  • debugging JBoss 100% CPU usage

    - by Nate
    We are using JBoss to run two of our WARs. One is our web app, the other is our web service. The web app accesses a database on another machine and makes requests to the web service. The web service makes JMS requests to other machines, aggregates the data, and returns it. At our biggest client, about once a month the JBoss Java process takes 100% of all CPUs. The machine running JBoss has 8 CPUs. Our web app is still accessible during this time, however pages take about 3 minutes to load. Restarting JBoss restores everything to normal. The database machine and all the other machines are fine, only the machine running JBoss is affected. Memory usage is normal. Network utilization is normal. There are no suspect error messages in the JBoss logs. I have set up a test environment as close as possible to the client's production environment and I've done load testing with as much as 2x the number of concurrent users. I have not gotten my test environment to replicate the problem. Where do we go from here? How can we narrow down the problem? Currently the only plan we have is to wait until the problem occurs in production on its own, then do some debugging to determine the cause. So far people have just restarted JBoss when the problem occurred to minimize down time. Next time it happens they will get a developer to take a look. The question is, next time it happens, what can be done to determine the cause? We could setup a separate JBoss instance on the same box and install the web app separately from the web service. This way when the problem next occurs we will know which WAR has the problem (assuming it is our code). This doesn't narrow it down much though. Should I enable JMX remote? This way the next time the problem occurs I can connect with VisualVM and see which threads are taking the CPU and what the hell they are doing. However, is there a significant down side to enabling JMX remote in a production environment? Is there another way to see what threads are eating the CPU and to get a stacktrace to see what they are doing? Any other ideas? Thanks!

  • Outlook 2010 email tracking

    - by Bill Hubbard
    I have outlook 2007. Is there a way in 2007 or the 2010 version to have all the emails posted to read for a certain contact. When I click history it takes about 2 minutes for it to load and is frustrating. As simple as this seems I simply want to see all the emails gone back and forth with a contact when I open that contact.

  • IIS large amount of time before loading

    - by Lukes123
    I am running an ASP.NET 3.5 website on IIS 6 with Server 2003. Whenever I modify any of the ASPX files, any page on the site then takes about 2-3 minutes before it starts to load. Even the smallest modification causes this to happen. Why is this?

    - by ssl
    Hi, I have a Linux machine which connected to an Active Directory on Windows server. I configured the NIC to get an IP from the DHCP (from the windows server) however, when I try to get nslookup on the Linux side it doesn't work (connection timeout), but on the same machine when I load windows and do nslookup it works. what can be wrong with my Linux configuration or Windows DNS configuration? note: I've configured my DNS to nonsecure and secure connections. 10x!

    Hello everyone, following problem deals with MS Windows Server 2008 R2 with Hyper-V: Does anybody have an idea how to log processes which cause CPU utilisation more than X percent?

  • Better way to quad+ boot operating systems?

    - by Wijagels
    I currently have Windows 7, Ubuntu 12.04, Fedora 17, and open SUSE installed. I currently use BURG boot loader to load up all the systems. However, BURG does not work with windows(I still manage) and it is a little finicky. So, I want to make windows work and have all the other OSes I want all on one boot loader. I already tried easy BCD and for whatever reason Fedora took over and blocked out the other OSes.

  • Subversion hard disk full

    - by user37914
    Our SVN server hd was full. Deleted a load of unwanted data on there, and all appeared to be well. However, new check-ins are now failing. Can't move '/repos/db/txn-protorevs/1000-vr.rev' to '/repos/db/revs/1/1001': Permission denied 1000-vr.rev does not exist. There are two other files in there: 9-9.rev and 9-9.rev-lock Edit: I have checked file permissions just in case, and all is as it should be.

  • Find out how many memory my server would need ideally?

    - by Daniel
    I have a pretty busy GNU/Linux server that I think needs more RAM. I know that the free command doesn't show the amount of RAM that is used. So I was stumbling upon Commited_As in /proc/meminfo. It currently shows 57972 kB which isn't much. Is this the amount of RAM that the processes use "right now" or is this an estimate of how many additional RAM it would take to never run out of memory with this load?

  • adding response header to Jetty config file

    - by Sam007
    I am trying to add a response header to the Jetty configuration the following command, Access-Control-Allow-Origin: * Ok so this Jetty webserver is the base on which Geoserver is running. I asked this question in the GIS forum but no one was able to answer it so I felt I might get the answer here. I wish to add this response to the header to remove the error Unable to load XMLHttpRequest I wish to know that under which tags should I wrap this response header and where in the file should I save it.

  • Lightweight ad-blocker for firefox

    - by student
    On a old machine (512 MB RAM) I am currently running ubuntu jaunty and firefox 3.0.15. I tried the ad blocker addon add block plus but it eats lots of RAM (300 MB). Is high memory load of this add-on a bug, which is fixed in a newer version or just normal? If so, why is the memory usage so high? Is there another ad blocker add-on for firefox or another browser- add-on combination for linux (ubuntu jaunty) which uses significant less RAM?

  • What kind of hosting is used for *tube sites?

    - by playcat
    Hello, When a site grows from a just-a-fun project to a site with bigger load of visitor, and you want to enable them to upload videos, you might find yourself in a need of a better hosting, including dedicated server and a no-limit web traffic (or some reasonable limit). So, if people can upload their videos, and if page has around 1000-10000 visitors per day, what kind of hosting is there to choose from? What is needed in that case? Thx

  • How to turn iptables stateless?

    - by tex
    Hi, I'm running a Linux server that - from time to time - faces heavy load and the conntrack table overflows. Since it's iptables firewall ruleset is very simple I'd like to turn it to stateless mode. I know that iptables can operate in stateful connection tracking mode and in a stateless mode. My firewall rules are all in place I'm pretty sure that they are stateless but my question is how can I verify that the firewall is really operating in stateless mode?

  • How can a cloud be created from virtualization or how is it different from virtualization?

    - by Echelon
    I have heard that virtualization is the basis of Cloud,so If i have a machine with xen as virtualizing environment and many vms running on it,then can that be called as a cloud. Is it true that vms that scale based on load and memory is called cloud and vms that do not scale is called as just virtualization! How can a vm scale??Based on my understanding for xen once we fix cpu and ram,it cant go beyond that (am aware of Dynamic memory Management) so how it really scale?.Can any one please clarify this

  • IIS6 - Classic ASP - "out of memory"/"out of string space"

    - by glaucon
    We have a classic ASP application that's under significantly more load than usual. We are from time to time been getting "out of memory" and "out of string space" in the httperr. We do not usually see these errors. For the moment we cannot change the application. Is there anything we can do to the IIS config which will help to reduce or stop these errors occurring ? The application pool is set to default values currently.

  • Is the XP VMM a bottleneck on a multi core machine?

    - by JeffV
    I have a dual Xeon hex core machine running an IO intensive application. (WinXP 32) I am seeing a hardware driver (1/2 user mode, 1/2 kernel, streaming data) that is using 6k delta page faults per second. When other applications load or allocate large amounts of memory the driver's hardware buffer gets an underrun (application not feeding it fast enough). Could this be because the kernel is only using one core to service page fault interrupts?

  • Is there a way to snapshot a running process to disk to restore it later?

    - by Sijin
    I usually work with a lot of instances of visual studio open to different projects, I was wondering if there is a way to snapshot/hibernate a running process to disk instead of closing it so that I can open it in the same state as it was quickly. I have a ton of free disk space so wouldn't mind saving the entire process snapshot if it would save me the time in opening up the solution and waiting for the projects to load.

  • Is data transfer response related to cable bandwidth limit?

    - by John Paku
    Hello, Before this, I'm using shared 100Mbps bandwidth. Its fast enough. And now, the server running dedicated 10Mbps bandwidth. When running 10Mbps, it takes more time to completely load the same page. The server bandwidth usage is small, with average less than 5Mbps. (I can see some website hosted at same data center loads very fast.)
