQL Method 4
    This program connects you to ORACLE using your username and
    password, then prompts you for a SQL statement. You can enter
    any legal SQL statement. Use regular SQL syntax, not embedded SQL.
    Your statement will be processed. If it is a query, the rows
    fetched are displayed.
    You can enter multi-line statements. The limit is 1023 characters.
    This sample program only processes up to MAX_ITEMS bind variables and
    MAX_ITEMS select-list items. MAX_ITEMS is #defined to be 40.

    sqlnul() is used to reset the high-order bit of
    the datatype and to check whether the column
    is NOT NULL.
    CHAR datatypes have length, but zero precision and
    scale. The length is defined at CREATE time.
    NUMBER datatypes have precision and scale only if
    defined at CREATE time. If the column
    definition was just NUMBER, the precision
    and scale are zero, and you must allocate
    the required maximum length.
    DATE datatypes return a length of 7 if the default
    format is used. This should be increased to
    9 to store the actual date character string.
    If you use the TO_CHAR function, the maximum
    length could be 75, but will probably be less
    (you can see the effects of this in SQL*Plus).
    ROWID datatype always returns a fixed length of 18 if
    coerced to CHAR.
