I hope you're reporting this to Apple as well? –  Steve Folly Oct 21 '09 at 22:27
    
Every time. It's been happening for a while now, since well before Snow Leopard was released. I'm imagining it has something to do with something unique about my system, the external drives or some faulty plugin or something. –  kubi Oct 21 '09 at 22:46
    
Have you tried removing any plugins, does it only occur with your user account? –  Chealion Oct 22 '09 at 1:13
    
Run Apple Hardware Test and/or memtest. –  Hasaan Chop Nov 22 '09 at 23:56

Are you reading any http net-radio or video streams using iTunes?

The _ZN14HTTPReadStream11streamEventEm function appears in the callstack shortly after __CFRunLoopDoSources0 is called. The latter probably examines the status of known streaming sources and subsequently calls the former upon noticing that there is indeed something worth streaming.

I can only assume that there are invalid data inside the stream which the streaming code doesn't handle properly, leading to an absurd memory allocation instead of ignoring the faulty data.

Try to notice which audio/video sources you are playing from when this bug appears. If you can pinpoint one that systematically causes it, you should then include its URL in your next Apple Crash Report.

Note that this crash implies up to two bugs in iTunes' code:

  • Failure to handle invalid data (this one is only probable).
  • Failure to properly handle Out Of Memory exceptions.

(and I'm pretty naive to reply to a one year old question, but well, you never know :) )

Get rid of SafariAdBlock and any other InputManagers you've thrown on your system. If you need help finding them, run this:

That wasn't it, either. The only input manager I had installed was AdBlock, removing it didn't help. Thanks, though. –  kubi Apr 11 '10 at 15:37
