I almost never shut down my MacBook. Always send it into standby or hibernation only. Never encountered any issue like this. Do you get any error message in OSX' console? Any idea when this started?

Same here. I also didn't have the issue before, it started with r27258.

One more thing, it looks like the iTunes import doesn't finish, could it have to do with that? Although I did have THAT problem also before.

nothing in the console log, btw.

> it started with r27258.

Then we should CC Andy.

So you have to do a hard reboot every time you try to sleep your Mac while SC is running?!

Yes.

Ouch, but I can't reproduce.  I can sleep in the midst of a scan, and at any other time.  I have my Mac configured to sleep only, not the default of safe sleep.

I'll experiment with that later today. I use safe sleep, but I've got DeepSleep and can use that to try "simple" sleep.
Right now I don't want a re-boot, though.
Should I update SC first?

This is one for QA.

Joerg:  have you had a chance to try the later versions of SC 7.4 and changing sleep states on your Mac?

I've had a chance and actually I was about to file another bug against SC on Mac but I might as well use this one.

The current SC (I think it updated today, it reports r27844) is much worse in that it doesn't only hang up my Mac on standby but also during regular operation.

I can't say what EXACTLY the issue is, my guess would be access to the server through the web interface (not the web interface itself/rendering of the web IF) but it's just a guess.

Symptoms: After a while of use, when I have the Preference Pane and the Web UI open, the Mac becomes completely unresponsive.
The CPU load is actually not very high but still switching between windows is VERY slow (as in: two minutes to switch to another window) and generally, the System Preferences lock up.
Generally also other apps some times lock up (I think they simply don't get to the foreground enough) but they become responsive again.

I haven't found a way to get the system responsive again other than (hard) re-booting, I don't think I found all SC related processes.

Another Symptom is that I can't get ANY access to the server through a browser when this happens.

I guess something in the scheduling or the UI locks up since - as written above - CPU load is actually pretty low.

Sorry that I can't give you an exact way to reproduce this but I happens every time I use SC on my Mac within an hour or so (I usually don't run SC on the Mac).

System:
MAcBook Air
OSX 10.5.7
SC r27844
Player: Squeezeslave
iTunes integration disabled (scan stalls when it's activated)

I did already deactivate all 3rd party plugins.

Oh, another thing:
I do use a 3G mobile connection with my MBA (HSDPA) which sometimes has high latency, especially with bad connections. I've seen other applications lock up when trying internet communication and not getting the expected turnaround times.

Is it a memory leak?  Look for 'perl' in Activity Monitor.

You are right, the symptoms sound a lot like a memory leak.
And my MBA is also a little bit low on available swap space.

I tried to find perl in the activity monitor but didn't . It's always shown (folded) as a sub-process of something and the system was responding just too slow to search for it.
Will try again later and look out for it upfront.
Will also watch the memory usage of the Preference Pande widget since that's what's my candidate.

Assigning to Steven to follow up if more info becomes available

this is an administrative shuffle on priority fields to help make better judgment on the top end of the priority list. P4->P5, P3->P4, and P2->P3.

Re-Targeting bugs that did not make it into 7.4.0 release

I didn't see this with 7.5 and newer anymore.

Unassigned bugs cannot have a priority.
