A few days ago, iTunes started "skipping" while I listened to music: a brief interruption of the music, almost immediately resumed as if nothing has happened.

It seems to coincide with clicking the mouse button in another app while iTunes is playing in the background.

Anyone know what might be causing this?

Thanks!

I have had the same problem on my windows2000 machine running itunes. I run a large cad software package and figure it was just a memory issue. Sorry that this is not much help to you but I to would be interested in knowing if there is a solution.

Could just be iTunes hiccuping.

Sometimes when I plug the iPod in it stutters when it's updating it.. I get annoying and then I realize that it was my doing..

It IS hiccuping, but that doesn't make it acceptable.

It hasn't hiccuped for me ever before...

Yeah I am having this same issue on my 1Ghz 17" iMac w/ 512 ram running 10.3.2 w/ the newest iTunes.
I also notice that it is when iTunes is playing in the background.

I haven't had that happen for quite a while now, but it sure used to. But at least we can be thankful that the music doesn't hiccup when we start a dial-up connection to the Internet, as is usually the case in Windows .

iTunes skips badly when the system is paging out. That would account for it happening when switching to another app, as one poster mentioned. The solution: get more RAM.

I have 1G of RAM, and as I said, it never skipped until recently.

Also, it happens even when I'm clicking on a card in a solitaire game: no other apps loaded or opening.

No: this is a problem within iTunes or Panther. Getting more RAM is a good idea in general, but no one should do it just to solve this problem.

sudo renice -5 [PIDofiTunes]

Or download a GUI front-end and do it that way...

Nicer is the front-end that I wrote/use. It's freeware but I haven't been actively developing it so you may want to search for something newer.

That should ensure that it gets plenty of CPU time, anyway.

I had the stuttering only a couple of days ago. I was using a very large RAM-intensive appliation. No matter which app I used, just moving the mouse around would cause iTunes to stutter.

Quitting and restarted the memory hog fixed it, and the stuttering has been gone ever since.

No app was hogging the CPU.

(1GB RAM installed too.)

This has been happening to me (again) almost constantly for the past few days. FWIW, I have 512 MB of RAM, and this also never happened under 10.2.6 (yes, maybe I should update to Panther, but I am laziness incarnate).

I have the stuttering on both my iBook G4 and my Cube with 1gig of RAM and Powerlogix 1GHz. It seem to be a problem with Panther and not iTunes specific. Also Safari stutters and Finder as well. It happens about every 2 minutes, but sometimes more frequently. The "pause" lasts for about 2 seconds every time. I have tried to monitor with top and other monitors without identifying the culprit. Here is to hoping for 10.3.3 to fix the problem.

Turning off iTunes sharing on both machines seems to have cured the stutters. Have tested for about two hours without any slowdowns in any app. Just my two cents. Let me know if this works for anyone else...


EDIT: Have tested for several more hours without any hiccups or short freezes. Seems that the sharing feature of iTunes runs some sort of deamon checking the network for other shared librarys since the stuttering happened also when iTunes was not running. I guess it was some sort of check/polling that the made the OS freeze completely for about 2 seconds. This seems to happen only with the last two versions of iTunes (never had it before upgrading iTunes). Pretty sure this was the root of my problems. Glad itīs solved because it was extremely annoying. Give it a try if you have the stuttring symptoms.

I have iTunes Music Sharing off, and it still happens to me. I'm also not running Panther.

(It's time for a new computer, anyway...)
