Mail.app Killing CPU Usage

hmmm...well (null) is back down to 0% of the CPU and mail is still up at 70% or more, and mail just gained another thread. i'm not really worried about this, just curious as to what's causing it :confused:

Edit: well (null) just went up to 10% and back down to 0% over the course of the last ten minutes, mail finally went back to 0%. looks like everything is back to normal except for (null). if anyone has any insight then feel free to let me know :)
 
well.. for almost an hour now mine has been fine. but the whole thing still bothers me and the fact that others are experiencing the same is troubling. I am hoping that Monday morning with fresh new faces that are smarter then me can figure it out. But, I do think this will be a HUGE ripple in the mac community.
 
I still haven't seen any of these problems. My Mail.app still hovers around 0% CPU wen idle, showing 7 threads.

I have to believe this is some sort of background indexing, cleanup, or compacting task. In Mail Preferences you can tell it when to move messages to the trash, delete them, and delete Junk Mail messages based on how old the messages are. Maybe it had something to do with that. Most of mine are set to 'Never' since I clean up manually once in a while.

Any thoughts?
 
I experienced this problem yesterday. It seems to be fixed now, though. I have a total of 11 messages in my inbox so I don't think background indexing or cleanup are causing the problem.
 
Someone sent me a picture yesterday that was a JPEG of the strange type that many programs won't open. Mail displayed it in the preview window, but then it started spinning. I leave AM on all the time with the cpu gauge in the dock. It takes hardly any CPU cycles if you turn the "update frequency" to 5 seconds. This is the update for all processes, not just CPU usage. For some stupid reason apple likes it to run even when the window is closed. The CPU speed icon still updates at 1 hz, though.

Deleting that mail and restarting mail.app fixed it. just restarting without deleting fixed it, but as soon as I clicked another email and then came back to that one, it spun again.

i also experienced this problem yesterday (Halloween) and today it is back to its old self. the weird thing is that when it was using all the cpu i opened the activity viewer in mail and the network traffic tab in activity monitor and there weren't any connections that mail was trying to make. i looked at the disk activity and it was also doing nothing so no indexing the messages.
also, i have not installed the security update yet, only the qt and itunes
this problem is really odd effecting so many on the same day but the next day its back to normal
 
it would seem that all is well with mail in the world, but why last night on Halloween (i think the holiday has nothing to do with the bizarre events) did so many people experience this? I think many more people experienced this issue and did not realize it (as a menumeter like app was not running). I didn't see severe loss in cpu power other then what was displayed in the menubar. It started sometime around midnight and continued until about 2-3 am i'd say.I see this as weird. Weird that so many people had the same issues and as quickly and random as it came, it vanished. Could it have been some sort of indexing? could it have been something to do with the time change? Is there anyone out there with some answers?
 
Maybe there are a significant number of mail servers that adjusted their time. This usually happens about 1-2 in the morning doesn't it?

There could be some strange repercussions with gaining that hour from nowhere. :confused:

Click to expand...

the time change happened 21 hours before the problems started for me. everything seems to be back to normal now though besides (null) whatever that is :confused:

It's been working fine for me too, but I noticed that previously I had Mail checking for mail every 5 minutes, but somehow that was set to Manually... not sure how that happened.
 
ok, it seems like everything is back to normal for everyone, but in my case even though mail fixed itself, now (null) is taking up 80+% of the CPU. as far as i can tell its not doing anything :confused: if anyone has any idea what's going on, let me know. im getting curious now :p
