Resolved Why is my 1,1 Mac Pro taking several seconds to fall asleep?

[PowerMac G4 MDD]

Hi everyone,

So I have here a 1,1 Mac Pro that's running 10.8.3 Mountain Lion. In the past, I noticed that it was taking around 20 seconds just to fall asleep (after choosing Apple > Sleep). When that happened, I was thinking that my sharing preferences were possibly interfering with it and causing a delay before sleep. I turned off all sharing for my computer (and turned off 'Wake for Internet Access,' and what not), and it began going to sleep instantly again...

However, this problem has come back, and this time, my sharing prefs are already off, there are no documents sitting in my printer queue, and I close all applications before pressing 'Sleep.' This time, I am confused as to what is causing this thing to take forever to fall asleep.

It could be an intermittent problem, due to my three internal HDDs and one external, but it seems as though they aren't processing info before sleeping (as I don't hear them thumping). I noticed, though, that in MenuMeters, I see a little bit of network activity while it is going to sleep... I am wondering if this is the culprit, but I am not sure. I just got MenuMeters recently, so I cannot say whether or not this network activity was present even while the computer WAS still able to sleep just fine. I have no idea where this network activity is coming from, or whether or not it's even an issue.

Would anyone know the problem? NO, I do not have open printer queues, and NO, I don't have stray applications open.

Thanks,

-MDD

EDIT: I found out that my external iSight camera was causing this to happen. I simply unplugged it, and now the computer goes to sleep instantly. Maybe just some weird iChat/iSight prefs or something like that. If not, I don't exactly know why the camera was causing this--note that I leave my camera's lens closed.

Wish I could be of help, but my 1,1 Mac Pro hasn't gone to sleep properly since the main board was replaced under warranty back in 2006.....
It also takes a few seconds to sleep, but the worst part is none of my optical drives are seen after it wakes up - if it wakes up that is. I have it set to never sleep to avoid these problems.

Wow, that's very unfortunate. That thing also uses lots of power; you should calculate how much it's costing you to run it - it may not even be worth it.

Jeez my hackintosh sleeps and your MP doesn't...

If I safe boot it I can get it to sleep. Still lose my Blu-ray drive when it wakes up though. Have to go through my system to see if I can find the problem one of these days.

Found the culprit! It was the old SIIG PCIe single port RS-232 card. I forgot it was even still in the machine. It has been so long I forgot what I got the card for in the first place, LOL.
