Swiping causes spikes in CPU utilization.

Using app to monitor CPU on iPhone 5 and iPad mini. Swiping causes spikes in CPU utilization from 5% to 65% for every swipe. Heavy swiping causes processor to run near 100%. Seems abnormal.
Reduce Motion turned on.
IOS 7.1
Anything to make this not run so high? Battery drain seems much faster with just general usage.

Hey Apple. This is likely a major issue with battery drain. Constant CPU spikes will cause the CPU to heat which increases battery drain. Swiping should not peg the CPU. I suspect it has to do with how The screen is rendered to the user.somebody needs to look into this from Apple. This is been an issue for at least the last few iOS versions.

CSA causes cpu utilization spike in enforcement mode?

I am experiencing a problem where two servers (specifically a file a server and a Citrix server) are experiencing spikes in CPU utilization (maxing out at 100% util) whenever we take them out of "Test" mode.
These systems are running CSA v4.5-1 build 616 agents. In order to stop the CPU issue, we had to stop the agent (which dropped the processor util immediately), put the system back into a "Test" state, restart the agent, and poll the server.
Now that the server is back in a Test state, the CPU problem doesnt exist.
Any thoughts or suggestions would be greatly appreciated.

CSA is trying to do a lot of work but it isn't logging anywhere because it's set not to.
1. Create a new group called "Windows test".
2. Clone the policies in the group and add them to the new group.
3. Change all the rules in those cloned policies to log.
4. Put the group in test mode.
5. Put a problem server in the group and see what events are generated.
You should see what's causing the problem without killing the server in the process.
Then you'll be able to either except the process or disable the rule causing it (if that's safe).
You also didn't mention what process is spiking the CPU.

Xsun (high CPU utilization) on Solaris 10 Sparc

hi
i have sun blade 1500 and am running solaris 10 on it. the machine is a 2 CPU (750Mhz) 4GB Sparc with the lastest cluster patch.
The Xsun process is alway at 50% util and the windowmaker (wmaker) is at 27%.
The Xsun is alway using all available CPU and the machine is really slow.. any help on what patch will fix the Xsun process ? any operation on the machine increases the Xsun's CPU util.
thx
Sriram

Hi sridhar,
can i know which platform you are using....
if it is solaris,
can you paste the details of the prstat -L -p wlpid 1 1 ---> which gives the light wieght pid threads
and also (pstact wlspid) for lwpid to process id mapping
or you can follow these steps for finding which thread is causing the hight cpu utilization
1.find the highest usage lwpid in prstat output
2.find the lwpid in pstack output and get the matching thread number
3.convert the thread number to hexadecimal
4.find the hexadecimal thread number in the server thread dump (nid= xxx)
5.determine what thread was doing to cause the high cpu usage
you can find similar way if it is linux..
ps u -Lp wlspid and thread dump
Thank you,
Bob

SDK-based Management Pack causes 100% CPU utilization for HealtService.exe

We developed an MP that uses SDK to create SCOM objects and insert a large number of performance counters ~ 2000 every 5 minute interval.
On SCOM side the MP has about 2000 instances of UnitMonitor (only ~20 per class but there are lots of actual objects). In these monitors we use
DataSource based on Microsoft.SystemCenter.TargetEntitySdkPerformanceDataProvider. All worked fine for a year but lately added a bunch of new objects/counters and CPU utilization for the MonitoringHost.exe started to spike
to 100% a few seconds after the Performance Counters were posted via SDK. The spike lasts for up to 3 minutes. No DB or Network spikes observed. We suspect SCOM does not deal efficiently with SDK Performance data - as if a separate SdkPerformanceDataProvider
is started for every UnitMonitor when the counters are posted rather than having cooked-down - one per Target instance.
Can anyone shed some light on this? I suspect only the Microsoft engineers would know.
Our environment is like this:
SCOM 2012 R2 UR4
Windows Server 2012 8 Core, 16 GB Ram
Thanks,
Dave

Hi Dave,
is there a way that you can reduce the number of performance insertions? Regardless of even fixing the performance issue, the impact from a database standpoint may be something to consider in the long term. My point is that fixing one issue, will take us
to the next one, etc etc.
I would reduce the number of insertions, only to the either insertion of the "most critical" or "top #". Also, aren't those counters already captured out of the box?

Multiple Adobe Readers causing High CPU utilization

Recently I've had a couple of instances where my system performance degraded significantly. I checked Task Manager and discovered two Adobe processes accounted for + 80% CPU utilization. Adobe Reader was not showing as an open application. I had closed the application earlier. I rebooted and things went back to normal. The processes were no longer active.
Note: Recently I had a problem with Nitro Pro hijacking my ability to open PDFs. It even removed Adobe Reader from my list of options for opening a PDF.
Has anyone had similar issues? Cause? Fix?

Hi keeperdan ,
Thank You for posting on the forums. Which version of Adobe Reader are you working with? My suggestion would be to use the latest Adobe Reader 11. Also, if you are already using Reader 11 kindly update it to 11.0.06.
Kindly reply if this does not resolve the issue.
Thanks,

BTServer causing high CPU utilization

Just got a new MacBook Pro with OS X Lion and updated to 10.7.1. I've seen the BTServer process cause high CPU utilization twice now. One morning I also noticed that the fan was running loudly while the lid was closed and the computer was locked up; I had to force power it off. Anyone seeing similar issues? Doing a search for BTServer on Google or even here in the Apple Support Communities does not bring up anything related to Lion at all, only iPhone-related articles.

yup, i had this problem too. i have a new 2.2ghz macbook pro and while at a coffee shop, i noticed my battery draining very quickly, and a look at activity monitor showed that BTServer was running away with high-cpu utilization. i killed off the process and didn't notice any loss of functionality.
not sure what it was supposed to do with so much freaking cpu cycles!!!
is this for bluetooth? i dont even have bluetooth on. im not happy about this having to be something i'd need to keep a eye on when i'm trying to maximize my battery life.

Get-MailboxExportRequest script causes high cpu utilization

Our Exchange configuration is as follows:
Exchange 2013 Ent on single server with 4 dbs
DB1 - 191 users
DB2 - 19 users
DB3 - 72 users
DB4 - 7 users
When I run a script that exports all of the users from each db to a pst file the CPU utilization peaks as expected, however DB1 never completes. Is there a way to throttle the performance somewhat or limit the number of users the script processes at
a time? Here is my script:
#Establish variables
$mailserver = "Exchange"
$path = "\\FileServer"
$userlist = Get-Mailbox -database DB1
$ReportShare = "\\FileServer\pst$\reports"
$file = "\\FileServer\pst$\reports\*.txt"
$SMTP = "smtp.domain.com"
#delete files from previous nights export
if (Test-Path $file)
Remove-Item $file
#Clear previously completed & failed tasks
Get-MailboxExportRequest | where {$_.status -eq "Completed"} | Remove-MailboxExportRequest -confirm:$false
Get-MailboxExportRequest | where {$_.status -eq "Failed"} | Remove-MailboxExportRequest -confirm:$false
#Perform Mailbox Export
foreach ($user in $userlist)
$useralias = $user.alias
New-MailboxExportRequest -Mailbox $useralias -filepath $path\pst$\$useralias.pst
#Create a loop which checks if the task has completed or not
$exstat = Get-MailboxExportRequest | Get-MailboxExportRequestStatistics | where {$_.status -eq 'inprogress'}
do {start-sleep -seconds 5; $exstat = Get-MailboxExportRequest | Get-MailboxExportRequestStatistics | where {$_.status -eq 'inprogress'}}
until ($exstat.percentcomplete -eq '100')
#Create a pause for the exports to finish before writing logfile output
start-sleep -seconds 7200
#Write output to a log file
if ($ReportShare)
Write-Output "Writing reports to $($ReportShare)"
$Completed = Get-MailboxExportRequest -BatchName $BatchName | Where {$_.Status -eq "Completed"} | Get-MailboxExportRequestStatistics | Format-List
if ($Completed)
$Completed | Out-File -FilePath "$($ReportShare)\$($BatchName)_Completed.txt"
$Incomplete = Get-MailboxExportRequest -BatchName $BatchName | Where {$_.Status -ne "Completed"} | Get-MailboxExportRequestStatistics | Format-List
if ($Incomplete)
$Incomplete | Out-File -FilePath "$($ReportShare)\$($BatchName)_Incomplete_Report.txt"
#Send a mail notification the task has completed
Get-ChildItem $ReportShare | where {-NOT $_.PSIsContainer} | foreach {$_.fullname} | Send-MailMessage -to "[email protected]" -from "[email protected]" -Subject "PST EXPORT REPORT DB1" -Body "Export of DB1 complete."
-SmtpServer $SMTP -BodyAsHtml

I have to ask why you have a nightly job that exports each mailbox to PST? It's unusual.
Anyway, you could split your script as follows:
Get-Mailbox -Database DB1 | ? {$_.samaccountname -like "[a-m]*"}
Get-Mailbox -Database DB1 | ? {$_.samaccountname -like "[n-z]*"}

Airport Process utilizing high CPU utilization

I currently have a 13 inch MacBook Pro i7 (2012 version). Recently I upgraded to Mavericks. After using the computer for a day after the upgrade, I began to notice it becoming very hot and the fans running very high. Looking at the running processes i noticed that a process called "airport" was running and utilizing high CPU times causing the heating up and fans running. Once I stopped this process, the laptop went back to operating at normal levels.
Unfortunately this issue began to come back several times....the "airport" process starting at any time and utilizing high CPU utilization....again only by killing this process fixed this issue.
After seeing this behavior over several days, I decised to wipe the drive and install a clean copy of Mavericks in the computer. Thought here was that possibly something did not carry over correctly from the upgrade from Mountain Lion to Mavericks. Unfortunely this did not correct the issue with the "airport" process as it still is continiung to launch at any time and spike the processor until I manually kill the process.
I do not recall this issue occuring while running Mountain Lion so it seems to be specific to Mavericks at this point.
I was hoping to hear if any other have experienced this type of issues while running Mavericks.

You should be able to find the information you are looking for from the default Total CPU Utilization Percentage monitor. This monitor has a built in diagnostic task that will kick off when an alert is triggered to list the top cpu consuming processes.
To find which processes were causing CPU to spike, simply review the State Change Events history in health explorer for the machine that was affected, for the Total CPU Utilization Percentage monitor. I have modified my second screen shot
to remove machine names, but you should get the idea. If a cpu monitor went from green to red, it will run the diagnostic task and list the process information and cpu usage at the time of the alert under state change events.

Can we control user request w.r.t Memory and CPU utilization in Oracle 10g

Dear All,
We are having Production with Oracle 10.2.0.4 (5 Node RAC, 32Gb RAM each) running on RHEL5.2 with 12000 Users. We have some schema say FIN, HRMS, SALES, REPORT and many dedicated users for those schemas. We need to control the user request against these schema with respect to Memory (or CPU utilization)
Suppose users using FIN schema can use Maximum 40 % of Total Memory, HRMS schema can use Max 20%, SALES can use Max 20% and REPORT can use Max 20%.
Is it possible to create any Service in Server side to handle this type of scenareo or any existing service which can be customised to fullfil this?
Please suggest me.......
Thanks,
Tusar

JDBC 'applications' quite often don't use persistent connections, and often do not exit gracefully by calling 'exit' or 'disconnect'.
This means the session will continue to exist.
It also means, if you don't establish any form of connection pooling and/or dead connection detection, you can throw whatever amount of memory in the server, and you will continue to report
'Now problems is coming'. Apart from crippled English, the general lesson any DBA should know is how these 'applications' operate, and, contrary to some, you can never ever fight problems caused by applications,
by throwing memory and cpu at the problem.
When I read your text, I also assume the application is not using PrepareStatement calls and not using bindvariables, this is why your 'application' is burning the CPU.
Find those 'application developers', sue them, or better still : Beat them with a whip, and have them fix their 'crapplication'.

Increased CPU utilization on Sup1A after upgrade

Hello,
I recently upgraded a 6009 with Supervisor 1A from CatOS 7.6(5) to 8.4(4). Baseline total CPU utilization before the upgrade was about 12%, post upgrade it sits at about 30%.
We have several similar switches throughout our network that we intend to upgrade as well, so are treating this one box as a testbed. We will soon deploy IP telephones to every desk in our network, and want to determine if this higher baseline utilization will be problematic for us.
Considering voice, should we be concerned about this? Will any changes due to voice deployment such as many trunks, QoS, etc. cause a significant jump in CPU that might put our baseline even higher?
Will the higher baseline CPU utilization affect switch performance? I know most forwarding functions do not depend upon the CPU, and are switched via ASIC.
thanks for the help,
Brad

The IDLE_Tasks process on which you are seeing a slightly higher CPU is actually an enhancement that collects information more effectively on crashinfo files (files generated when there is a crash on the box). This enhancement went into 8.3(x) and 8.4(x)
In the past "IDLE_tasks" processing was not counted and therefore belong to the "kernel and IDLE" process (which as you can see in the show proc cpu) accounts the amount of cpu not being used.
If you are upgrading other 6500's with Sup1a's make sure they all have 128MB DRAM just like this one has.

Performance degrading CPU utilization 100%

Hello,
RHEL 4
Oracle 10.2.0.4
Attached to a DAS (partition is 91% full) RAID 5
Over the past few weeks my production database performance has majorly degraded. I have not made any application, OS, or database changes (I was on vacation!). I have started troubleshooting, but need some more tips as to what else I can check.
My users run a query against the database, and for a table with only 40,000 rows, it will take about 2 minutes before the results return. For a table with 12 million records, it takes about 10 minutes or more for the query to complete. If I run a script that counts/displays a total record count for each table in the database as well as a total count of all records in the database (~15,000,000 records total), the script either takes about 45 minutes to complete or sometimes it just never completes. The Linux partition on my DAS is currently 91% full. I do not have Flashback or auditing enabled.
These are some things I tried/observed:
I shut down all applications/servers/connections to the database and then restarted the database. After starting the database, I monitored the DAS interface, and the CPU utilization spiked to 100% and never goes down, even with no users/application trying to connect to the database. The alert.log file contains these errors:
ORA-00603: ORACLE server session terminated by fatal error
ORA-00600: internal error code arguments: [ttcdrv-recursivecall]
ORA-03135: connection lost contact
ORA-06512: at "CTXSYS.SYNCRN", line 1
The database still starts, but the performance is bad. From the error above and after checking performance in EM, I see there are a lot of sync index jobs running by each of the schemas and the db sequential file read is high. There is a job to resync the indexes every 5 minutes. I am going to try disabling these jobs tihs afternoon to see what happens with the CPU utilization. If it helps, I will try adjusting the job from running every 5 minutes to something like every 30 minutes. Is there a way to defrag the CONTEXT indexes? REBUILD?
I'm not sure if I am running down the right path or not. Does anyone have any other suggestions as to what I can check? My SGA_TARGET is currently set to 880M and the SGA_MAX_SIZE is 2032M. Would it also help for me to increase the SGA_TARGET to the SGA_MAX_SIZE; thus increasing the amount of space allocated to the buffer cache? I have ASMM enabled and currently this is what is allocated:
Shared Pool = 18.2%
Buffer Cache = 61.8%
Large Pool = 16.4%
Java Pool = 1.8%
Other = 1.8%
I also ran ADDM and these were the results of my Performance Analysis:
34.7% The throughput of the I/O subsystem was significantly lower than expected (when I clicked on this it said to either implement ASM or stripe using SAME methodology...we are already using RAID5)
31% SQL statements consuming significant database time were found (I cannot make application code changes, and my database consists entirely of INSERT statements...there are never any deletes or updates. I see that the updates that are being made were by the index resyncing job to the various DR$ tables)
18% Individual database segments responsible for significant user I/O wait were found
15.9% Individual SQL statements responsible for significant user I/O wait were found
8.4% PL/SQL execution consumed significant database time
I also recently ran a SHRINK on all possible tablespace as recommended in EM, but that did not seem to help either.
Please let me know if I can provide any other pertinent information to solve the poor I/O problem. I am leaning toward thinking it has to do with the index sync job stepping on itself...the job cannot complete in 5 minutes before it tries to kick off again...but I could be completely wrong! What else can I check to figure out why I have 100% CPU utilization, with no users/applications connected? Thank you!
Mimi
Edited by: Mimi Miami on Jul 25, 2009 10:22 AM

Tables/Indexes last analyzed today.
I figured out that it was the Oracle Text indexes synching to frequently that was causing the problem. I disabled all the jobs that kicked off those indexes and my CPU utilization dropped to almost 0%. I will work on tuning the interval/re-enabling the indexes for my dynamic datasources.
Thank you for everyone's suggestions!

Total cpu utilization percentage diagnostic removed from Windows 2008 MP?

SCOM 2012 SP1 environment running the Windows Server 2008 Operating System Management Pack, version 6.0.7026.0
http://www.microsoft.com/en-us/download/details.aspx?id=9296
We had a server that had high CPU utilization. We were able to figure out what process was causing the high CPU using some remote commands, but I am used to seeing this in the health explorer state change events view.
I looked into health explorer but there is no data.
http://i.imgur.com/eArmCM2.jpg
I then notice that in this MP, there are 2 CPU monitors
http://i.imgur.com/I9eBN4G.jpg
The first monitor shown is disabled by default, but it is this monitor that contains the diagnostic to list the top CPU consuming processes
http://i.imgur.com/tLgq9at.jpg
The CPU monitor that is enabled by default has no diagnostic tasks associated to it
http://i.imgur.com/AKAKOP9.jpg
While I have the ability to create my own diagnostic task, I would rather not, as it requires me to enter my own command or script.
I liked the fact that the CPU monitor would list the top consuming processes, as this was useful troubleshooting information.
Does anyone know why this diagnostic is not included in the new version of this monitor? I cannot find any information in the release notes.
Is there any reason I should think twice about disabling the default monitor, and setting an override to enable to “legacy” monitor that has the diagnostic task built in?

I can confirm that the other OS versions have the single CPU monitor with diagnostics set to run by default. For Windows Server 2008 R2 I have created a sample management pack which enables this functionality which is available at:
http://www.systemcentercentral.com/download/re-enable-processor-diagnostic-windows-2008-management-pack/.

LMS 4.2 - CPU Utilization Reports

We have CPU reports set to run daily for some of our higher priority switches, and we've noticed that some of the data isn't meshing with what we see on the switch. We have one heavily utilized switch that reports near 100% CPU utilization sometimes. I can do a "show proc cpu history" on that switch and see that at least once an hour over 72 hours, we'll see a near 100% CPU utilization.
The problem is that these spikes never appeare on any of our reports. We'd like to see this info because even if the switch spikes for just a few seconds or a minute, it could still indicate that we may have issues. Without that in the report, we may never realize there could be a problem.
Is there a way for this info to show in the report? I'm under the impression that if LMS polls the switch and doesn't see a high utilization average, then maybe it doesnt' enter that in the report. I guess I'd just like to know how often it pulls this data, and how it decides wath the Min, Max, and Averages are.
Thanks for any help!
Tim
