Message server hogs CPU when clients are disconnected

Hi, I have a problem where java process for the Sun One Message Queue (3.0.1) hogs the cpu when a client is disconnected. I am trying to use the MQ in an environment where clients might crash and try to reconnect in an unpredictable fashion. Most of the time, when I kill the client and restart it, I do not see the problem. Sometimes, however, doing so makes the java process of mq take almsot 100% of Cpu and it does not go down unless i kill the mq process.
I am using asynchrnous message listeners with transactions, on a persisted queue, although i saw this problem when transaction was disabled.
Does anyone have any idea what might be the source of the problem? I hope it's just a matter of configuring MQ correctly, but i could figure it out. Help would be greatly appreciated.

Are you running the enterprise edition and
using round-robin queues with multiple
receivers ?
If so, you may be running into a timing related bug
in multiple receivers that has been fixed in service
pack releases of the software
You should contact sun support to discuss testing with
the lastest service pack.
If not, can you provide more information (platform,
# and type of receivers, etc) on how you are using
the product
Thanks

  • How to prevent mail app on OS X & iOS from automatically marking email messages as read just when they are selected either intentionally or not

    Good morning guys
    is there a way to prevent mail app on OS X & iOS from automatically marking email messages as read just when they are selected either intentionally or not
    thanks

    On OS X, You are able to hide the preview window on the right in normal mode, or on the lower side in classic mode, by simply putting your cursor on the thin bar which is in between, and then make it as small as possible, so it goes away.
    Then your messages won't be automatically read when clicked once, but only if you click them twice and a new window with the message opens.
    Also, you are able to mark them as unread again, which is a silly workaround, but possible.
    You can do that by right clicking and select 'Mark as...' -> unread.
    On iOS, I'm not sure..

  • MDNS responder hogging CPU when connected to network

    Hi all.
    It seems whenever I'm connected to my work's network (either via wired or wireless) my mDNSResponder service starts hogging CPU. It generally starts at 0 and works its way up to 70-80% total CPU usage. I can kill it but within a few seconds it starts back up again.
    Any idea what the problem is or how to fix it? This has never been a problem in the past, and as far as I'm aware there have been no changes to the network.
    Thanks!

    My first psychic guess would be a messed up .cache, but...
    mDNSResponder (also known as mdnsd on some systems) is a daemon invoked at boot time to implement Multicast DNS and DNS Service Discovery.
    mDNSResponder listens UDP port 5353 for Multicast DNS Query packets.
    When it receives a query for which it knows an answer, mDNSResponder issues the appropriate Multicast DNS Reply packet.
    mDNSResponder also performs Multicast DNS Queries on behalf of client processes, and maintains a cache of the replies.
    mDNSResponder has no user-specifiable command-line argument, and users should not run mDNSResponder manually.
    To examine mDNSResponder's internal state, for debugging and disagnostic purposes, send it a SIGINFO signal, and it will then dump a snapshot summary of its internal state to /var/log/system.log, e.g.
    sudo killall -INFO mDNSResponder
    Also, not sure if this applies to OSX or not...

  • After installing 10.5.6, finder and quicklook server hog cpu for 10 minutes

    I installed 10.5.6. Now upon every restart the Finder and Quick Look Server use 60-80% of my cpu for 5-10 minutes. This means that I can't really do anything until these processes are done because they cause constant delays. This did not happen in the previous version of Leopard, and if it's intentional on the part of Apple, it's a mistake. Very very annoying. Any ideas how to get this to stop?

    stuartwgibson,
    How did you install 10.5.6?
    If you used "Software Update," you might want to try installing the Mac OS X 10.5.6 Combo Update.

  • CSM : Sorry server and Stickyness when reals are overloaded

    Hi,
    I have a portal of eight real servers and one sorry server, which should redirect new user to another portal, in case of an overload condition of all eight real servers. Server load is measured on each real server using a custom developed agent, which basically measures the real CPU load. If a real server experiences an overload, the local agent uses the CSM XML interface to set the maxcons value in the CSM to stop accepting new connections. However, I want to continue accepting sticky connections (request with a valid cookie). The experience shows that the CSM does accept to create new connections to real server reaching maxcons, even if a cookie exist.
    This causes a problem if we want to redirect NEW users to another portal in case of overload, but to keep EXISTING users in the server farm, even if the number of connections could increase slightly above maxconns...
    How can I solve the problem ?
    Thank you
    Yves Haemmerli

    Hi Thomas,
    Thank you for your comment. I also understand this behaviour like you, however this can have a devastating effect in a global portal environment. Imagine, you have three portals distributed over the world, each having let say 8 real servers. In the real life, it is seldom to replicate data in real time between data centers, due to the distance. However, the user roles and customized bookmarks and other user-specific settings are replicated. This allows to provide a global portal to users. But if a user connects to one particular regional portal, he has to stay on this portal for the duration of the whole browser session, do you follow me ? OK, now imagine that all 8 real servers in a portal reach the maxconns, because 10'000 users are connected to the portal. For new users (users with no sticky cookie), we want to send them to another regional portal. This is achieved with the global site selection provided by the GSS for example. But for existing user already connected to the overloaded portal, we want to KEEP them on the portal ! else, as the user browser continuously opens and closes TCP sessions, all 10'000 users will be immediately transferred to the other regional portal! This means the the other regional portal will becom overloaded as well, while the first portal load will be droped to zero very quickly ! Then, we not only create a situation where users loose their data by being transferred to another portal, but we also create a oscillations in the portal load !
    I really don't know if there is a mean to solve this problem...Do you have any idea ?

  • Unity message server is offline when tyring to listen to messages from a phone, email delivery and listening to messages in outlook works fine

    The problem started last night when our Exchange queues backed up due to a virtual memory error and we had to do a failover. I see the following item in the application log repeating.
    Source: CiscoUnity_CsServices
    Category: run

    When I look in the services section it shows all the services as started.  I've tried manually restarting services and have rebooted the server multiple times.  The web interface works just fine as well.  I haven't been able to find any thing online that matches this.  Has anyone seen this before or knows how to fix it?

  • How to change VM Server IP address when VMs are provisioned

    Dear all,
    I have deployed some Oracle VM servers and provisioned some VMs running upon on them.
    However, the user requests to change the management IP address of these VM servers. How can I do it?
    In my practice, I need backup all VMs and remove them. Then remove these VM servers from pool. Then change management IP...add them into server pool...restore VMs from backup....
    Pls correct me if I am wrong.
    Thanks,
    Mike

    You don't have to remove or backup/restore the VMs. Just migrate them to another server (if shared storage) or to Unassigned VMs (if local storage). The machines should be stopped (not suspended). There is a bug where a suspended machine can migrate to Unassigned VMs but can't migrate back (without manual intervention on the console). If you are changing the pool virtual IP, you have to delete/recreate the server pool. This will lose the "simple names" of the disks and ISOs, so record them before deleting the pool. It will not remove the Repository contents. After recreating the pool, you can rediscover the server, present the repository and refresh its contents.

  • Files locked when Windows clients are connected to ML Server via smb

    Hi,
    I've got a problem with windows 7 clients that are connected to my MacMini Server.
    When they open files on a shared folder, and modify them, files are locked when they try to save them.
    I think it might be the op-lock option present in older versions of Mac OS X Server that can be involved, but it disapeared in Lion and older version of OS X Server.
    Does someone knows how to activate/deactivate this option, or does someone already got this problem?
    Server is a MacMini with 10.8.5 + Server 2.2.2
    Clients are Windows 7
    Thank a lot for your answers
    Bertrand.

    Officially, Adobe does not support opening or saving files to a server --- because so many different things can go wrong with networking.
    The permissions error means that the file/directory permissions are incorrect on the file server, or that the OS or server is incorrectly reporting file/directory permissions.
    Photoshop does more error checking than most applications, because we have seen so many problems in the past, and don't like applications silently losing or damaging files (which we see in other applications).

  • Server Cannot Detect that the Client is disconnected, why?

    From what I've read, in order to make server "know" that a client is disconnected, you have to make server "write" to client socket to eventually catch an ioexception.
    So I write a simple server program and a simple client program. The server "writes" to the client every 10 secs. Now I start the server and client, I can tell on the client side that for about every 10 secs, the client gets the message.
    Now I terminate the client program. The server still keeps writing to the client. It's my understanding that after 1 min or so I should see an ioexception. However, 10 minutes passed and the server still keeps writing...
    Why is this happening? Did I miss something?

    I think it happens because the port is still open
    even after the client is closed.And you should not
    get IOException when you send a packet over a open
    port.Err, no, you should get a SocketException when you send data to a port which has already been closed or reset by the peer.

  • Detecting when users connect/disconnect

    I have a client application that communicates via EJB and also
    subscribes to JMS topics. I need the server to programatically
    detect when a client connects and to JMS and when they go away.
    We want to keep course grained stats on how long someone is connected.
    The WebLogic console shows when a user is connected and it their

    to pay someone to stare at the console window with a stop watch
    and time connections.
    How can I programmatically detect when clients connects and

    That may be a good idea but what are we supposed to do in the meantime.
    any work arounds etc??

    Question: Users are able to connect ADRMS Server and restrict permission to their documents without any issue. BUT CANNOT open the restricted document even by the owner/administrator. Whenever they try to open restricted docs a message appears " Cannot

    So far I think clients computers are not able to retrieve the rms url.
    Kindly, suggest how should I approach to the solution.
    NB:- I am  new to ADRMS.

    Hi Ashim Kumar Nath,
    Have you registered SCP when installing ADRMS? If you can't remember, you can check this running ADSI Edit, connect to the configuration container in verify if those nodes exist CN=Configuration [server name], CN=Services, CN=RightsManagementServices,
    CN=SCP. Right click on SCP and verify that serviceBindingInformation contains your https://rms.company.com/_wmcs/certification server name.
