    Ive tried iplayer on 2 different PC,s downloads work ok some of the time but most of the time kserice uses so much CPU time even task manager becomes non responsive.

    Is Kservice trying to set up to many seeds?

    Any one else seen this?

    I had this when I first used iPlayer, as did a number of others. After a while it seemed to sort itself out though, and behave more normally.

    One thing I wondered might have caused it was that I started off by downloading a number of programmes at once, and I think it also downloads a couple of dozen of the little intro segments for each channel that are played first. Tracking 30 or so downloads at once might have been the cause. Or it might have been something else, but then after that I was never downloading more than a couple at any time, and the problems never happened again.

    Yeah, same prob.

    I've been using iPlayer for about a month now. Worked fine.
    A couple of days ago, computer went into ultra go slow.
    I found kservice.exe using 100% of he cpu and removed the process. I didn't at the time know what it did.
    This fixed the go slow but stopped iplayer.

    I tried to download a program. Didn't work. Re-registered, re-installed iPlyer but to no avail. Kservice kept coming back though.

    Did some googleing and it turns out kService is the kontiki (beeb iplayer) process.
    My deleting it stopped iPlayer working.

    Some googleing also showed that malware can hide behind the kService.exe and therefore go undetected.

    Does anyone have a fix?

    Don't panic!

    Be assured that this is nothing to do with malware. There is no malware in the iPlayer installation.

    The Kontiki client isn't tuned correctly for single core processors in the current iPlayer release.

    My spies tell me that you should expect a new version in the next week or so, with tweaks to alleviate this problem.

    Hi ch21ss,

    you're right on the button with your comments about the intro segments. There are about 15-20 of these "idents" in use at any one time, and they all get downloaded automatically the first time you use iPlayer.

    This can make it look like the thing has frozen for a while - on one of my test PCs it took 8 minutes to get these "idents", while on another it took only 4 minutes.

    If you start downloading a prog as soon as you set up the iPlayer Library, it REALLY slows it down for a while. It will recover to normal behaviour once all the "idents" have arrived.

    As far as multiple simultaneous downloads are concerned, 30 at one time is pretty extreme! From my own testing, I've settled on no more than 6 concurrent downloads as a good compromise, but the optimum will probably vary hugely at different times, depending on all kinds of variables.

    A lot of users seem to choose to select a week's worth of downloads in one go, and leave the PC going overnight for one night to grab them all; this works well for many people.

    Thanks for all your feedback,

    I dont think it is the idents as they have arrived, I only have 4 downloads in progress.

    Both PCs are single core, one being only 999MHz

    I still get the same problem after I download a lot of programmes together.

    I hit "Ctrl+Alt+Del", end the kService in Task Manager "Processes", and restart my computer.

    A lengthy procedure, I know, but at the moment it seems to sort the problem.

    Same problem here.
    After using Iplayer without problems for several weeks, I tried to download 5 programs at once and since then I get Kservice using 100% cpu .
    Have tried removing Iplayer and reinstalling, doing a system restore from a week ago and even reloading the original Iplayer software, but stll 100% cpu when kservice starts up.
    Obviously something is not being removed when I use program remove - ??

    After reading this thread I checked with Task Manager, at the moment I am downloading 3 programs but my CPU usage is only between 3% and 8% I am not very technically minded so could anybody tell me which factors would affect CPU usage.
    Thanks

    If you are having problems with KService hogging system resources, you can use a program called BES to limit the priority of the application.

    You can download it from here

    mion.faireal.net/BES/

    Just open the app (no need to install, it's a standalone), click Target, scroll down to find KService, click Limit This, choose Yes to agree.

    Close the list of apps then click the Control button, and just play around with that. I would put it at about "-60%".

    I wrote this down because the thread priority thing in Task Manager doesn't work, it comes up with an error.

    This program has saved me AGES of time waiting because I had major problems with 4oD doing downloads as well, and it made the system hang like every 3 minutes, but with this, when it hangs, it sets the max resource to what you like, so you don't have to wait around.

    Enjoy smiley - smiley

    I've tried this programme but it keeps on saying that it has failed to limit KService, so I end up having to end KService through Task Manager. How on earth has this awful Kontiki software managed to gain so many big customers (Channel 4, BBC, Sky Anytime)?

    Lol; I find the iPlayer luvvies so amusing?

    Not malware?

    en.wikipedia.org/wik...

    "Malware is software designed to infiltrate or damage a computer system without the owner's informed consent."

    Kontiki does 'infiltrate' your PC - without your consent, it consumes all of your PC's resources, consumes your internet bandwidth and - to cap it all - it expressly states in the iPlayer Ts&Cs that your machine can be remotely inspected and the software remotely updated WITHOUT YOUR CONSENT.

    Now, that's what I call malware.

    If BES says it has failed, try the Limit/Watch button instead of just Limit.

    Make sure you are running as administrator.

    If that doesn't help, check the website URL for more help.

    I hope you can get it working, it really does help.

    I'm not a fan of Kontiki, but I am a fan of taking responsibility for your own actions on your own machine when you install software.

    You say that Kontiki has no consent to behave as it does, but when you install this software, you are shown the EULA and the Ts & Cs for iPlayer/Kontiki. They make it quite plain that you are consenting to participate in a form of P2P file sharing which leverages upload capacity even when downloads are not in flight, unless you use the built in preference setting to stop this from happening.

    When you choose to proceed you are expressly giving your consent.

    RTFM

    The fact that it is currently poorly configured for single core processors is a separate matter. This is something which needs to be addressed by the vendor, but it does not make the software malware, any more than a bad Linux distro installer is malware. It's just software that needs some more work done on it.

    I'm afraid clicking Limit/Watch only crashed BES. I've hate to uninstall 4oD and iPlayer once again. Someone really needs to get this sorted out.

    I'm sorry to hear that BES didn't solve your problem. That's just... ggrrr...

    Anyway, thanks for posting your messages and trying it out, I'm sorry I couldn't help you smiley - sadface

    I doubt this problem will get solved, though. The Kontiki service will do this no matter what broadcaster you are using - be it BBC, 4oD or Sky. It will soak up the CPU due to the nature of the program, being a P2P sharing app. Unless the Kontiki provider gets paid to change their application, I doubt there will be a solution smiley - sadface

    I do wish people wouldn't post their assumptions as if they were statements of fact.

    "Soaking up CPU due to the nature of the program (sic)" and "being a P2P sharing app" is a non-sequitur; the two are not synonymous.

    Kontiki ships with a full blown SDK - there are a multitude of tweaks available to the deployer - and is also subject to an active ongoing development stream within Verisign. There is NO reason to "doubt there will be a solution".

    I'm not an apologist for Kontiki, I'm just asking for informed debate rather than drivel.
