Network Lockup Issue Delays Sleep

[MoparShaha]

For the past few weeks, my PB sometimes takes up to 30 seconds to go to sleep when I close the lid. The problem is intermittent. I've repaired permissions, run the daily/weekly/monthly scripts, and flushed lookupd's cache. The problem also happens regardless of whether I have an active network connection before sleep. I have a screenshot of the console error log that shows the problem. My question is, what does this mean, and how do I fix it? Thanks.

I ran through my system.log and noticed that I am receiving the same error messages, though I do have an iMac, I don't have the sleep problem nor any negative effects that I could see. I did some searching and it seems this problem with lookupd is common with VPN's along with high latency for some reason in Tiger, though I haven't heard of it affecting your sleep mode. I did some testing and it seems that if I turn off my airport card in my Mac, lookupd stops hangup and resets, oddly though when I turned it back on I got the lookupd abnormal hangup again.

I'm still looking into it a bit more to see if there is a way to stop the hangups all together, but let me know if turning off airport before sleeping it, helps with the sleep problem at all.

tag, thanks for your help. You're right, when I turn AirPort off, I don't get that error message in the system.log file anymore, but my machine still has the sleeping problem. I don't notice any abnormal references in the console.log and system.log files, so I'm completely at a loss as to why this is happening. Also, I don't have any peripherals connected when this problem occurs, so I don't think it's the system waiting for another device, ect.

edit: Well, I created a new user and the sleep problem doesn't occur, so it must be something with my account. Also, when I logged back into my account, the problem was gone. So, I take it either something is specifically wrong with my account, or the problem eventually creeps up no matter what account is logged on.

I might just do a clean install again when 10.4.2 is released.

Well, hopefully your problem is fixed then (crosses fingers), anyways though, I did find this old apple article entitled "Mac OS X 10.2: Sleep Is Delayed When You Close a PowerBook or iBook". Now even though this is for 10.2 perhaps its related somehow since the symptom is that There can be a delay of up to 30 seconds?

Just a thought, you could possibly keep a record of what programs you have running when you sleep and maybe after a while narrow down the culprit.

I also found this MacRumors post which a 30 second delay is talked about, but no real solution. So this must be at least a semi known problem.

Yeah, that's what I think I'll do. Thanks again for your help tag. That second link does seem to indicate that this might not be an isolated incident. In the meantime, I might just log out and back in every few days, as this seemingly fixes the issue.

Glad I could help.
