Hi,
Recently I've had an issue with my Macbook Pro running mountain lion. While running chrome or preview, these are the only two programs so far that I've experienced it with, a random lag spike will hit freezing all windows and giving me the rainbow wheel for about 60 seconds. While this occurs, the activity monitor usually shows Google chrome with about %18 activity but Image Capture Extension spikes up to about %40-60 locking any other CPU process I have available. After the computer goes back to normal the console usually has multiple entries from Google Chrome or Preview stating something like this:
4/21/13 11:03:14.661 PM Google Chrome[42411]:
***** Failed to send command [async]: {
ICACommandKey = ICARegisterForEventNotificationCmd;
ICAEventsOfInterestKey = (
ICANotificationTypeDeviceRemoved,
ICANotificationTypeDeviceStatusInfo,
ICANotificationTypeScanProgressStatus,
ICANotificationTypeScannerOverviewOverlayAvailable,
ICANotificationTypeDeviceStatusError,
ICANotificationTypeScannerButtonPressed,
ICANotificationTypeScannerPageDone,
ICANotificationTypeScannerScanDone,
ICANotificationTypeScannerSessionClosed,
ICANotificationTypeTransactionCanceled,
ICANotificationTypeObjectAdded
);
ICAExecutableArchitectureKey = 7;
ICANotificationProcKey = 0;
ICAObjectOfInterestKey = 0;
ICARefconKey = 2139422048;
ICC = Y;
} [loc:1]
This example is an error from Chrome but the Preview one has a similar format stating an error with async. I'm not new to computers in any sense but this is the first thing I've ever seen of this sort and I haven't been able to find anyone else with the problem. If anyone has any advice that would be much appreciated because as a student studying Computer Science, I need my computer. Thanks!
