8.1 system process spiking cpu, disk, and network utilization.

Hi all,
After the most recent update to 8.1(I believe it was Mon 5/19/2014,) my laptop has been giving control to another program for about half a second, and then returning it to me. If I am typing, nothing comes up during that
moment, the menu bar changes visually, then it quickly reverts. This is more annoying than malicious. After some digging I found that cpu, disk, and network all spike at the same time, about 5 seconds apart. Here's what I've gathered:
Task Manager: Under the process tab, Windows Problem Reporting,(under background processes), pops in and out when the problem occurs. This is EXTREMELY odd as I've disabled the Windows Error Reporting service. Under the performance tab, The spikes are all
concurrent and similar in appearance, as shown on the graphs.
Services: When I *stop* the Windows Error Reporting service I get: "Windows could not stop the Windows Error Reporting service on local computer. The service did not return an error. This could be an internal
Windows error or an internal service error. If the problem persists, contact your system administrator." So I have *disabled* it.
Resource Monitor: I find multiple instances of WerFault.exe using different pids. They are under network activity and tcp connections, all pointed at 157.56.141.101. A quick look-up revealed that this address is registered to Microsoft.
Wireshark: My machine is initiating a TCP 3-way handshake to the above mentioned IP address, originating from random port 50379 and destined for port 443. Using TLSv1.2, I see a key and cipher change, an encrypted handshake, and then appliction data being
transferred. The conversation ends with a 3-way goodbye, BUT immediately after the fin ack, my machine sends a rst ack and the conversation begins again. Ad nauseam.
Any info or help would be greatly appreciated. I feel like my machine has the literal hiccups. I've run Avast and MalwareBytes to eliminate malicious software. Both came up clean. I have no issues detected
in Action Center. The most recent thing I've done was install HP drivers for my PhotoSmart D110a. I have uninstalled both the drivers and software from HP. To be honest, I am completely over Windows 8. I feel like I've had nothing but problems with it. Way
too much going on with it. I'd rather have few features that work, than a million that are sub par in every sense of the phrase. End rant. If you need any more data or information from my end, please let me know. Will be more than happy to help you help me.
Thanks in advance for your time.
Bryan
p.s. I had to delete the screenshots due to my account not being verified and I can't figure out how to verify being that it doesn't ask for my email. In doing so, the text has been resized. Apologies in full.

I figured it out. I didn't look in event viewer. The issue was Asus Smart Gesture was crashing and restarting and then crashing again. This caused Error reporting to constantly send the issue. I entered the asus folder, ran the uninstall.bat, and re-installed
it. Solved it immediately.

Portege Z930 - "System" process: high CPU usage when on battery

I've got a Portg Z930.
A process called "System" appears on the task manager when I unplug the PC from the AC.
I'd like to know why is it using high CPU (from 9% to 18%) and keeping my temps above 70C.
It's very annoying, not only because of the temperature that hits the PC itself, but also because of the battery life, that can't go above 1 hour and 30 min because of this process.
It's not a virus, already CHECKED, don't ask.
Also, I don't know when it started or why, so please don't ask.
Thanks in advance,
Nicols.

> I'd like to know why is it using high CPU (from 9% to 18%) and keeping my temps above 70C.
I dont know exactly what this system process does but usually the Windows system uses different power plans / modes while the notebook is connected to AC adaptor and while running on battery power.
So possibly the power plant for battery mode is configured differently.
I would recommend checking the power plant which is used while the AC adaptor is connected and compare the settings with the power plant used in battery mode.

System Processes Hitting speed bumps and Stopping

Within the last few weeks, my MacBook Pro 15 or its system software (Mac OSX 10.8.2) or something else (a background app?, a clocked process?, ???) will suddenly interrupt everything, if only momentarily: all processes stop, songs stop playing, typing halts, mousing disables, and the color wheel starts spinning. It seems to come out of the blue with no rhyme or reason to it.
I have been unable to track down the cause of this frustrating stoppage of literally everything for several seconds before it starts up again.
Along with this is a major slowing down of all processes. I give out a command, or click on a link, and there's a significant delay in responding.
This seems to occur about every 30 minutes, but I'm trying to detect a real pattern.
I will type several words and find no letters appear for a few seconds, then, without warning, the entire line typed appears.
This slowdown and process interruption cannot be tolerated. Help, please

Then uninstall ClamXAV. There is something wrong with that software. If you don't have the uninstaller, then see:
Uninstalling Software: The Basics
Most OS X applications are completely self-contained "packages" that can be uninstalled by simply dragging the application to the Trash. Applications may create preference files that are stored in the /Home/Library/Preferences/ folder. Although they do nothing once you delete the associated application, they do take up some disk space. If you want you can look for them in the above location and delete them, too.
Some applications may install an uninstaller program that can be used to remove the application. In some cases the uninstaller may be part of the application's installer, and is invoked by clicking on a Customize button that will appear during the install process.
Some applications may install components in the /Home/Library/Applications Support/ folder. You can also check there to see if the application has created a folder. You can also delete the folder that's in the Applications Support folder. Again, they don't do anything but take up disk space once the application is trashed.
Some applications may install a startupitem or a Log In item. Startupitems are usually installed in the /Library/StartupItems/ folder and less often in the /Home/Library/StartupItems/ folder. Log In Items are set in the Accounts preferences. Open System Preferences, click on the Accounts icon, then click on the LogIn Items tab. Locate the item in the list for the application you want to remove and click on the "-" button to delete it from the list.
Some software use startup daemons or agents that are a new feature of the OS. Look for them in /Library/LaunchAgents/ and /Library/LaunchDaemons/ or in /Home/Library/LaunchAgents/.
If an application installs any other files the best way to track them down is to do a Finder search using the application name or the developer name as the search term. Unfortunately Spotlight will not look in certain folders by default. You can modify Spotlight's behavior or use a third-party search utility, EasyFind, instead.
Some applications install a receipt in the /Library/Receipts/ folder. Usually with the same name as the program or the developer. The item generally has a ".pkg" extension. Be sure you also delete this item as some programs use it to determine if it's already installed.
There are many utilities that can uninstall applications. Here is a selection:
    1. AppZapper 2.0.1
    2. AppDelete 3.2.6
    3. Automaton 1.50
    4. Hazel
    5. AppCleaner 2.1.0
    6. CleanApp
    7. iTrash 1.8.2
    8. Amnesia
    9. Uninstaller 1.15.1
10. Spring Cleaning 11.0.1

Unrelenting coreservicesd process occupied CPU@92% and temp at 96ºC

I started up my mbp, logged in and loaded mail, safari and what not as usual. Having just been turned on, I thought it a bit odd that it as cooking up to 92ºC within minutes. Then I noticed via my iStat menu running on the top bar that CPU usage was committing 92% usage to coreservicesd (Core Services Daemon). I kicked on the fans, propped it to vent the underside and tried to figure out what coreservicesd was. 15 minutes later, 92% of the CPU was still taxed by coreservicesd. I couldn't find anything in the session log. Did a restart and everything works as normal.
So, any insight as to what coreservicesd was doing and why it got seemingly stuck?
Rgds,

What version of iStat menu are you using now? You can always stop a process by opening /Applications/Utilities/Activity Monitor and using that to kill the process.

Hi,
The Azure Diagnostics capability supports the configuration of diagnostics information than can be captured locally on a role instance and then persisted to Azure Storage on some timescale, this only support Azure Cloud service, I think it is useful for
us to analyze the performance, if you don't want to use it, please try to use
Azure Monitoring Service API, for more information, refer the below articles.

Randomly asks to choose disk and network at startup

Just like the subject says. It happens about one startup/reboot in ten; the gray screen, before getting to the Apple logo, asks me to pick a disk (only choice: my Macintosh HD) and a network (only choice: none, I have a wired network, and the Mini's Airport is off). My mouse (plain 3-button + scroll, no driver) is 99% non-responsive during this time. Once I make these "choices" (via keyboard), everything starts up and runs as it should.
I'm posting this in this forum because this is my fourth Mac, and I never had this problem with any of the others. And this Mac has been fine, other than an incurable Energy Saver issue (see that post to see everything else I've done to this point).
It's my mid-2010 Mac Mini (post-refresh). I was using it as my HTPC, and it worked flawlessly. I repurposed it as my own personal Mac. I erased the HD and reinstalled everything from scratch; performed all of the updates (OS X and everything else); and imported my user account from another Mac (running the same OS, 10.6.7).
What's causing this glitch? What else can I do to eliminate it, or at least troubleshoot it better?

I discovered that the above behavior is identical to the OS X Startup Manager being invoked at startup, i.e. holding down the Option key during startup. Except, I'm not touching the keyboard when it happens. Either my keyboard throwing random Option-key inputs, or something else is going on.

'ubd' process huge cpu load

Since updating to 7.2 I have a weird issue with a process called ubd. It has a huge and constant cpu load of between 50-99%. This generates a lot of extra heat and fan noise to accompany that. Quitting the process or rebooting doesn't help.
I read somewhere that the process is iCloud related, but I tried disabling some iCloud services but that didn't seem to help either.
The console displays these lines all the time:
16/10/2011 12:14:35.122 ubd: createSelfSignedCertificate - _createCert returned -25295
and after about 6 tries it exits with code: 254 and starts again.
I guess this isn't really normal, does anone know what might be up or how to fix this?

Good eye. I noticed the extra keychain entries but didn't think to 'trust' the certficiate. Though this has not resolved the issue of ubd spiking CPU usage and more certificates/keys being created (no matter how many I "trust").
FWIW: you can tail your ~/Library/Logs/Ubiquity/{username}/ubiquity.log and see the certficiate errors every few seconds.

Cannot communicate with system processes error

Hello,
It seems after S159 our IDS's started refusing any config updates/remote logins and returning "cannot communicate with system processes" shortly after login and then disconnecting the session. I see there are some patches available on TAC.
I can't tell if the IDS has any of these patches or not. It reports 4.1-4 Should the IDS report a version with a letter of the patch if it has any installed. Also, does this problem sound like the out of memory bug I have seen mentioned before? The memory usage on the sensors reports 98%
Any help is appreciated!

The only indication of a patched sensor is the status list of components, like Analysis Engine. Instead of "(Release)" it will have the patch version.
Yes, this could be the out of memory issue that can occur during a sigupdate.
NOTE: the memory usage portion of show version in 4.x is incorrect because it does not take into account the OS cached memory that is available for use. It may show that most of the memory is used when actually there is plenty available.

BRtools Two-Phase-Backup to remote disk and remote tape drive

Hello,
i want to two-phase-backup a SAP-System to a remote disk and from there to a tape drive.
Backup to remote disk works fine, but can i use brtools to write the backup-files from the remote machine to a tape drive that is connected to the remote machine?
I'm using SLES 10 on both machines.
I can't find anything on the SAP Documentation to this. It ist possible to backup to remote disk and to remote tape, but it is not clear that it works when in Phase 1 of the backup the files are written to a remote disk. It seems like i can only tell brtools to backup the files from a local disc to a remote tape-drive, is this right?
Thanks in advance for your help.
Regards
Phil

Hi Nirmal,
thanks for your answer.
But i can do disk to tape Backups, when i choose "Backup of Disk Backup" from BRtools, i see a list of all Backups i wrote to the local disk and can write them to remote tape by using pipe as backup device.
The only thing is, my Backups are stored on a remote disk, and from there it seems i have to write them to tape with cronjobs using a shell script. That's not my favourite solution, but it's ok.
Regards
Phil

System process constantly writing to disk

While dealing with another hard drive Problem, ive noticed in Ressource Monitor, that the process 'System' is constantly writing to my main drive.
Sometimes its about 100-200 KiB/sec, today ive watched it for a while, and its writing action was 1.5 MiB/sec for quite a while! Later on it was about 300-400 KiB/sec.
Why does this process write so much data to my disk? Considering Windows running times, this adds up to multiple times the size of my hard drive.
Anyone knows whats going on here?

I have a similar, though less severe issue that hopefully someone can help me with. The System process (pid 4) on my dual core Vaio laptop is writing to disk appx. once every 500ms. This is not performance impacting and I considered it just a
minor annoyance until I recently installed a SSD. Since SSD lifetimes are limited by write/erase cycles, I'm concerned these writes are deteriorating my SSD; not good since they're expensive and I LOVE the performance; boots in appx. 15s, instant IE,
etc.
As with the original poster here, the same activity persists in safe mode. Per SSD optimization guidelines I've read elsewhere, I've disabled all fetching (super, pre, etc.), indexing and all logging except Application, Security & System but the
writes persist.
Im using the latest (very recent) driver from Intel (Intel 5 Series 4 Port SATA AHCI Controller 10.8.0.1003 10/17/2011). I've tried other drivers and while the write pattern seems to change (drive activity light no longer blinks), Resource Monitor
shows they're still there. They also cause an additional issue of consuming CPU (?) which doesn't occur with the "recommended" driver I just mentioned.
Anyone know what these writes may be and if/how I can/should stop them? Thanks.
(BTW, love the caffiene->code quote :-)

Windows 8.1 unresponsive with system process at 25% CPU

I have a Toshiba L50-A with an Intel i5-4200U CPU running Windows 8.1 with all current updates installed. At random times (varying from 1 to 15 days but averaging once every 3 days) the "System" process begins using approximately 25% of my
CPU with the usage spread across the 4 logical processors. Using Sysinternals Process Explorer I can see that the thread using the CPU is "ntoskrnl.exe!ExfAcquirePushLockExclusive+0xb54". Once this starts running, tasks (like Process
Explorer) continue to run but I cannot initiate any new task (like Xperf) and can sometimes shut down tasks until the system finally locks up completely. I can find no way to interrupt this condition and have to hard power down the system. I
have investigated all the drivers associated with my peripherals and believe they are up to date. I have also run a severe CPU and Memory test tool for 24 hours and found no issues. I cannot identify anything which changed in my system which
triggered this but when it first manifested it sometimes went 10 or 15 days between occurrences so it could have been a fix or driver but I cannot identify that connection. Can anyone give me an idea of how to investigate this further or what steps I
can take to provide more pertinent data?
Thanks,
Keith

Hi Ckeithh,
Did this issue occur recently ,Have you installed any software recently?
To analyze this issue ,I recommend you to work with the Windows Performance Toolkit. It is included in the Windows Acccessment and Deployment Kit.
Here is a link for downloading the tool
WPT: WPR/Xperf: Capture high cpu, disk i/o, file, registry, networking, Private bytes, Virtual bytes, Paged Pool/Nonpaged pool and/or application slowness

I recommend you to try this tool to capture the process ,if you have troubles in analyzing this . Please upload the files you captured to the Onedrive and paste the link here.If this tool can`t be performed, please post back.
Meanwhile, I recommend to get into safe mode to work with the predefined drivers and services to have a analysis.

Kill a root system process and have it stay dead until next reboot

The process in question is UPDATE
it does its thing at exactly 30-second intervals
according to this
http://www.westwind.com/reference/OS-X/background-processes.html
it's "responsible for keeping disks synchronized with the file system cache, to keep data loss to a minimum in case of a crash."
I don't care if my disc cache is in sync while I'm playing an ACTION GAME, but it's really annoying when my character dies because the screen stops updating for 0.5 seconds while UPDATE does it's thing. Gaming is pretty much useless with this process running.
Is there anybody out there who can help me to either:
1. kill the Update process and have it stay dead till the next reboot, or
2. tell the Update process to do it's thing at longer intervals instead of 30 seconds (like maybe 30 HOURS)
Thanks for any assistance!

You can find out what defaults it is running with using "ps ax | grep update" (if it is called "update" as it is in Tiger). I very much doubt that configuring it in single-user mode would have any lasting effect - my guess is that you would have to configure the startup file which controls it. If you do this, though, the change will hold whether you are gaming or not - and even if you don't care about the integrity of your disk then, you may at other times.
Note that "data loss" here may not just mean your personal data - it might include the integrity of the file system as a whole. That is, you might end up with an unbootable system. I don't know this, but it may not just be a question of losing changes to user documents, say. The manpage for Tiger doesn't mention data loss but only the integrity of the volumes.
Also, killing it may not work. If it is considered an essential process, the chances are that the system will restart the process if it dies or is killed - certainly that's true of some other processes in Mac OS X.
If instead you gave your game higher priority, when you quit the game, things will go back to normal. I definitely think it would be worth trying that route first. Should you decide to try killing update or reconfiguring the way the system starts up, make sure that you backup everything first. A good way is to clone your system to an external drive and then boot from that clone and ensure everything works as you expect.

Repartition disk and reimport the whole system

Hi everyone,
I have a working Arch Install and I love it. The only problem is that I need to repartition my HDD. The partition scheme is just slightly different. One partition that is now logical will be primary and most partitions (except one) will be slightly larger but that's it.
Meanwhile I need to reinstall Windows (I have a dual boot), then "copy/paste" my whole Arch system back and reinstall GRUB. For now I can think of a few problems.
1) If I reinstall GRUB from a live CD (would it work with Arch's install CD ?), will pacman still handle updates for it ?
2a) A friend advised me to use rsync to copy ALL of my system to an external HDD (I have JFS and ext2/3 partitions) and then use rsync again to recover my system (I was thinking of using a JFS external hard drive). Is it a good idea ? Will this keep all the needed metadata (privileges and such) ? Will it preserve symlinks ? hardlinks ?
2b) Is rsyncing really better than just copy-pasting all files ?
3) I guess I'll have to change my /etc/fstab once I have repartitioned, are there any other files to edit when I have my new partition scheme ?
4) How can I check that nothing has been broken/corrupted in the process ?
Are there "better"/alternative ways to do what I want (Repartition disk, reinstall Windows and get back my whole Arch system) ? What other problems could I encounter ?
Thank you in advance for your answers and sorry for my English (it is not my first language).

yms wrote:1) If I reinstall GRUB from a live CD (would it work with Arch's install CD ?), will pacman still handle updates for it ?
Should be fine. Grub doesn't change that often, and I don't think I've ever needed to re-do grub-install because of an update.

Yes, yes, and yes. However, so will cp -a. If you're just using an external drive attached to your local system to do this, cp -a should be fine.

If you're copying to a separate machine over a network, I prefer rsync. It's easier than net-mounting the target drive and then copying to it, and network filesystems have a way of sometimes mangling ownership & permissions, depending what your setup is. This doesn't apply in your case though.
One caution about just copy&pasting your filesystem (not sure if this still applies with current udev, actually) -- you can't boot with a totally empty /dev. Copying all of the device entries from a booted, mounted /dev/ into your backup and then copying them back works fine, but it's probably better to do this:
mount -o bind / /mnt/temp-root
cp -a /mnt/temp-root/dev /your-backup-root/dev
umount /mnt/temp-root
That'll give you the device entries that are actually in your root filesystem's /dev, before /dev gets mounted on top of it.

crypttab, if you have any encrypted partitions. /etc/suspend.conf if you're using userspace suspend (it'll need to know the new swap partition to resume from after s2disk). mdadm.conf if you have software RAID and are using that. Likewise for stuff in /etc/lvm (possibly).
yms wrote:4) How can I check that nothing has been broken/corrupted in the process ?
On your current system:
find / -type f -print0 | xargs -0 md5sum >> /big-file-checksum-list
When you've got everything copied back:
find / -type f -print0 | xargs -0 md5sum >> /big-file-checksum-list2
Then sort those two files and compare them.

Some things I ran into while installing Windows 7:
- Win7 has a separate 100MB boot partition. As far as I know, it's not easy to pick an existing partition and tell it, "this is your boot partition." I just let the installer create it for me.
- Win7 does not obey some partition table conventions -- I can't edit my partition table with cfdisk because Windows 7 apparently got some disk geometry slightly wrong (You know that 8mb of free space that XP & NT used to leave at the end of disks? I don't think they've fixed that yet). fdisk, parted, and sfdisk are all OK though.
Edit: one of the Win7 problems turned out to be something else; removed it.

When doing catalog backup get message " your system is low on disk space, and elements organizer can

When doing catalog backup get message " your system is low on disk space, and elements organizer cannot perform the operation. If create a catalog with 20 pictures backup works OK. backing up to a 1TB external drive. Have 16705 pictures in catalog. Total disk space for pictures is 192 MB. Why am I getting message?

Do you really mean MB (megabytes) or GB (gigabytes) ?
Even if its GB, the free space may be enough, depending on your files size, especially with videos or raw files.
When you start the backup process, it first shows you the total size of the catalog.

8.1 system process spiking cpu, disk, and network utilization.
