To many open files

Hi gurus i have a problem on ssl ldap and and and the file descriptors:
OS: SunSolaris 8
Version 1.4.2
ID JDK
Build Level 1.4.2_04-b05
Build Date 06/27/2004
the strange problem is related on too many open files and file descriptors
when a first user login and logoff no related broblems on the /WEB-INF/cacerts files but when a second user login and log off
the files remains open and the output log give the i too many open files the log

what is the cause?
thank you
AP

sorry i can explain well the issue
for our experience
LDAP access causes the opening a lot of file descriptor?
The LDAP proves ist still running and is still opening files. Meanwhile, because of the SSL communication with application, some files are Created in the CACERTS directory
Suddenly, the OS has reached its file descriptor limit: an error message �Too many open files� appears
Question: the situation is : that files cannot be closed in the CACERT director, because the OS has not more file descriptors (because the ldap process has used all file descriptors to the limit)?
is related on LDAP this problem?
thank you for your kindness guys!

    But this problem is understandable, as the database is not running. The main problem why database is not running, I have found the reason but do not understand how to solve the problem.
    Since, the database was not running, I tried to startup the database, I then came across the following which is my problem (Why so many files are open? Linux OS error says too many files open. See below,

    Hi,
    yes, this DB was functioning o.k. this configuration script was part of RMAN daily backup.
    Last night the backup failed. So, when I opened "Failed job" in the EM, I saw this type of messages.
    That was the starting point. Gradually, I tried to narrow down on to the actual problem and found the findings as I have posted.
    One way of sovling problem, I thought that, all these processes I would kill and then try to open the database, it might startup. However, that wouldnot lead me in ensuring this won't occur again.
    That's why I am trying to understand why it should open, so many processes (why spawn so many .flb files?) Any thoughts you have around this?
    I will try to restart the OS as the last resort.
    Thanks for your help and suggestions.

    Hi Developers,
    * I am continiously running and processing more than 2000 XML files by using SAX and DOM.....
    * My process is as follows,
    - Converting the XML file as Document object by DOM....
    - And that DOM will be used while creating log file report, that log file will be created after executing all XML files..
    * After processing approx 1000 files, it throws *"java.io.IOException: Too many open files" in LinuX system* ....
    * I have googled more and more in all sites including sun forum also, but they are telling only to increase the system config by ULIMIT in linux....If i increase that its executing well without exception........
    * My question is, Is it possible to do it by JAVA code itself or any other VM arguments like -Xms512m and -Xmx512m.....
    * Please let me know , if you have any idea.....
    Thanks And Regards,

  • WLS 10.3.5 on RHEL 5.4, SocketException: Too many open files

    Hi
    I'm running Weblogic server 10.3.5 on Red Hat Enterprise Linux Server release 5.4 (Tikanga), with Java jdk1.6.0_27.
    My order handling application, when receiving client orders, needs to make outbound SOAP calls to fulfill the order. During a performance test, we got following errors:
    ####<Feb 10, 2012 2:28:41 PM ICT> <Critical> <Server> <KKMOMAPP2> <KKMOMPE2> <DynamicListenThread[Default]> <<WLS Kernel>> <> <> <1328858921806> <BEA-002616> <Failed to listen on channel "Default" on 172.24.106.81:4095, failure count: 1, failing for 0 seconds, java.net.SocketException: Too many open files>
    I monitored the java process of this application, when the "Too many open files" error happened, it had 1388 open file descriptors, among which 655 were sockets.
    I also monitored the total open file descriptors of the weblogic user account, the count was around 6300 during this error.
    These numbers are far smaller than the file limits configured on OS:
    - Under weblogic account, ulimit -n shows 65536
    - /proc/sys/fs/file-max shows 772591
    - Following lines are already in /etc/security/limits.conf
    weblogic soft nofile 65536
    weblogic hard nofile 65536
    weblogic soft nproc 16384
    weblogic hard nproc 16384
    I did another test using a simple java program to open large number of sockets under weblogic account. It has no problem to open 15,000 sockets. It seems the file descriptor limit is indeed quite high, but for some reasons, the Weblogic process fails even when it has merely 1388 open files. Are there other Linux or Weblogic parameters I should tune? Or anything else I missed?
    Thank you very much

  • Java.util.zip.ZipException: Too many open files on Linux

    Hi,
    We have web application running on Caucho's resin server on jdk 1.5.0_11 and Red hat Linux. We are noticing that java process is running out of file handles within 24-30 hours. We have file limit of 5000 which it consumes in 24 hours throwing 'java.util.zip.ZipException: Too many open files'.
    I have made sure all sorts of file handles are closed from application point of view. Here is the snapshot of lsof (list of file handles) from java process. The following list keeps growing until it runs out of limit. Do you have tips/suggestions on how to mitigate this problem (considering we dont want to increase ulimit for this process)? Also, can you make out any thing more from the description of file handles like, are they unclosed POP3 connections or URL connection to external sites?

    Finally we resolved this issue. It was oracle driver which had some compatibility issue, we upgraded our Oracle client driver to newer version, and this fixed the problem. Base line, there was nothing wrong with application code, code was doing good resource clean up, but oracle driver was leaking handles per every connection.

  • Runtime.exec - Too Many Open Files

    System version : Red Hat Enterprise Linux 2.4.21-47.ELsmp AS release 3 (Taroon Update 8)
    JRE version : 1.6.0-b105
    Important : the commands described below are launched from a Web application : Apache Tomcat 6.0.10
    Hello,
    I'm facing a problem already known, but appearantly never really solved ??!! ;)
    When I invoke many system commands with the 'Runtime.exec(...)' method, there are open files that are not released (I can see them with the "lsof" system command) .
    At the end, the unavoidable "too many open files" Exception.
    The lauched commands are "ssh ... " commands.
    In the topics relating to this problem, the solution is always to close all Streams / threads and to explicitely invoke the method "Process.destroy()".
    My problem is that this is what I do ! And I can't do more...
    Here is the code :
           Runtime rt = Runtime.getRuntime();
           Process process = rt.exec("ssh ...");
            // ProcessStreamHolder extends Thread and reads from the InputStream given in constructor...
            ProcessStreamHolder errorStream = new ProcessStreamHolder(process.getErrorStream());
            ProcessStreamHolder outputStream = new ProcessStreamHolder(process.getInputStream());
            errorStream.start();
            outputStream.start();
            exitValue = process.waitFor();
            try {
                errorStream.interrupt();
            } catch (RuntimeException e) {
                logger.warn("...");
            try {
                outputStream.interrupt();
            } catch (RuntimeException e) {
                logger.warn("...");
            try {
                process.getInputStream().close();
            } catch (RuntimeException e) {
                logger.warn("...");
            try {
                process.getOutputStream().close();
            } catch (RuntimeException e) {
                logger.warn("...");
            try {
                process.getErrorStream().close();
            } catch (RuntimeException e) {
                logger.warn("...");
            process.destroy();Does someone know if my code is wrong or if there's a workaround for me ?
    Thanks by advance !
    Richard.

    Don't interrupt those threads. Close the output stream first, then wait for the process to exit, then both threads reading the stdout and stderr of the process should get EOFs, so they should exit naturally, and incidentally close the streams themselves.

  • "Too many open files" Exception on "tapestry-framework-4.1.1.jar"

    These unknown references are sometimes released automatically, but sometimes not.
    And I get "Too many open files" exception after using my application for a few hours.
    The number of the unknown references increases as I access to my webwork or just hit on "F5" key on my browser to reload it.
    I tried different types of browsers to see if I could see any differences in consequence, and in fact it differed by the browser I used.
    When viewed by Internet Explorer it increased by 3 for every access.
    On the other hand it increased by 7 for each attempt when accessed by FireFox.
    I have already tried optimizing the max number of file discriptors, and it solved the "Too many open files" exception.
    But stil I'm wondering who actually is opening "tapestry-framework-4.1.1.jar" this many.
    Could anyone figure out what is going on?
    Thanks in advance.

    Hi,
    Cause might The server got an exception while trying to accept client connections. It will try to backoff to aid recovery.
    The OS limit for the number of open file descriptor (FD limit) needs to be increased. Tune OS parameters that might help the server to accept more client connections (e.g. TCP accept back log).

  • Intermittent too many open files error and Invalid TLV error

    Post Author: jam2008
    CA Forum: General
    I'm writing this up in the hopes of saving someone else a couple of days of hair-pulling...
    Environment: Crystal Reports XI Enterprise / also runtime via Accpac ERP 5.4
    Invalid TLV error in Accpac
    "too many open files" error in event.log file
    Situation:
    Invalid TLV error occurs seemingly randomly on report created in CR Professional 11.  Several days of troubleshooting finally lead to the following diagnosis:
    This error occurs in a report that contains MORE THAN 1 bitmap image.
    The error only shows up after 20 or more reports have been generated sequentially, WITHOUT CLOSING the application that is calling the report.  In our case the Invoice Report dialog within Accpac.  This same error occurred in a custom 3rd party VB.NET app that also called the report through an Accpac API.

    after getting this message you need to do 2 things:
    1. delete the current workspace because it contains some bad data in one the config files - failure to delete the workspace will result the error message to appear even if trying to upload a single file.
    2. add to DTR files in groups - no more than 500 in a single add.

    It's only when having the server partition compiled that this happen.

    Hi,
    running a server partition that reads a configuration file,
    and apparently doen't close it after, I have that exception:
    SYSTEM ERROR: System Error: Too many open files, opening '....'with mode
    'r'
    Class: qqos_FileResourceException
    1) Is there such a limit, or does this rely only on the OS one ?
    2) How is this error not trapped, as I only got itinteractively, whereas
    my server log does a exception trap/segmentation fault,

    Hi Jean-Paul,
    As described in the Technote 10981 some Forte programs (Nodemanager and
    router) handle correct the high-file descriptor-use problem. It is possible
    that Forte interpreter do it correct too.

    Thank you, bye,

    Hello Marco.
    When you try to deploy an EAR weblogic server at the time of deployment unjar's it and compiles the files and so on. Every Operating system has a limit on how many number of files can be opened by a process. If your EAR is big then the number of files which WLS will unjar will also be large hence you hit the limit. By splitting your ear into 2, you are splitting wls task into smaller parts, which means the number of files it unjars at a time is less.
    The following note tells what needs to be done to avert this issue.

  • Getting java.io.FileNotFoundException: Too many open files

    I have search for different strings in a file again and again. I am using following code:
    try
                   fileReaderObject = new BufferedReader(new FileReader(fileObject));          
                   String inputLine;
                   while ((inputLine = fileReaderObject.readLine()) != null)     
                        if (zipCode.equalsIgnoreCase(inputLine.split("\t")[0]))
                             s = inputLine;     
                             fileReaderObject.close();
                             return s;
                   fileReaderObject.close();
              catch (Exception e)
                   Utils.writeMessage(e.toString());               
                   e.printStackTrace();               
              }But getting java.io.FileNotFoundException:file/emp_info (Too many open files)
    1. Whats the main reason of this exception and how can it be removed.
    2. Is there any way to move the pointer to the start of the file. I tried reset() but its seems to have some problem.
    -vc

    A hint: your fileReaderObject is not closed if an exception occurs.
    Lacking desctructors, the Java-ish way is to close in a finally clause.
