MacPro and Excessive CPU usage

Still trying to figure out what is happening to my 2.66 MP.
At least once a day, for no apparent reason, the first core will all of a sudden go to 100% usage and despite what I close, it stays there. I close every app and even log out and log back in and it doesn't change. If I restart, the problem is gone.
I did run Migration Assistant from my old QS G4.
I am running 10.4.8 with 3 Ghz of RAM. I ran AHT and the system and RAM checks out fine. Even ran the new Universal Applejack. Problem still remains. It is so intermittent it is going to be impossible to troubleshoot. When it started today, I was noticed it after I started iTunes in that the audio would break-up. Any clues?

Happening Now this is from terminal

Yosemite and Mail massive memory leak and excessive CPU usage

I've just installed Yosemite and upgraded to 10.10.2 via the AppStore. Now I have a problem with Mail sucking up all the CPU (>106% !) and memory (>8Gb and rising while doing nothing). Everything runs fine when I quit Mail. Very disturbing behaviour!
I've tried several suggestions found elsewhere on the board here, such as turning off and even removing all Mail plug-ins including SpamSieve, but without positive results. I've tried un-selecting 'Store draft msgs on server', as well as the option for junk and sent msgs. but again without any difference. Going Offline within Mail also makes no difference to its memory hogging or CPU usage.
I notice this is an issue that's been around since last year (wish I'd known that before upgrading to Yosemite today) and I am just completely flabbergasted that it still exists. Would've thought Apple'd have fixed it in the first but certainly in the second incremental OSX Yosemite release.
Is there anything else I could try that's proven to be effective in stopping Mail's massive memory leak?

Okay, I've run Disk Util and restarted. Seems to have made a little bit of a difference to the RAM gobbling in that it appears to be going at a slower rate, but it's still up at around the 45Gb after an hour. Here's the EtreCheck report in the hope that it helps.

Slowness and excessive CPU usage under 10.9.1

Hi,
I installed Mavericks on my MacBook soon after it came out and I generally like it. However, it has made my mid-2010 model MacBook quite slow, but, oddly, only in certain situations, for example opening and quiting applications and switching between windows. The Finder has become especially slow. I'm constantly restarting and repairing disk permissions in a vain effort to make my laptop work like it used to, but it still seems almost like the computer is having to use too much virtual memory. However, activity monitor reports low 'memory pressure' (whatever that means) and generally 0 bytes or a low level of swap used. In addition, it seems to be taking longer to start up, especially after it has got past the grey apple screen and loaded up the desktop (I have to wait forever for the dock and desktop icons to appear). It has 8GB RAM and an SSD, so it shouldn't really be slow...
Activity Monitor does report very high levels of CPU utilization (often in excess of 100%). Is it just that the 2.4GHz Core 2 Duo processor is a little weedy for 10.9 or is this irregular behaviour? Any ideas on what i could try to speed this thing up?
Thanks in advance for any help,
LSRW

Hi Dibenkorn,
Thanks for your help. The SMART status is verified and the disk verification finished with a green 'okay' message. I have run etrecheck and the results are below. I will now attempt to reset SMC.

High CPU & Memory issues - Excessive and unnecessary CPU usage in Firefox for Windows (see also questions1003966 & 998289)

I am using the latest version of Firefox, 32.0.1, on an HP Pavilion dv7-4141sa laptop computer, running Windows 8.1 Pro 64-bit. There should be more than enough power here to run a browser without any problem, yet the computer is regularly being overloaded by the browser's resource usage.
I am currently measuring typical average CPU usage of 45% - with the browser minimised. That is to say, Firefox is not doing any browser jobs - it is not drawing on the screen - but it is using the most CPU of any process currently running. Why?
I am an ex-software engineer, and my understanding of current application development technology is limited, but I think I can say with some confidence that many techniques and software architectures exist that enable the suspension of program activity, or at least its reduction to a very low bare minimum, when the program is not actually carrying out its design function, which is in this case to draw pictures of website data on a screen.
There is a very serious problem here, one which means that I cannot run Firefox all the time, but have to kill it when I am not actively browsing, otherwise other applications cannot run to their full capacity. This is a great pity, because I have committed a lot of effort to making Firefox my primary web tool. It manages all my many bookmarks, contains my secure password manager (LastPass), manages my web security (via NoScript, AdBlock, and FlashBlock), just for a start.
Before any well-meaning moderators or other commenters start down the usual trail of "have you done this, tried that, disabled the other", I should point out that I have followed all the advice I can find, with no positive outcome. This computer is running a fresh installation of Windows, and a fresh installation of Firefox. At the moment I am running a new test Firefox profile.
The latest version of Adobe Flash, 14.0.0.179, is installed but disabled. When it is enabled and in use, Firefox's CPU usage seems high over longer periods, but overall there is little difference. It doesn't look as though the problem can be laid at Flash's door. A few other add-ins are installed, mainly those mentioned above, and Firefox is skinned with LavaFox v2-Green, but I have previously started from a clean installation, which has made little difference after an initial period during which things seemed to be better. Turning off or disabling various add-ons has made no discernible difference.
Just now I turned Flash on, and after a long period with Firefox minimised, Resource Monitor reported Firefox at 8% average CPU and FlashPlayerPlugin at 0.32%. While running a small video, RM reports FlashPlayerPlugin at about 45% and Firefox at 8%. After the video, Flash went back down to around 0.4%, and after a bit more browsing Firefox went to around 17% minimised. There seems little rhyme or reason here, except that Flash does not seem to be the culprit, although Firefox does seem to consume less when fewer tabs are actually active, as you might expect. I just refreshed more than a dozen tabs, and now Firefox is at 30%, but still not back up to the higher figures. Weird.
The CPU usage does vary a lot around the average, but 30% is still a lot for a program that shouldn't be doing anything above the minimum status maintenance, and still puts it at the top of my Top Process Monitor list. (Right now it's gone back up to 45%, without my using it in any way).
I have Telemetry turned on, so presumably Mozilla is recording some of the relevant data.
This is a very serious fault, which is more or less reproducible and which a lot of people seem to be experiencing. Probably more people have it than realise, because most users will not know anything other than that their computer slows down for some non-obvious reason; they may just think it's something to do with the computer itself, not knowing how to use the Resource Monitor and interpret the results.
Oddly, the problem does not seem to occur when running Firefox under Linux Mint 17, where the response is snappy and the CPU usage ostensibly low; I am going to look at this in more detail shortly.
I am not posting here for advice, but for information and as a form of bug report which hopefully other users will see. It will hopefully spare them a lot of effort and time in trying a lot of recommended "solutions" which will not work. The problem is inherent in the software, and can be solved only by Mozilla.
I am willing to supply any diagnostic data requested; as I said above, I have also turned on "Telemetry". However, I will not be trying out any more reinstallation/new-profile/add-on disable-enable-delete cycles unless I am asked to for very specific reasons. Please do not suggest courses of action which have already been mentioned elsewhere on this forum. I have tried them all.
The situation is very disappointing, but I have confidence that the Firefox developers will pin down the fault eventually and engineer a satisfactory solution that makes it viable to leave Firefox open all the time. Even with that restriction, it's still far better than the alternatives.

I share jmward's frustration. This is not a bug report so much as a request for a badly needed feature, ie the ability to have Firefox be able to tell us which tabs on which windows are eating time so we can target them. There are some very poorly written web pages out there which just plain loop while making no updates or inconsequential updates on the page.
This is not a OS problem; jmward runs Windows and I run Linux but we have the same issue. It is not a question of Firefox plugins or extensions, or even viruses; I have a new, clean Linux install but have the same problem on both my regular Firefox AND on a FRESH install of the latest Firefox (35.0.1) which has *NO* non-default plugins or extensions.
Here is an example of a web page which will eat 100% of one CPU's time:
http://patch.com/massachusetts/arlington/arlington-woman-allegedly-attacks-neighbor-snow-blower-0
I will attach 3 images to back up my claim. All of the images show my dark blue system monitor (gkrellm) superimposed on the web page. The top graph shows CPU time. I have 4 CPUs in my machine, so 25% means the web page is eating 100% of one CPU equivalent.
The first image shows the load of the offending page with elevated CPU usage along with the download net activity on eth0, but the CPU activity does not stop when the download activity is over.
The second images show the steady state 100% CPU equivalent of this page just sitting there apparently doing nothing. It IS, however, doing at least two different things. I know from my regular Firefox where I have "Remove It Permanently" installed that if I remove the the little weather indicator in the upper right of the offending page that CPU utilization drops to about 40% of one CPU equivalent. If I use RIP to remove everything else right down to a bare screen that 40% utilization stays until I delete the tab.
The third image shows the CPU utilization drop to zero when I delete the tab holding the offending page.
Now I will add a note here: If the offending page is NOT the top tab in a window then it stops eating time. The offender will also stop eating time if I minimize the window. However if I have another window up but leave the offender up on top in its window it continues to eat time even tho I am looking at another window. The offender will continue to eat time even if its window is completely covered by another window, and it will also eat time if I switch to another desktop.
I will often have half a dozen windows open, and there are many pages out there which will suck endless CPU time. Unless I want to open up a new tab on each window before I leave it there is likely to be some tab on top eating time uselessly. Get a couple of those going and Firefox becomes sluggish and can even stop responding for many seconds.
I guess I not only want to have Firefox tell us which tabs are eating time, but I would also like it if Firefox would stop giving CPU time to any tab which is not visible because it is covered by some other window and/or it is on a desktop which is currently not showing. If you can stop a tab's CPU usage by reason of tab-not-showing then you should also be able to stop its CPU usage when the window is covered or on the not-top desktop. Indeed is there any reason to not schedule absolute CPU utilization priority to the visible tab on the window with focus and give time to the other tabs only when the visible tab isn't using time?
My final thought on this is that I have had Firefox SO tied up sometimes that I swear their are web pages which are eating time even tho they are not the top tab. I regret that I do not have an example to show you. But Firefox grinds to a complete halt on a regular basis, and that is not acceptable. I am a programmer with long experience in multi-threaded programs so I *know* there is no reason you cannot do better. If there were another browser around which had the commitment to privacy which Firefox has I would probably switch out of shear annoyance. :-(

10.9.4 excessive CPU usage

And now a strange case...
Installed 10.9.4 but it became unusable because of excessive CPU usage. Reverted back to 10.9.3 but now the problem persists!
Basically, if connect the Ethernet cable the CPU increases and temp raises from 45C to 95C. As soon as I remove the Ethernet cable and stay on WiFi things go back to normal. I already have done the most obvious, i.e. reinstalling the OS from time machine, removing launch daemons and plug-ins, and fixing disk permissions. Check the details below. Any idea? It would be much appreciated. I'm getting nuts with this.

Please read this whole message before doing anything.
This procedure is a test, not a solution. Don’t be disappointed when you find that nothing has changed after you complete it.
Step 1
The purpose of this step is to determine whether the problem is localized to your user account.
Enable guest logins* and log in as Guest. Don't use the Safari-only “Guest User” login created by “Find My Mac.”
While logged in as Guest, you won’t have access to any of your documents or settings. Applications will behave as if you were running them for the first time. Don’t be alarmed by this behavior; it’s normal. If you need any passwords or other personal data in order to complete the test, memorize, print, or write them down before you begin.
Test while logged in as Guest. Same problem?
After testing, log out of the guest account and, in your own account, disable it if you wish. Any files you created in the guest account will be deleted automatically when you log out of it.
*Note: If you’ve activated “Find My Mac” or FileVault, then you can’t enable the Guest account. The “Guest User” login created by “Find My Mac” is not the same. Create a new account in which to test, and delete it, including its home folder, after testing.
Step 2
The purpose of this step is to determine whether the problem is caused by third-party system modifications that load automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Please take this step regardless of the results of Step 1.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of Steps 1 and 2.

Mountain Lion Mail excessive CPU usage

Evers since upgrading to ML 10.8 and 10.8.1, Mail heats the CPU up to 100% after a couple of minutes and remains like this forever. Absolutely reproducible. Mail is unusable for me.
I have some 25.000 Mails in my Inbox. Sampling Mail always reveals the same pattern. Looks like Mail is constantly iterating over my 25.000 emails and tries to layout them. Looks crazy to me.
Here is an excerpt of the sample:

This problem was solved.
After a lot of frustration (restoring Lion backup and performing the update several times), I managed to have a stable installation without the problem of high CPU usage and high temperatures.
It seems that the installation procedure has an issue, when your user directories are located in an external disk. In this particular case, after the installation of the server software, the two links in /Network/Servers directory, pointing to the / directory, do not get created, so you need to do that manually.
That, in itself, was not causing my excessive CPU usage, but it didn't allow my users to log in the server. Thinking that this was the issue described in http://support.apple.com/kb/TS2938, I was running the command described in the previous link to fix the issue. That command (sso_util configure -r REALM_NAME -a diradmin afp) was what was killing my CPU.
All is well, when it ends well, I guess.

How could i get the kernel and user cpu usage for each process

Hi all,
In order to monitor the system CPU usage, I would like write a script to gather the kernel and user CPU usage for each process, like the prstat or top does. As always missing the shortlived kernel usage, prstat or top cann't get the precise CPU usage. I checked with the dtrace syscall, proc and fbt provider, but don't get which one is useful.
Please provide your comments and suggestion.
Thanks in adv

As I've studied the "dtrace" for a while, and seems Sun gives a pretty high score on this new feature.....I do want to know whether there's some probe can work for it, like writing a "dtrace" version prstat.You can write a prstat without dtrace. Because that's just polling at specific intervals and reading some process structures from /proc. You could have dtrace fire a probe every 5 seconds and read the same thing, but it wouldn't really be using any features of dtrace. Trhying to write it "in dtrace" doesn't make much sense.
What you could do that would be harder via other methods is to fire a probe at process exit that displayed the process information including total CPU time. They could print exactly when processes exited. Doing that without dtrace would be very difficult.

High Fan Noise and 100% CPU usage by Dock

My MacBook Pro 3.06 GHz Intel Core 2 Duo running 10.6.8 just started making a constant fan noise. When I checked the Activity Monitor, it shows my Doc CPU usage as 100%, and my Percent User Usage is about 52% System 2.5% and % Idle is 47%. These numbers are when there is nothing running except Activity Monitor. When I log out and log in as another user, the high fan noise stops, and the CPU usage of the Doc is <1%. I have tried restarting my computer, Rebuilt my Permissions, Emptied the Trash, and Reset the SMC (I think I did it correctly for the MBPro, but the Power Light did not change, and nothing seemed to be any different on my computer.) I think I recently did a recent Apple Update, but I don't know how long ago that was. But it was sometime in the past few days. Does anyone have any idea about what could be going on?
Thanks,
Frank

Prstat displays PROCESS/NLWP with /0 , but high USR and SYS cpu usage

I'm running prstat on Sol 10u4 sparc and see from time to time one of more processes with high user and kernel cpu usage, The process name is just displayed as " /0". What is this ?
see sample snapshot below:
PID USERNAME USR SYS TRP TFL DFL LCK SLP LAT VCX ICX SCL SIG PROCESS/NLWP
18738 root 18 42 3.5 0.0 0.0 0.0 36 0.5 123 247 15K 0 sort/1
18728 root 10 30 1.0 0.0 0.0 0.0 0.0 59 0 361 16K 0 /0
18737 root 6.8 15 2.1 0.0 0.0 0.0 75 0.2 82 82 5K 0 awk/1
18731 root 5.2 12 1.3 0.0 0.0 0.0 80 1.5 68 0 5K 0 /0
18730 root 4.8 10 1.1 0.0 0.0 0.0 82 1.4 58 58 4K 0 /0
18736 root 4.4 10 1.1 0.0 0.0 0.0 84 0.1 63 0 4K 0 grep/1
18732 root 3.0 11 2.1 0.0 0.0 0.0 0.0 84 0 45 3K 0 head/1
18735 root 4.3 9.2 1.1 0.0 0.0 0.0 85 0.1 57 57 3K 0 grep/1
18729 root 4.3 8.7 1.2 0.0 0.0 0.0 84 1.3 103 51 3K 0 /0
18734 root 3.7 8.9 1.0 0.0 0.0 0.0 86 0.5 52 52 3K 0 grep/1

The slash number format is used to show the number of threads (light weight processes or LWP in Solaris parlance) in a given process (see the header says "PROCESS/NLWP"). I'd guess this is a race condition where prstat finds a process exists and has consumed some CPU, but when it goes to query the data on the process it's already exited so there's no process name and zero threads associated with it. For this to be true and to see this except more than every once in a blue-moon you'd have to have a system that was having processes forked at an amazing rate.
I'd also say this is a bug, but one that you might have a hard time getting an traction on.

Flash: excessive CPU usage

I'm on Mac OS X 10.5.7 and latest version of flash 10,0,32,18, and I notice that CPU usage is really excessive for pretty much any page that has even a small flash content embedded in Firefox 3.5.1. Just having for example a paused flash video uses 16% CPU constantly, and playing the video spikes the CPU usage from 56 to 76%.
And this is on dual Xeon, 2.8 GHz, 8 core Mac Pro with nVIDIA GeForce 8800 GT 512 MB video card, and 32 GB of RAM. I can only imagine how really frustrated users on notebooks must be.
I think flash is really reaching the tipping point where it is becoming unusable and it is really time to start looking into sane alternatives.

I do agree. Though, to be fair, people use the software that Adobe creates to create their own software that runs in the flash player. The player can be as well written as it is possible to be, and still have this type of problem if independent developers write poor software. This is not in Adobe's control.
My note is that it is a known bug for player 10 to be excessively wasteful on the Mac platform, regardless of how well the program running is programmed. This is a bug that they are currently working on fixing, to all publicly facing knowledge.
The only way to truly get rid of this is to get the developers out there in the world educated in good programming habits. Actionscript 3 has done a lot in terms of pushing the community towards that goal, but bad practices are still extant. People don't remove event listeners when they are finished with them. People don't set variables to null for garbage collection. Both of these are probably the biggest problems, leaving things in memory that you aren't even using anymore. And there is nothing Adobe can do about it except attempt to educate the masses.

USB Devices Not Detected and High CPU Usage

Hello, I'm using arch on a Dell 1720 laptop.
I have some weird issues involving detection of USB devices.
When the laptop is on battery and I plug in a USB mouse the power flickers on and flickers off again; nothing in the logs/dmesg.
If I then connect the AC adapter the reconnect the mouse, the same happens, except the CPU usage hits 87%+ on one core.
Running
sudo rmmod ehci_hcd
solves the problem; the CPU usage drops and the mouse gets detected.
Subsequent attempts to hotplug USB devices does nothing, no high CPU and no Power.
Rebooting the computer is the only way to use USB devices at the moment.
usb-autosuspend is disabled in laptop-mode.
uname -a:
Linux MatSalleh 2.6.39-ck #1 SMP PREEMPT Sun Jun 5 18:30:30 EDT 2011 x86_64 Intel(R) Core(TM)2 Duo CPU T7250 @ 2.00GHz GenuineIntel GNU/Linux
The same happens with the stock kernel too
My kernel line in grub:
kernel /vmlinuz26-ck root=/dev/sda3 elevator=bfq ro resume=/dev/sda2
Any ideas?
Thanks,
Chris.

I highly doubt it's that, it was working fine on ubuntu just days before...
tydell wrote:I had similar problem with USB pendrive, it wasn't detected and it makes high cpu usage. It was problem with ehci_hcd module
This one helps me to solve this problem
My USB devices don't even get detected, so that script won't work.
Last night I hibernated my computer after not using any USB devices, on resume, my CPU usage was 100%, removing the ehci_hcd module fixed it.
Any more ideas?
I'm tempted to build a vanilla kernel...

K8NGM2-FID problems: no usb and high cpu usage - HELP!

hi folks,
i've setup K8NGM2-FID inside an htpc with a clean install of mce 2005 (onboard video). For the past couple of days I've noticed a few things:
1) if the pc goes into standby (S3) and then wakes up, sometimes task manager shows a cpu usage of 50% (on the graph) but looking at the list of tasks (for all users) nothing is runing that high - in fact system idle process shows 98% (while the graph is still showing about 50%) and the system is a bit sluggish; reboot fixes this but it's getting really annoying. I've installed the latest AMD x2 driver. Sometimes it goes to 98-99% after waking up but that's been rare.
2) i've been getting a few BSODs lately, actually all started yesterday - 3 of them in a span of about 2 hours after insalling Nero. I'm going to try to figure out what is causing it that (proabably Nero - I hope since that's easy to undo) but what i've noticed is that when the system reboots after the blue screen, none of the USB devices work (i.e. keyboard, mouse, etc.). windows has to load, then I need to go in the back and unplug/replug the usb devices which then 'wakes' them up; this can get really annoying in a typical cramped home theater setup. software restarts seem to be good - ok hardware restarts are the problem. hooking things up to a usb hub has the same effect - i.e. I need to re-plug the hub to get them to work - it just means less things to plug/unplug.
has anyone else noticed this? help save my sanity - this is driving me crazy. since this is an mce setup, it goes into sleep and wakes up several times a day so the high cpu issue when it comes up really gets in the way of using the pc. btw. during high cpu times, no mce related function (record/watch/the shell itself) is running.
here's my setup:
K8NGM2-FID - boots up with 3 short beeps - I think it's 1 beep pause then 2 beeps
2 gigs kingston 3 CAS (2 x 1 GIG kit) pc3200 - boot screen shows it running at 400mhz in dual channel config
X2 3800+ stock fan/heatsink with silver 5 (runs around 35-38 idle - inside a silverstone 'stereo rack' case)
ms usb keyboard/mouse/mce remote
coolmax 550W power
3 140GB WD drives (ata 133 - not sata)
onboard video - framebuffer set to 128megs
latest (as of 2 days ago) nvidia and msi drivers - msi bios is the stock 3.0 (more on that later)
the bios settings are all default as far as I can tell.
pvr-150 tuner card
promise ata 100 card
nec 3500dvd
all running on mce 2005 with rollup 2 and all the updates windows could find
i haven't updated the bios because i've read about other folks having blue screen problems and the suggestion has been to up the voltage for the ram (I guess the default setup from MSI is lower than it should be) but apparently that option is missing from the 3.1 and later bioses? and reading the text file, it wasn't very apparent what the bios 3.1 was fixing other than a few cosmetic bootup texts. I'm planning to up the voltage later today.
anyhow, any suggestions short of throwing the entire pc out the door are welcomed.
thanks!

ok here's what I've found about the high cpu...
using process explorer, hardware interrups is taking all the cpu. i've tried to disable items one by one but nothing is working so far. what does work is if i choose scan for new hardware, cpu goes down to normal. standby and resume and cpu is up again. do the scan and it goes down again - without changing anything.
i've re-installed the graphic board driver, nvidia 430 drivers, sound driver. not sure what else to do. checked my drives and they are all properly master/slave set.
this is really getting crazy...anyone come across this?
i'm a bit hesitant to go to bios 3.1 since i've seen lots of posts about BSOD and i've just gotten rid of that.
thanks
thanks a bunch!

High number of threads and high CPU usage on a single instance

Without any apparent reason, in some moments of day the website reports an increment of the HTTP Queue Length from an average of 10/20 queued requests to 100/200 and more.
In that period of time the Average Response Time increases but the number of the requests on the website don't. Even increasing the instances it doesn't help to resolve the problem (maybe it just reduced it).
It seems that the problem is not related to the traffic on the site. This issue happens either when the traffic is high or low.
The autoscaling works well, we don't have peak of traffic but always a slow increasing of requests and the CPU is always below the 50% (memory too). The issue is resolved by the swap of the site and sometimes it's resolve by itself after a while.
What I discovered when the issue happens, is that there's an instance (just an instance only), that has an high number of threads and CPU usage on the W3WP.exe process and these values are above the mean than the other instances. Eg, instances are around
50/60 threads and 10/20% of CPU, the instance with the problem has 200 threads and 50/60% of CPU. If I kill the W3WP process on that instance the issue is resolved.
I monitored the HTTP requests, I tried the website extension "Diagnostics as service" but I can't discover anything that can help me to understand the problem. Of course, there are many requests that go in timeout but it is a consequences of a
unresponsive instance.
On the web hosting plan there are only two sites: the production site and its staging which is used for update of the production only and it's always sleeping. Plus, no webjobs are running on this site.
What can I do to gather useful information that can help me to understand the reason of this problem?
Thank you!

"Does the instance with the high counts receive more traffic than the other instances? Is it possible that the load balancer not
working the way it should be?"
How can I get that information? I can't see metrics for a specific instance
"Does it always happen to the first instance?"
I will check it better, but in the order given by the Processes panel it's the second instance which has the issue. The scaling is at 2 instances for the most part of the time (it's the minimum).
Maybe one time it was the 3th instance but I'm not sure, I'll give it more attention.
" How long do these moment last?"
The time can be 10 to 30 minutes, but I fix it as soon as I see the problem. It's not the down-scaling to resolve it because in these situations the CPU as well is high so the scaling holds or increases the number of instances.
"- How often do these moments occurs?"
It occurs quite often, 2/4 times a week.

Newbie having problems with noisy fan and high CPU usage in Activity Monitor

I am new to the world of Apple and have got my hands on a hand-me-down PowerBook G4 version 10.4.11. It works fairly well for everything but the Internet.
One of the first symptoms i noticed was that watching stuff on youtube was slow and jumped a lot. I checked a few things out and looked the CPU usage in activity monitor and this was about 80% to 100% when on youtube or even moving from page to page. I'e tried loads of stuff including repairing disk permissions, emptying caches and relaunching finder when the preferences file is on the desktop (not really sure what that was supposed to do).
The next thing I discovered was that if i disconnected the laptop from the mains and played youtube and some other applications the whole thing would go into sleep mode very quickly. I have got temperature monitor downloaded now although I already know it is getting very hot.
PS when it heats up the fan turns on because I can hear a whirring sound...
Would really appreciate some insight into this as it seems to be a good runner otherwise.
PS2 I have loads of free space left in the disk usage tab in activity monitor.
Big thank you in advance

Welcome to the world of PowerBook!

Virtually no G4s are dealing well with web video anymore. The video technology used by modern developers puts a huge strain on a G4 processor. As this a choice made by coders, there is not much you can do about it. Some people suggest adding RAM but the effect is marginal considering it's the processor that's taxed.
Notebooks get hot. The fans in my 1Ghz 17-inch PowerBook from 2003 kick in between 130 and 140°F. The danger point is not until in the vicinity of 100F so don't sweat it to much. Make sure you do not cover the case bottom by setting the computer on a thick cloth placemat, pillow or other bedding item, or on your lap without a lapboard. The bootom of the case is part of the heat dissipation system and needs air under it to work
A lot of PowerBooks have, by now, lost some or all of their "feet" that gve a little space under the case. Don't bother looking for official replacements--get the silicone door/drawer bumpers from the hardware store that stick on. I found some about 3/16" thick that let more air under my PB thatn the mostly missing originals.
The next thing I discovered was that if i disconnected the laptop from the mains and played youtube and some other applications the whole thing would go into sleep mode very quickly
Your battery is likely dead from old age. Batteries only last about 2-3 years. You are seeing a sign of the battery lacking sufficient remaining capacity to run the computer. Get this utility:

(you'll need the 2.6.6 version for Tiger) and post what is says about "Health" and "Cycles."

Xorg-server 1.9 excessive CPU usage through a 32-bit chroot - bug?

Xorg goes crazy tapping my cpu usage when I compile in a 32-bit chroot. >60 % of the total CPU is going to Xorg rather than to gcc (running Gnome if that matters). The htop screenshot below shows X and gdm using it. I know that if I start gnome from init 3 without gdm the same problem occurs except htop just shows X as the culprit.
X :0
Further, packages fail to build when I run makepkg through X. If I run it when I'm in init 3 without X at all the very same package successfully builds. If I leave myself logged into Gnome and open tty1 and enter the chroot there, it builds.
Any thoughts why? That has to be a bug in Xorg given the conditions I explained above. Does anyone have an idea as to preventing this?
I entered the 32-bit chroot via: linux32 chroot /opt/arch32 /bin/bash
The package I was attempting to build under X is a kernel if that matters; here is the last bit of the log before the error:
