In Console.app, in the System logging section, I'm seeing messages like this, at a rate of roughly one per second:

19:09:38 kernel: Warning: IOSurface 00000236 seed changed while owned by an accelerator 00000003: 00000304 -> 00000146

What is this, and can I make it stop? It's making it almost impossible to read anything else in the log.

From the Apple Developer Reference, IOSurface is an API being called that allow applications to move complex image decompression and draw logic into a separate process to enhance security.

Apps that share media utilize this API, such as Messages or QuickTime.

I've read that this issue can arise when using a VPN, but I can't seem to corroborate that at the moment.

  • I do use Screen Sharing to access another machine sometimes, but I get these messages even when it isn't running. – Ken Nov 13 '13 at 20:46
  • The obvious question is: if it is caused by an app doing something funny with a kernel call, is there a way to figure out what app made this kernel call? – Ken Nov 13 '13 at 20:47
