    Hi!
    To increase the FDs available for DS, edit the Configuration --> Performance Settings and increase the no. of FDs available for DS. please check if you havent done this.
    I faced the similar problem. Increased the system limit(/etc/system) and DS setting, but was still recieving the error message time to time, which disappears automatically, when FDs get freed. The server is quite a busy LDAP server.
    Can someone comment how can i see the actual Fd utilisation on a Solaris 8 system.
    I have been checking like:
    ls -l /procs/fd | wc -l
    and by:
    ls -l /procs/pid-of-slapd/fd | wc -l
    But always find the Fds in use to be quite lesser than the limit specified 4096.
    Thanks for sharing.
    Cheers!

  • PR_Accept() failed, error -5971 (Process open FD table is full.)

    I am working on a web app which uses the SunONE directory server for
    some authorization. Sometimes it happens that the webserver just hangs
    with no errors in the webserver log. In the slapd error logs I do see
    the following exceptions :
    PR_Accept() failed, error -5971 (Process open FD table is full.)
    I am not sure why is this happening? What could be the problem? I am
    assuming FD means the file descriptor? One bug we found in the app is
    that it tries to add a new user in the LDAP even if its there. I do get
    "add value to attribute type nsRoleDN in entry .....: duplicate value"
    exceptions, but thought its harmless. Could this exception be causing
    something?

    Hi,
    I had exactly the same error message. I did not find the cause of this after spending a lot of time looking around. I only know it is a file descriptor table problem. The sun one directory server access log, however, did not have the number of file descriptors count reached maximum. I am very much puzzled by this. Did you find out why yet?

  • PR_Accept() failed, error -5971

    We have a iPlanet 5.1 sp3 directory server.
    There are very few active users. However it recently failed with the error: "PR_Accept() failed, error -5971"
    What causes this?
    How does the DS protect itself from misbehaving clients.. I am mystified how the table of 4096 FDs the UNIX system has gets filled up. Surely the DS is freeing them up!

    Hello,
    Did anyone reply to you about this? I have almost the same problem:
    PR_Accept() failed, error -5974 (Insufficient system resources.)
    Thanks, Firdaus

  • PR_Accept() failed, error -5974 (Insufficient system resources.)

    How can I go about determining exactly which resource was insufficient? Or has anyone encountered this and has an idea of typical reasons?
    With about 1000 connections this morning, I saw this in the log:
    PR_Accept() failed, error -5974 (Insufficient system resources.)
    Our setup:
    iPlanet Directory Server 5.1
    HPUX platform - 6 gigs ram, dual 100mb nics, plenty of disc space.

    Thanks Gary. I was going to set the ulimit and the hard and soft limits on the OS. I had done this before on a Solaris system, but with HP, I'm not sure where the equivalent of /etc/system is. I may have to check with our HP guys.
    BTW, here's the output of idsktune. I don't see any warnings for only 64 threads being available. We are going to try 5.2 Patch 4, but we cannot apply it in this environment yet -- still doing a POC. Thanks!

  • Error message in .docx : 'Open XML file cannot be opened because there are problems with the contents. Details Unspecific error Location: 2'

    I have put a lot of work into a docx document on my Mac, but now can't open it as it gives the error message: 'the Open XML file cannot be opened because there are problems with the contents. Details, Unspecific
    error, Location: 2'
    When opening the original file the message said: 'this file contains word 2007 for Windows equations' etc. but I managed to track changes fine, and saved, closed and re-opened it numerous times without problem. Some graphs seemed moved, and various formulas
    were illegible, but no other weirdness was observed.
    I have microsoft 2008 installed on my Mac OS X version 10.6.8.
    I've tried to fix it using various solutions suggested here, but am afraid am too IT illiterate to have had any luck, please help I'm new to all this!

    Usually means you are running out of system resources e.g. not enough file descriptors, not enough TCP connections. Please review your kernel tuning parameters to see about increasing them.

  • HT4436 i have a problem with my Macbook Pro. When i tried to open it, something appeared : "enter your system lock PIN code to unlock this Mac". What should i do?

    i have a problem with my Macbook Pro. When i tried to open it, something appeared : "enter your system lock PIN code to unlock this Mac". What should i do?

    Question is did you lock your Mac from Find my iPhone using iCloud or is the Macbook really yours?
    If you have in fact locked your Mac using Find my iPhone on iCloud then you will need to enter the PIN you have set when you locked the Mac.
    *If you have not iniate the remote Lock then someone else has used your Apple ID and Password to lock your mac.

    Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
    least ten seconds, until the Apple logo appears.
    - Reset all settings

  • Problem with Drive Encryption for HP ProtectTools - Error EE050014

    Hello!
    I have a problem with starting up my HP.
    I am using a HP Probook 4530s, have had it for approximately 2 years now - this is a new problem that has never occured before.
    On startup, after swiping my finger/entering the password at the HP Protecttools screen, I get an error screen titled "Mcafee endpoint encryption" saying "Error 050014 file access error". As far as I'm concerned this is not a Mcafee product although it mentions Mcafee, and I will not receive any help from their support forums. All I can do is press enter, then the cursor is locked in place and nothing but restarting the computer can be done, and then the process repeats. 
    Before this error occured, I was going through files with an anti-malware program and it is possible I may have deleted something that might have triggered this, however since I cannot access the desktop or anything it is impossible for me to look into that.
    I have been desperately looking for a solution for a while now but have come up with nothing solid. Any help is greatly appreciated!
    Regards!

    Hello matroid,

  • Problems with a QuickTime movie file.  Error 2048 message

    I am having problems with a QuickTime file.
    The file is on a TDK 4GB pen drive.
    I can access the file without problem directly from the pen drive.
    I am using a Sony VAIO Laptop running Windows 7.
    QuickTime version 7.71.80.42.
    When I transfer the file to a folder or upload to send via e-mail on Hotmail and then try to open it I receive an Error 2048 message - "Couldn't open the file.......because it is not a file that QuickTime understands.
    Any help would be appreciated.

    You should be fine: a standard DVD can contain up to 120 minutes of video, but this includes menus etc.
    iDVD is not concerned with file sizes, just length. It will automatically compress the iMovie file to the standard DVD format of mpeg2 - which is 4.7GB for 120 minutes!
    I have once made a family DVD 115 minutes long, but after the family either protested or fell asleep, I have tried to keep them under 75 minutes!

  • Problem with shortcut....fatal error

    itune 8.1.1 upgrade froze on installation. Now I get the above message when trying to reinstall/config itunes or any new program. Have tried restore etc but no luck. Any ideas.

    I ran into the same problem, but I think I have the solution. First, the problem isn't with iTunes, its an access problem with Windows XP. I tried to run the iTunes program from the Program Files, and I received an "Access Denied" error.
    If you try to open the Program Files in My Computer\Local Disk(C:) and receive an "Access Denied" Error, that is why you are receiving a "shortcut problem/Fatal Error during installation".
    Here is how I corrected it:
    1) Shut down the computer and restart it in "safe mode". I had to look up how to do this, but I pressed F8 when it was restarting and I highlighted the "safe mode" and started the machine. The icons will be large, but ignore it.
    2) Open a user that has administrative access -- I used the one user that has access to itunes.
    3) Go to My Computer\Local Disk (C:) and right click on the "Program Files" folder. Select "properties" at the bottom.
    4) Go to the Security Tab
    5) At the top you should see one or two users that have access to the Programs File. One will be the user that itunes works on. Click Add, then click Advanced, then click Find Now.
    6) At the bottom should appear a list of users. Select a user on which itunes doesn't work. Click Ok, then click OK again.
    7) Give that user full access to the Program File by putting a check mark in the Full Access box.
    8) Repeat for the remaining users.
    9) Restart computer in normal mode.
    10) Go into a user that had problems and click the itunes icon, and it should run.
    It worked for me, I hope it works for you.
