IOHIDEventQueueEnqueue: Error enqueuing memory. (0xe00002e8)

Hi,

I've been having a weird problem where my machine freezes up for about 5-10 seconds, and then unsticks for about 3-6 seconds. This repeats until the machine either crashes or I reboot it.

I'm not sure if this problem will become a big issue or not - it has only occurred once so far, but I thought I'd mention it to see if anyone else has had this problem?

Same error here with a MacBook Pro that we just received yesterday.

exact error is as follows:
Apr 3 16:54:43 Macintosh HD /usr/libexec/hidd[36]: IOHIDEventQueueEnqueue: Error enqueuing memory. (0xe00002e8)

logs are filled with this.

login as single user and it spills into stdout making it hard to do things.

funn. seems this is limited to MBA and new MBPs?

I just had this problem again.

Right before the problem occurred, I was opening a XIB in interface builder from Xcode... IB seemed to take a bit longer than expected and then there were graphical anomalies with the IB windows - sort of black pixelated patterns all over the windows....

Also when I first got this machine, there was this crazy glitch where the whole screen became all sorts of different colors, kind of like a hippie dye tee-shirt. Stuff still worked, and I could reboot the computer, but I couldn't see anything - it was just one huge crazy glitch over the entire screen.

I wonder if there is some problems with the graphics driver, or perhaps the multi-touch pad.

Regards,
Samuel

I read about that too, but chose not to follow that advice..

syslogd is pretty important - it keeps track of everything that is going on in the system and logs it to /var/log - without syslogd you are really disabling your system as you can't really keep track of what is going on... for example, I'd guess that the information available via Console.app would disappear..

At any rate, this doesn't sound like much of a fix - more likely it is just removing the point of contention for logging the thousands of errors that are occurring. This really needs to be addressed by Apple, as far as I can tell...

Its really make me frustrated since this is a new laptop and it cost me a lot... do they even test their hardware+os before they start shipping??? This seems like a problem a lot of people are having so I am honestly really surprised that they haven't resolved it yet - these machines have been out for at least a few months.

I own a 2 weeks old Macbook Pro 2.4Ghz penryn and noticed some momentarily 3 seconds hanging from time to time. I inspected the system log and found the exact same error messages "IOHIDEventQueueEnqueue: Error enqueuing memory. (0xe00002e8)".
So it happens on MBA and on my new MBP 😟

I hope apple will fix this issue ASAP, or at least give us a clue whether this is a hardware problem or software. (Never had this issue on my 10.5.2 Macbook 2nd gen)
