Mail goes to 100% CPU and becomes unresponsive on one e-mail

Until this morning, I've had no problems with Mail. A business associate sent me an e-mail as a reply to a conversation spanning several weeks with a small PDF attachment. When I went to read the e-mail on my MacBook Pro, Mail became unresponsive with the "loading panel" twirling in the e-mail pane. CPU load went to 100% and remained there. I found that if I clicked on another mailbox, eventually (minutes later) it would become selected and CPU load would drop back down to normal. Tried it several times with the same results.
My mail server filters out spam and forwards all e-mails to my gmail account so that I have all of my e-mails on my iPhone. I found the offending e-mail on my iPhone and found that it opened just fine and the attachment opened fine too. Thinking that the e-mail had somehow become corrupted, I deleted it from my MacBook Pro then forwarded the message from my iPhone to the account used by my MacBook Pro. When I went to read the forwarded e-mail on my MBP, the same problem occurred. From what I can see in my iPhone there's nothing unusual about the e-mail, just some text and the small PDF attachment. I can open other e-mails with PDF attachments fine. It's just this one e-mail that gives Mail a problem.
Here's what I've done so far:
Using Disk Utility, I did a repair on my MBP volume - no problems found.
I did a permissions repair - nothing unusual.
I did a rebuild on all of my mail folders - everything went okay.
I disabled and uninstalled Letter Opener Pro (the only plug-in I use with Mail)
I disabled Norton.
Still no joy. I realize I can just delete the e-mail and go on with life but ideally I would like to be able to solve the problem so it doesn't happen again. Has anyone else had this problem and if so, how did you solve it?

Safari has been known to cause cpu usage to spike. If nothing else, report the pages to Apple using "Report Bugs to Apple" under the Safari menu.
One of the Safari issues in the OS X 10.4.4 update was:
Addresses an issue in which some websites, such as www.cbsnews.com, could cause CPU usage to spike unnecessarily, or cause Safari to stop responding, unless Safari's Enable JavaScript preference was deselected.
It is possible that they didn't get it completely fixed.
I have also noticed that Safari slows down after being open for an extended period or if I have tons of tabs open, although it is not as bad as it once was. Additionally, regardless of anything else, it does appear that some sites slow down Safari's performance and/or spike the cpu usage until I close that tab. (I've had this happen to me with Firefox as well, by the way).

Safari goes to 100% CPU and stays there on certain websites

I got a new computer a month or two ago (a Powerbook 1.67), and used apple's migration assistant to transfer all my stuff over from that comp to this one. Ever since I've started using the comp, when I use safari to load certain pages or parts of pages, such as www.mapquest.com (when I try to type in the directions from/to box, or try to load recent searches) or www.orbitz.com (any time I'm on the results screen once I've searched for a flight or some such), the CPU load goes to 100%, and stays there until I close the tab with that site in it (even with safari in the background), and anything else I try to do until the tab is closed runs like molasses. This definitely did not ever happen with my old Powerbook 867, but I don't recall installing any new safari extensions or plug-ins since I got the new computer, so I'm somewhat mystified as to what is causing it. Do you guys have any thoughts as to what it might be, or suggestions as to how best to go about figuring it out?
Thanks for any help you can provide.

Install itunes - cpu goes to 100 percent and stalls. Uninstalled, tried fixes on internet, reinstalled - same story

Have installed, uninstalled itunes on xp machine and tried all the fixes given in the discussion groups, plus cnet and other internet fixes.....nothing works. After installation of itunes cpu usage goes to 100 percent and itunes stops. Cpu stays at 100 percent until I uninstall itunes. By the number of posts on the internet, I can't believe Apple hasn't addressed this issue with a fix.

I had the same problem but this worked for me.
Get to a dos command prompt and type: netsh winsock reset
You will need to reboot your computer but it fixed tocpu 100% issue.
Good luck

Keychain goes to 100% CPU

Has anyone seen a problem where keychain goes into 100% CPU mode for a while? During this period, it's generally unresponsive. What seems to trigger it is editting an existing password: I can erase a character or two, but then at some point, it just goes wild. It does recover eventually (a couple of minutes); a Quit fails, but a Force Quit works, after which it comes back up with no problems (though re-trying the change often triggers the problem again). Quite annoying.
I'm seeing this under 10.4.10, though it was there in several earlier 10.4.x releases. (I'm not sure how long, but I recall looking at several setsw of release notes to see if a fix was reported.) This is on a PowerPC.

SQL Causes server to swap and become unresponsive, What is it doing?

SQL Causes server to swap and become unresponsive does it have the same effect with other users??
WARNING - script causes my servers to not respond, requiring reboot after 30 mins
Only run on a server/vm where a bounce is ok
The script creates a table
Runs an anonymous block to put 160mb in a single clob
Runs a simple select with some REGEXP_REPLACE and REGEXP_SUBSTR
This has been raised with Oracle support.
Their conclusion is lots of single block reads are causing the server to hang.
I do not think this is the reason and would like someone else to run it, to see what they think!

Now I am lost!!
As Iggy points out from the strace, the OS is returning an error back to the Oracle foreground process, is this not handled?
Or is it normal for oracle to ignore this error, and ask for more memory?
Any help would be greatly appreciated.
Thanks,

MacBook Pro Retina Black Screens and Becomes Unresponsive

I've been having issues with my laptop where all of a sudden it would black screen and become unresponsive. Checking the console messages I see a lot of records referring to "AppleVTD: waiting space". This seems to be a reoccuring problem. I've already repaired my disk once and now it's happening again, I've ran the disk utility and it is telling me that my hard drive needs repairs again.
Here is an extract from the console messages from today:

I got about a hundred lines within that same error within that second
Witin the next 2 minutes I was able to reboot and it is running, for now. I'll be doing another round of disk repair, but this isn't sustainable. Can anybody elp me in identifying the root cause of these issues?
Thanks in advance,
Svetlana

and then my entire system freezes. This has been happening at least once daily, and it's killing my productivity.
Have you figured out what was going on?
And, are you running any virtualization software, like Parallels?
Anyone out there know what's going on? I'm pretty desperate here...
Thanks so much!

System completely freezes and becomes unresponsive

Hi,
We have a single processor, 1 GB RAM Redhat system (desktop). Normally with the database(oracle 10.1g) and client connections running, the memory utilization of this server is around 90-99% . However every few days the box completely freezes and becomes unresponsive (users cannot login, client connections fail). We have to hardboot the box and restart the database. When in stuck state, the log files are not updated, except that sendmail logs heavy load average. ( Messages like "Load Avg 12: 1 Times(s) Load Avg 13: 1 Times(s) Load Avg 14: 1 Times" and so on) and the free memory falls to 8 mb or less but with above 2 gb swap space available.
My question is if there is no free memory, system should thrash (excessive swapping) and become slow, but instead our box completely freezes, though the interactive response ( for any connection which is still active) and ping response is ok, they aren't slow.
Is there any kernel level parameter that can be tuned so the server won't freeze, (tries to move the memory pages to swap space or any other way). When the server is stuck (freezes ) any ssh connections still active will stay on, but new connections fail. One time, using that session, I tried to free up memory by killing processes like X Server etc, but still the server didn't unfreeze.
Server info:
Red Hat Enterprise Linux AS release 3 (Taroon Update 4)
Kernel (uname -r) 2.4.21-27.EL
Intel Pentium 4 CPU 2.80GHz (Single processor)
1 GB RAM
Oracle db version - 10.1.0.3.0
Lastly, I don't think this is any hw problem, because we see similiar problem on multiple system with similiar configs.
Please guide how to resolve the problem. Thanks.

Please launch the Console application and select "system.log" from the file list. Enter "mDNSResponder" (without the quotes) in the search field. Post a sample of the log messages in the Console window -- only one example of each repeated message, please.

ITunes freezes and becomes unresponsive when I plug in my iPad.

I have Windows 7, and iTunes works perfectly fine, until I plug in my iPad or any device (I have a iPod touch 4 generation and iPhone 4s). The second I plug in my iPad, iTunes completely freezes and becomes unresponsive. It also becomes unresponsive when I try to go to Preferences. I have to go to task manager to force iTunes to close, but if I unplugged my iPad, iTunes becomes responsive after a couple minutes.
I have researched this problem multiple times, and it seems several others are experiencing the same problem. I have tried their suggested advice, and it did not work for me. I have tried many methods to solving the solution, but it freezes up so quickly I can't even access my iPad on iTunes to ensure that it won't sync automatically. I have also tried holding Ctrl+Shift when plugging it in because iTunes said that way it won't sync automatically. This, however, does not work. iTunes is beginning to become very frustrating. I just really need any advice that will allow me to sync my device ASAP.
I understand there must be some sort of bug in the latest version of iTunes (I also have the latest version of iOS on my iPad and iPhone), but if anyone has any advice as to how to get around this, it would be greatly appreciated. Thank you.

JDK1.3: 100% CPU and total hanging up

Our environemt is HP-UX with 4 CPU, 2.5Gb of memory. Java is 1.3.13 (latest release). All necessary Unix patches installed.
We perform a load test over our application server with 40 users only. The test is pretty simple and doesn't deserve to be explained here (it uses no special system resources). In an unpredictable moment the java process utilizes 100% CPU and doesn't react to 'kill -3' but to 'kill -9' only. The problem is it happens whenever it wishes. No logic behind it. Every test loop takes about 1 minute to complete and the server gets stucked sometimes after 10 mins and sometimes after 3 houres of work. Changing java heap parameters and playing with new/old generation ratio also doesn't lead to any conclusion. Sometimes it happens before full gc but other settings allow full gc to happen every minute and the server works for hours.
What can it be? Any ideas? Any directions of investingation the problem?

What can it be? Any ideas? Any directions of investingation the problem?An endless do-nothing loop. I've seen HotSpot optimize such a loop to a single "jump-to-self" CPU instruction. HotSpot doesn't know how to insert a suspension safepoint into a loop that consists of a single instruction. When GC next kicks in it suspends every thread (including the signal dispatcher, which is responsible for a thread dump) but the nop-loop thread continues with free reign of the CPU.
In my case the loop looked like the following. A thread is started running this class, later another thread passes it some data by calling put(). There is no synchronization so the former thread is not obliged to see the effects of any other thread. The optimizer legally considered this loop to be do-nothing.
class ... implements Runnable {
    private Object data;
    public void put(Object data) {
        this.data = data;
    public void run() {
        while (true) {
            if (data == null) continue;
            // process data
}Since you can't get a thread dump it's very hard to pinpoint the problematic piece of code (unless you have Sun's poprietary tools that restore Java state from a core file).
If your code base is reasonably small, review it thoroughly for what can be an endless do-nothing loop. Another approach is to incrementally insert System.err.println("") into suspicious loops. This will add a call to native code and thus a suspension safepoint. Once you no longer can reproduce the problem, you must have hit the problemmatic loop. Go back and review it carefully.

CF4.5 uses 100% CPU and hangs

Hello,
According to the ColdFusion Forums my problem is not a new one but I still want
to post it with the hope to get some kind of answer.
I'm are running the following system:
CF 4.5 Enterprise Server
SiteMinder 6.0
IIS 5.0
MS SqlServer 2005
Both the CF and database server are Win2000 SP4.
About every one hours the CF server uses 100% CPU and from than on it is
impossible to log into the application. The site is still available though.
After restarting the CF service everything works fine until.....
I do not know what triggers this but I suspect it has something to do with
SiteMinder and logging onto the application.
The site has to go live on Monday so you can imagine the pressure to get
this fixed before the weekend.
Greetings,
Jilani

Jilani, you mention that this seems connected to SiteMinder. Do you mean you have your own version of SiteMinder, separate from the built-in one that came with CF 4 and 5? I wonder if there could be a conflict between them. Why are you using the full SiteMinder? And do you really need it?
More curious is that you say this spike happens every hour. Can you confirm if it's every 67 minutes, specifically? If so, then I would assert that this could be a problem related to the client variable purge process, which I discuss here:
http://www.carehart.org/blog/client/index.cfm/2006/10/4/bots_and_spiders_and_poor_CF_perfo rmance
But that may not be the issue if simply enabling/disabling the siteminder service will immediately recreate your problem....unless somehow the DB used by SiteMinder is the same DB used for client variables. Do you have any datasources listed in the CF Admin page for client variables? Any chance there's a connection between them and siteminder?
/charlie
PS This whole issue of client variables and how they can hurt you unexpectedly is something I'll dicuss this Thursday at noon US EDT, when I present "Clients and Sessions and Crashes, Oh My", to the online ColdFusion Meetup: www.coldfusionmeeetup.com.

Macbook Pro 13-inch (10.6.8) random white/black screens and becomes unresponsive...what is wrong/what to do to solve?

PLEASE PLEASE READ THIS I'M IN NEED OF URGENT HELP. || Heeey everyone! I'm new here. Please don't bite me. =))
Okay. So I have a Macbook Pro, 13 inch (bought Dec. 2010). It's currently running on Snow Leopard (10.6.8). It had a hard drive crash in Feb. 2012...I had it replaced and lost all my files . It had two major falls (January 2011 & November 2012). Oh, and it also makes this weird grinding noise when you listen closely.
Everything was going fine, until last week, I encountered a kernel panic. Restarted, but was faced with that awkward blank white screen thing at start up. I was told at the Apple Store back when my hard drive crashed in Feb. 2012 that repeated pressing down of the power button can be damaging, so I waited for it to run out of battery to restart. After that, it was normal again. I downloaded OnyX and verified/repaired permissions...nothing was out of the ordinary.
THEN. The next day, in the middle of use, my mac suddenly black-screened. Not a lot of windows were open, and I wasn't doing anything that...will put a strain on anything. It wasn't total pitch-black like the screen looks like when it's turned off. I could still hear the hard drive working and making that grinding sound. I pressed the caps-lock key, and it didn't light up. =))) What, is it off or something? But I can still hear the hard drive there. And it's totally unresponsive. So I decided to restart by pressing down the power button. It was normal again...until a few hours later when it suddenly white-screened. OKAY it's white now. I don't know what that's supposed to mean. But it had the same symptoms as the black-screen. Unresponsive, caps-lock didn't light up, normal grinding sound as if the computer was still on. So I let it run out of battery so I could restart. Upon restarting, I opened Disk Utility and verified disk permissions. There was no damage, nothing again.
I recently got uTorrent (around late December), and thought that it might have been that, so I deleted it and emptied trash. The next day, it did the black screen again. Same with the next day. There's at least one per day. It didn't seem to affect performance at all, everything still ran smoothly. I made sure to check disk permissions to see if everything was okay. And everything was.
Then, about three days passed without any black/white screen and I thought that nuisance was over. BUT NO. Two days ago, I got black-white-white screened and I was...shocked. I let it run out of battery again. =))) Checked Disk Utility, again, nothing. So I decided to get that Software Update thingo that always pops up. I upgraded to 10.6.8. A day passed without the dreaded black/white screens. But yesterday, it white screened once. And today, it white screened again.
I really can't figure out a concrete pattern. It seems random. But what I do know is that:
1. It happens in the afternoon. All the time, consistently in the afternoon. LOOOL IDK what this is supposed to mean, but its one of the common factors. =))
2. Most of the time, it happens when I leave the computer for about 30 seconds - 1 minute to get something. Or if I'm watching a long video (like a TV show episode), a period of time where I don't touch the mouse/press any keys. Is that related somehow?
3. I can't do anything to get it out of the white/black screen except restart. Each time I restart, I check Disk Utility and nothing is wrong.
And yes, I've went to the Apple Store to get this checked. All they said is: "Upgrade to Lion, maybe the error will disappear. If it does, then it was just a software error. If it doesn't...then sorry." LOOOOOOL NOT FALLING FOR THAT, not spending money when I'm not sure it'll fix the error. I want concrete answers.
I'm a student, and my Christmas Break will be over in less than a week. SO I NEED ALL THE HELP IN THE WORLD PLEASE. What is wrong with my laptop? Can I fix this? Will opening it in safe mode help in any way? PLEASE I'M DESPERATE.

Try these:
See what's loading in your login items. - delete the ones you don't need.
Open up Activity Monitor and under all processes, see what's using most of your cpu's resources. Highlight the ones using the most % CPU and hit quit process.
Next, open up disk utility and verify your disk. Once that's done, verify disk permissions - repair if needed.
Restart your Macbook and see if it speeds things up for you.
good luck....
