DS 6.3.1 thousands of open established connections

Hello everyone,
I have been fighting a problem on our backup server. Every night i get about 500 emails stating a problem with ldap. The error is as follows:
libsldap: Status: 81 Mesg: LDAP ERROR (81): Error occurred during receiving results. This may be due to a stalled connection.
I have found that this causes thousands of open connections on the server to my ldap server. Here is a sample of our netstat output:
datasrv.32946 ldapsrv01.ldaps 49640 0 49640 0 ESTABLISHED
datasrv.33599 ldapsrv01.ldaps 49640 0 49640 0 ESTABLISHED
datasrv.32947 ldapsrv01.ldaps 49640 0 49640 0 ESTABLISHED
datasrv.34106 ldapsrv01.ldaps 49640 0 49640 0 ESTABLISHED
datasrv.33600 ldapsrv01.ldaps 49640 0 49640 0 ESTABLISHED
datasrv.33601 ldapsrv01.ldaps 49640 0 49640 0 ESTABLISHED
datasrv.33602 ldapsrv01.ldaps 49640 0 49640 0 ESTABLISHED
I just rebooted my backup server (datasrv) and it currently has 526 connections to the ldap server (ldapsrv01). However, this number is up from 494 from an hour ago. I find that the longer the server is up, the more i get. I ended up with ~14500 before i rebooted the server. I think this may be causing my stalled connection, but i am not sure what is causing so many open established connections. Anyone have any info on this error? It would be greatly appreciated.
Thanks,
Kyle

Please ensure idletimeout is set. A recommended value for idletimeout is 15-30 minutes. This means, if a connection is idle for longer, it will be closed from the DS side and the file descriptor reused. If you have a load balancer in place which is configured to do health checks,often the LB just drops the connection without closing. With an idle timeout set you can workaround this issue.
Your connections are with LDAPS, so maybe setting ioblocktimeout will help as well. This problem is detailed in this bug report.

  • ACE failed probe and established connections

    Hello,
    I have four ACE 4710. Each pair of ACE is in one geographical location. Probes are configured so that it is checking regular regex (HTTP GET).
    When there is need rserver update we change text in our testpage.html (for ie. from "OK" to "SUSPEND" ) so that probe detect fail.
    In fact rservers are still operational, but should not accept new connections. This works fine.
    BUT I observed that established connection/sessions did not end up after probe fails. ACE probably wait for openned/established connections to end up and it is what I am askign for.
    What happens if probe fails but in fact rserver is operational? I thought that if probe fails it also end up/cut all established connections to rserver. But seems it is not true. Does anybody has this experience?
    Thanks for your opinion.

    Hello Jan,
    if I understood correctly what you're looking for is domented in the area for the failaction command which actually makes the ACE behavior on this aspect configurable:
    http://www.cisco.com/en/US/docs/app_ntwk_services/data_center_app_services/ace_appliances/vA4_2_0/configuration/slb/guide/rsfarms.html#wp1117375
    indeed the default behavior of the ACE is to take a  failed real server out of load-balancing rotation for new connections  and to allow existing connections to complete.
    Hope it helps,
    Francesco

  • Unable to open any websites from the search engines. the ones I have tried are google, yahoo and ask. They opened until recently. The popup says" Firefox can't establish connection to the server." Ask worked last night but is not working now.

    When I try to open a web site from one of the search engines a pop up shows stating that Firefox can't establish connection to the server. I can't open any websites through any of the search engines.

  • Whenever I try to open Firefox it says cannot establish connection, maybe your firewall is preventing us from accessing the web.

    Whenever I try to open Firefox it says cannot establish connection, maybe your firewall is preventing us from accessing the web. Even though I've let Firefox through my firewall, this message still appears. And whenever I try to redownload it, it just says installation failed. It does this with all installations... Is there something wrong with my computer? How do I fix it?

    Sometimes you only disable the user interface of security software, but the firewall or anti-virus services are still running in the background.
    It is possible that your security software (firewall, anti-virus) blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.
    Remove all rules for Firefox and the plugin-container from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process and the updater process.

  • Problem: Failed to open the connection. Error Code 0x800002F4 (-2147482892)

    Problem: Failed to open the connection. Error Code 0x800002F4 (-2147482892)
    This is on two (2) separate machines. These are NEW INSTALLATION development work stations (laptops). One is Vista (Visual Studio 2008 / Crystal Reports 2008), and the other is Windows XP Pro (Visual Studio 2003 / Crystal Reports XI R1).
    I am using EXISTING CODE (established over several years), and EXISTING REPORTS (established over several years). Old development station was XP Pro, as above, and still exists, and still works fine.
    I can open the report in Crystal, and see the results just fine. Data for the report is obtained via ODBC.
    Can someone identity the actual error by the Error Code above, and advise. Thanks You in Advance.

    Ok, so let's start at step 1:
    SP 1 just released and I'd recommend applying that. The SO is available from here:
    https://smpdl.sap-ag.de/~sapidp/012002523100010503722008E/cr2008_sp1.exe
    For future reference, msm matching the above SP is here:
    https://smpdl.sap-ag.de/~sapidp/012002523100011715292008E/cr121_mm.zip
    and msi is here:
    https://smpdl.sap-ag.de/~sapidp/012002523100011722132008E/cr121_redist_install.zip
    Step 2: a few questions:
    a) I am not sure what CR SDK you are using; RDC, .NET? I suspect that you are using the CR assemblies for .NET, but do confirm.
    b) what is the database you are connecting to?
    c) is this a web or a win app?
    Step 3:  As the error can mean any number of things (to me it's just means something went wrong during the attempt to connect to the database...), the solution may vary, however the troubleshooting steps remain quite consistent:
    1) Do make sure the report is indeed working in the CR 2008 designer (e.g.; make sure "saved data" is not enabled.
    2) Try a simple new windows app with one of your reports. See if you have a report with no subreports and use it
    3) If that works, use a report with subreports
    4) If the above does not work in (1) above, create a new report to the same ODBC connection, do not code any database connection - let the report prompt for the logon parameter (PWD)
    5) Run the new report in your new app, enter the PWD when prompted
    6) If this works, add your database logon code
    7) If that works, add your original report (again, preferably with no subreports)
    8) If that fails, ensure that the subreport and main report use the same database connection type (ODBC)
    9) If it works, see if you can determine the difference between your old app and the new app.

    ========================================

    Io exception: The Network Adapter could not establish the connection..
    I'd check in tools->embedded oc4j server preferences (current workspace app / data sources) and do a refresh now.
    Next, make sure your app module config files reference the right connection by right clicking the app module and selecting configuration. lastly, make sure the project points to the right database connection by right clicking project -> properties, business components.

  • Named Pipes Provider: Could not open a connection to SQL Server

    We are running into an error on a SQL request from SQL-IDA to the SQL-IDB server. Both servers are on Windows 2005 with MS SQL Server 2003 SP3.
    OLE DB provider "SQL-IDA" for linked server "SQL-IDB" returned message "Login timeout
    expired".
    OLE DB provider "SQL-IDA" for linked server "SQL-IDB" returned message "An error has
    occurred while establishing a connection to the server. When connecting to SQL Server 2005,
    this failure may be caused by the fact that under the default settings SQL Server does not
    allow remote connections.".
    Msg 53, Level 16, State 1, Line 0
    Named Pipes Provider: Could not open a connection to SQL Server [53].
    It seems to suggest that SQL-IDA cannot find the network path to SQL-IDB. We've followed the steps in this article http://support.microsoft.com/default.aspx?scid=kb;EN-US;914277 but it did not resolve our issue. Is it possible that the MSDTC dynamic port range
    should be set to a specific range on both servers?
    Any help is greatly appreciated.
    Albert

    Hi Albert,
    Can you try to use the SQL Server Management Studio on server ‘SQL-IDA’ to connect to the instance on server ‘SQL-IDB’ to see if it works or not?
    There are possible reasons to error 53:
     a) typo in the server name, or using "/" rather than "\" between server name and instance name, e.g. "myserver/myinst" is not correct.
     b) name resolution to the server name is not correct, "ping -a yourserver" would tell if that's the case
     c) The server machine is firewall'ed and file sharing is not in the exception list. You need put "File and Printer Sharing" in exception.
    For more information:
    Named Pipes Provider, error: 40 - Could not open a connection to SQL Server (Microsoft SQL Server, Error: XXX).

  • FTP exception: Can't open passive connection: Permission Denied

    I have a File sender adapter, with FTP as transport protocol.
    The adapter polls a directory each 60 seconds.
    All works perfectly but <b>sometimes</b> I get the following error :
    Channel CC_GBL_FlatFileSender: Error connecting to ftp server ...: com.sap.aii.adapter.file.ftp.FTPEx: 425 Can't open passive connection: Permission denied.
    And 60 seconds after, no more error.
    Any idee of why I get this error occasionally ?
    In the sender file adapte, data connection is set to Passive.  Do I have to set it to Active ?
    Thanks in advance,
    Laurence

    Hi
    Data Connection
         -  Active
    In active mode, the server establishes a data connection from its data port, port 20, to an end point chosen by the client.
         -  Passive
    In passive mode, the client establishes a data connection to the port required by the server.
    The default setting is a passive data connection. Only change this setting if you have a specific reason. This is what is recommended by SAP.
    It is possible that Passive FTP mode may terminate session.
    In this mode the server "listen" on a data port (which is not its default data port) and to wait for a connection rather than initiate one upon receipt of a transfer command. The response to this command includes the host and port address this server is listening on.
    In the FTP protocol two ports are normally used, 20 and 21.
    Port 21 is the control channel in which requests such as PUT, GET, and PWD are sent to the server.
    Port 20 is the data channel in which actual files, folders and directory
    listings are sent.
    Normally, when you connect to an FTP site, the site establishes the data
    connection to your PC (the client) on Port 20. However, if the site allows
    passive transfers, you can have your PC establish the data connection. It is
    recommended that you use passive mode for most transfers.

  • Cannot establish connection with Oracle database

    Hello
    This is the first time I use BOE server with Crystal Report to execute some tests, and one issue is blocking me now, and I am not even sure if this is the right Forum where I should post it.
    I installed BOE server XI 3.1 SP4 on Linux machine (new installation), and then I uploaded some existing Crystal Report templates that are working fine on another BOE server. Those CR templates have to establish a connection with a remote Oracle database to get the data, and we pass all credentials for this purpose.
    The first time I run my first test I received this error that I could not find anywhere on the web :
    ErrorLog 2011  8 10  7:05:52.505 14215 356 (Administrator:82) (../reporthandler.cpp:12462): CReportHandler::buildReportViewerError: CSResultExceFailed to open the connection." FileName:"../reporthandler.cpp" LineNum:12458 ErrorCode:756 ErrorMsg:"Failed to open the connection.
    {FBAD55EE-BEAF-11E0-BC1C-005056813A72}.rpt" DetailedErrorMsg:""
    I believe that the CR was not able to establish the connection with Oracle, so I install Oracle Client on the same machine (test remote connection ==> pass), I set the ORACLE_HOME variable, and I edit the file <installation_home>/ bobje/java/CRConfig.xml to add the path to ojdbc14.jar, and finnaly restart the tomcat server. However I am still getting the same error message.
    Is there any hint that can help me troubleshooting this issue?
    Thank you

    do the reports use native oracle connectivity or JDBC ?
    what version of Oracle client did you install ?
    was it 32bit or 64bit client ?
    what your LD_LIBRARY_PATH variable set to ?
    what does it say in the CMC when you look at CR report's DB properties ?

    Transaction [ 0x140002( 0x4f4cfd87.0x7b890 ) ] aborted due to status [1021001].
    I have tested that the ODBC connection can connect to the database. The sql query has been dumbed down to select '1' from dual. I have not included the word "select" in the query.
    Anyone seen this before? We are in the process of uninstalling the Oracle client completely and re-installing it to see if this solves the issue. We only installed the 64 bit version of the Oracle client. I am running on Windows Enterprise 2008 R2 - 64 bit. EAS, Essbase, EIS are all 64 bit installs. I believe Studio is the only one that is 32bit. However we are not currently using this product.
    Thanks,
    Mike

    Hi Mike,
    With Oracle Support's help, we got 3 of the 5 servers working now. We were using the Datadirect drivers but were configuring them wrong! You have to use the Standard Connection portion in the setup, specifying the Host, Port Number (1521) and the SID. We were using the TNSNames Connection which worked in the past, but apparently does not now.
    So I am down to 2 servers not working. They are both Windows 2008 R2 Enterprise 64 bit, running Oracle EPM Essbase 11.1.2.1. When I Open SQL in EAS it prompts for database (Essbase Server, App, DB) and when I hit ok it pops up with "Network error: Cannot Locate Connect Information For []". We did not do any of the suggestions in the document you linked to get the other 3 servers working. When you hit ok on that error, you then get another error stating, "There are no Data Sources defined. 'SQL data sources' option will be disabled". We do have datasources defined on the server.
    Any ideas?
    Thanks,
    Mike

  • Essbase Studio Error(1021001): Failed to Establish Connection With SQL Data

    Hi.
    I have trying to deploy a cube with Essbase Studio but I get the error: "*Error(1021001): Failed to Establish Connection With SQL Database Server*"
    My environment is Linux 5, Oracle 11g and EPM 11.1.1.2. Oracle database and Essbase was installed with diferent users. In the .bash_profile of hypadmin user (that install Essbase) I have set the following variables
    ORACLE_BASE=/u01/app/oracledb/product/11.1.0
    ORACLE_HOME=$ORACLE_BASE/db_1
    LD_LIBRARY_PATH=/usr/X11R6/lib:$ORACLE_HOME/lib:$LD_LIBRARY_PATH
    ORACLE_HOSTNAME=devbi.sigfe2
    PATH=$ORACLE_HOME/bin:$ORACLE_HOME/jdk/bin:$ORACLE_HOME/bin:/sbin:$ORACLE_HOME/opmn/bin:$PATH
    ORACLE_SID=orcl
    JAVA_HOME=/u01/app/installfiles/jdk1.5.0_19
    In my pc (windows xp) I can open Essbase Studio console, do the connection to Oracle database, get tables and create minischema, mesures and hierarchies (I can see the preview of hierarchies). Also I can create cubes with EAS and can connect with MAXSHELL to essbase.
    When I try to deploy the cube from Essbaes Studio y get the error "Error(1021001): Failed to Establish Connection With SQL Database Server".
    The Essbase Studio Log File say:

    Hi,
    If you type database SID in lowercase, try to reenter iot in uppercase. Strange, but I and my colleagues encounter this behaviour many times.

    Hi
    I am having problems connecting from my Master to the Local Distributor server both on Solaris 10

    Ok what am I mssing

    Hi,
    I am not quite sure where exactly you get an error. Are you trying to prepare an agent that connects to your newly installed LD?
    You did mention the following:
    I was able to ssh from master to LD with promptDo you mean you could login from the MS to the LD without password and got the OS prompt? What you have to make sure is that your ssh authentication works for the n1sps user (or whatever you have chosen during installation) from MS to LD and from LD to RA. That involves copying the public key from the MS n1sps user to the .ssh/authorized_keys files on the LD and RA. And after that, you should check the connections manually:
    1. From the MS: ssh <LD> ls -al
    2. From the MS: ssh <LD> ssh <RA> ls -al
    These both commands should work without any prompts and after that, you shouldn't get any error messages in SPS anymore.
    HTH,
    Michael
