Browser's javascript engine causing high CPU load and lost swipe events

I'm having performance issues on some websites. I think that my the javascript engine in the Playbook's javascript engine is causing high CPU usage, which means the device misses swipe gestures.
Visit: http://www.bbc.co.uk/news/world-middle-east-15814035
Once the page is loaded swipe to scroll up and down. On my device (and my friend's) it is incredibly slow. Sometimes it refuses to register any swipe events.
Now turn off javascript and reload the page. Swipe to scroll up and down. Smooth as silk!
My device is a new 16Gb with version 1.0.7.3312. Thanks

I'm having the same problem on a number of websites with my 32gb Playbook. On the same sites that I notice slow, sometimes barely responsive swipes for scrolling my wife's iPad 2 handles them with ease. Disabling javascript fixes the problem however a lot of websites including gmail requires javascript to be enabled on your browser to load. I notice the problem quite a bit when using webmail to check my gmail account which is rather frustrating because it is my only option until PB gets a native email client. My PB is running software 1.0.8.4295, but the problem was also occurring when it was running 1.0.7.

Permanent high CPU load and timeouts in communication channels

Dear Colleagues,
we've a strange issue since last week. At first we had an problem with a redirect to the cytrix online booking engine within the travel management application of our SAP NW Portal. There is a redirect.jsp file deployed in our PI system that connects to cytrix and passes the URL with session link and session cookie to our Portal. We fixed that issue by restarting the PI system.
We have a PI 7.0 stack 23 on HP-UX.
After restarting we found that we've got a very high CPU load (about 75% overall CPU, or 300% at 4 CPUs) probably caused by very frequent (3 per second) minor garbage collection runs (as seen in GC.log).
On friday we had timeouts within one of our communication channels in the PI system.
We changed the heap size from 2GB to 3GB and the new generation from 341MB to 768MB and restarted the PI system. But after a few ours the system uses 75% RAM of the CPU high CPU load and the GC runs are still the same.
This is a short excerpt of our GC.log:

Does anyone know what can cause the high load?
Is the frequency of the GC runs normal?
Can the timeouts be connected to the high CPU load?
The error ony occurs on our productive system.
I'd appriciate your help very much.
Kind regards,
Paul

hi Paul,
I believe an issue like that needs to be done onsite and not via a forum
as it probably requires doing lots of checks/tests
my suggestion would be to get a PI consultant expert with basis experience onsite or do it via OSS with SAP

High CPU load and com.apple.ImageCaptureExtension2 crash after upgrade

After upgrading my Macbook Air from Lion to Mountain Lion, the system has a very high cpu load, and the crash reporter is the process that causes thee high load. In the error log I see this entry several times per second:
17.08.12 12:58:46,011 ReportCrash[5998]: com.apple.message.domain: com.apple.crashreporter.writereport.crash
com.apple.message.signature: Image Capture Extension

com.apple.message.signature3: 03A96CBDA3C85A114383537BFC5C8999
com.apple.message.result: NO
com.apple.message.summarize: YES
I investigated a bit more and recovered, that it has something to do with the printer drivers. When I remove all printers from setting, everything is fine. As soon as I add a printer (Brother MFC 9440CN printer/scanner, printer driver provided by Mountan Lion), the crash reporter starts it's work and the error log is full of those entries.
Any suggestions?
Thanks in advance,
Marcus

I did more exploration and found the cause of this, but I don't know how to fix it:
I removed all Brother and Lexmark printer drivers and rebooted (and also tested with a virtual machine using 10.8.0 as guest os that never had any printer installed). As soon as I enter the printer settings and press the "+", the crashes begin, so it looked like the bonjour one of the printers announcing themselves via Bonjour were causing this.
When watching a picture in the preview app the same happend. We have two multi function printers in our network, the already mentioned brother printer and a Lexmark X204N. Switching off the Lexmark (which wasn't installed on my Mac) solved the problem. Switching off the printer is no solution in our office (it's our fax device and main printer), but switching off mDNS on the Lexmark also solved it. But this can only be a workaround.
Is this a known problem with Lexmark devices and Mountain Lion (it works fine with machines using Lion)? Are there any fixes known? It's just the Lexmark device announing itself via Bonjour that causes trouble, even if the driver is not installed.

VI causes high CPU load after several days of running

Hello,
I have a strange problem. I have craeted a test bench control VI and it runs on five PCs, controling five test benches. All PCs have almost the same hardware, same motherboard, same CPU, etc.
Normaly the CPU load is around 50% when I run the VI, but at one PC the CPU load climbs up to 85% after several days (maybe one week) of continuous running and the PC is almost tied up - the VI execution becomes very slow (10 times slower) and the mouse only moves very slowly.
First I thought that the PC has a problem but the problem dissapears as soon as I stop and restart the VI!
I don't even have to terminate LabVIEW - only my VI and then everything is okay again.
The problem does not seem to occur at the other four PCs, but I can not tell for sure.
The task manager says only LabVIEW causes the CPU load - swap file utilisation is little.
Is there a way to analyze what causes the high CPU load?
I Use LabVIEW 7.1 professional
Operating System: Win XP (SP 2 or 3 I don't remember)
P.S. I have no loops without wait-functions.
Greetings Johannes

Do all PCs have the same amount of RAM?
What is the memory use over time as seen by the windows taks manager. Does it increase gradually?
An increase in resource usage if often cause by sloppy programming.
Do you grow arrays forever or constantly resize arrays in memory? (built array, insert into array, delete from array)
Do you often create new references and never close them?
What does the program actually do? In my opinion, a constant 50% CPU load seems too high for my taste. It means it would not even be able to keep up on slightly older hardware.

Enabling NSX on cluster cause high CPU load

I'm testing NSX in my nested vSphere lab, when enable NSX on cluster each nested esxi starts to use 100% of 1 pCore assigned to nested ESXi.
esxtop shows that netcpa process use 100% of resource of 1 pcore.
Also I try to reproduce that situation on physical hardware, and the result was the same, netcpa uses 100% of one pcore.
Is it normal situation? Why NSX uses so much resource.

You'll have to give more details:
-is hardware on vSphere and NSX HCL?
-physical hardware specifications
-NSX version
-vSphere components installed, versions and baseline functionality (is environment falling apart or functional and super fast)
-How far have you gotten with the NSX deployment...did you fully deploy solution or stop at the host preparation step when you noticed high CPU load
-are there any other problems in environment or with host/s
-is the solution licensed properly
-have you checked the netcpa log file on the ESXi host?
-have you checked the hostd log file on the ESXi host?

Syslogd makes high CPU Load and standby mode doesn´t work.

After updating to Leopard I see high CPU Load caused by syslogd daemon(40%-80%) and my MacBook has problems with standby mode. After stopping the white LED lights and CPU fan speeds up. Is there any chance to fix these problems?

OK.. here's where I'm at with troubleshooting this. As I said before, for ME it occurred simultaneous to a low or out of memory situation. I don't know if syslogd was using my the ram, or if the low ram was a symptom of an issue that syslogd was getting caught up in reporting... but the system log file had tens of THOUSANDS of out of memory errors listed. Almost all were from dashboard.
So... I've done the following. In dashboard I closed ALL open widgets. I disabled spaces (since in another thread someone indicated it used a lot of memory). I ran Leopard Cache Cleaner and used it to perform maintenances, run the os scripts and rebuild caches and so on. Rebooted.
Now its working fine! Since then its been over 24 hrs and I STILL have over 300megs of ram reported free on a 1 gig system. I've used everything else like normal (safari, mail, ichat, itunes, etc..). Where the problem used to happen after a couple of hours after a reboot every time, now it seems normal. No out of mem, and syslogd is running normally (apparently).
I will run a few apps that I havent run in a while and see if those create an issue. If not, later today I will enable spaces and see how that does after a few hours. Finally I'll add in the dashboard widgets one at a time to see if the issue lies there. I'll report back here if I discover anything.

TouchPad driver: relatively high CPU load and loads of registry accesses

Under Vista 32 SP1 with the current UltraNav drivers (v 9.1.3.7) the process "SynTPEnh.exe" is creating a relatively high CPU load (2%) and is constantly accessing the registry. See here for a typical pattern creating by Process Monitor:

Can this driver be optimized?
Also, when I use the TrackPoint to scroll in Firefox or in other applications, scrolling is not as smooth as when I use a simple external mouse with a wheel. Moreover, while scrolling with the TrackPoint, the "scrolling cursor" flickers.

OSX Lion QuickTime Internet Plug-In causes high CPU load

I have OSX Lion installed.
Now I have a CPU load between 80 to 130% caused by the Quicktime internet plug-in if I watch my ip-camera with Safari. Also I get no Audio out of my ip-camera anymore. In SnowLeopard everything was fine, Safari CPU load at 30%. What is wrong ? Can anybody help me ? It is an Y-Cam Knight SD and a MacMini core 2 Duo.
Karsten Preussner from GERMANY

I had this same problem and couldn't get it to work at all. I tried to install the 3IVX plugin listed here and it didn't do anything. So I uninstalled it.
Then I thought to try my Macbook Pro and see if it was working on that computer, sure enough it was. I checked the HD/Library/Quicktime folder and it only had 4 items in it, whereas on the Mac Pro (that was not working) had 19 itmes in there. So, I moved all 19 out to a new folder and copied only the ones that were in the MBP. When I opened Safari IT WORKED!!! NO MORE PLUGIN FAILURE.
So, I must have just had too many old things in the quicktime folder that was causing it to fail.
Here is a screenshot of my HD/Library/Quicktime folder contents. The top folder shows the 4 items that should be in there (Perian is optional) and the bottom window in the screenshot shows all the stuff I previously had in there which caused the failure.
So If you are having this plugin failure, try removing all but these essentials from your HD/Library/Quicktime folder. It worked for me!

Persistent Active Requests causing high CPU usage and load average

Hi, we've deployed a JSP application on standalone OC4J talking to Oracle DB. The whole thing runs on Sun Solaris. On some occasions (still investigating what causes this), the number of active requests rises (as seen from EM console) and never drops down. The weird thing is, the load average numbers are proportional to the number of persistent active request. If there are 3 active requests, load avg will be [3.x 3.x 3.x], and whenever persistent active request exist, CPU usage will shoot up to over 90% (usually between 95% - 100%). When the system is running normally, CPU usage is usually less than 20%. Is it possible to track down this problem and how? Many thanks.

Welcome to Apple Discussions!!
The icons on the right of the menu bar … show a beachball when I put the cursor over themWell, if this was your only problem I would put it down to a corrupt preference or cache file. Nevertheless, it is worth seeing how much this helps.
The file you need to trash is 'systemuiserver.plist'. But there are potentially two of them, plus it is best to delete your caches as well, so ...
In "/Users/<yourname>/Library/Caches", delete everything
In "/Users/<yourname>/Library/Preferences", delete com.apple.systemuiserver.plist
In "/Users/<yourname>/Library/Preferences/ByHost", delete com.apple.systemuiserver.xxx.plist where 'xxx' is a 12 digit (hexadecimal) numeric string.
See if this improves the situation, and post back with any remaining oddities.

What does the 'rtcli async executor process' process do on a Cisco ASA and why would it cause high CPU load?

I noticed that the CPU on our ASA had jumped from around %4 to 30% consistently a few weeks back. The process below seems to be causing the load, but I can't find any information on what it does and how to resolve the issue.
ASA# sh proc cpu-usage sorted non-zero
PC Thread 5Sec 1Min 5Min Process
0x08a24505 0x1bdb0124 25.4% 25.6% 25.6% rtcli async executor process

0x0866d56e 0x1bdafd1c 0.1% 0.1% 0.1% ARP Thread
A little more background that has me concerned is that I have the exact time when the jump occurred. Since that time, I've lost ssh access to the ASA and can only access it via Telnet internally or the ASDM. I checked the certificates and a new one was generated exactly when the spike occurred. I am unsure wether or not that was a system triggered certificate generation, or if I have a security issue I need to address. Heartbleed maybe??
Any insight would be greatly appreciated.

Sorry I wasn't clear, but when I was asking about "not a lot of traffic", I was wondering about actual volume passing through the 2811.
When I asked about "kind of tunnels", I was wondering about how they are configured. E.g. GRE or IPSec/GRE or VTI, encryption options, other tunnel interface options.
Perhaps the easiest way to check for fragmentation, is packet analyze the traffic passing through the 2811.

Eclipse causes high cpu load after firefox update

Hi,
I have a strange problem after the latest firefox (and xulrunner) update (3.0.5.1 and 1.9.0.5-1). When I open firefox and afterwards eclipse, eclipse uses about 60% of the cpu after a short while; even if I don't do anything at all (and nothing gets compiled) in eclipse. But when I open firefox and eclipse in the reverse order, eclipse behaves normally again (like before the update).
After a downgrade to xulrunner-1.9.0.4-1 and firefox-3.0.4-1 the execution order of both programms is irrelevant again.
I assume this has something to do with java or maybe xulrunner?
Thanks, for any help.

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Flash causes very high CPU load (including high Xorg load)

Hello everybody,
this is my first message. I'm an Arch user since a few months, and I'm pretty sure this is the distribution I'll stick to - I pratically love everything about it, especially its simpleness. It's the first Linux that doesn't scare me away with tons of configuration files scattered around dozens of different locations. I've already gotten quite a number of things fixed by myself without even looking at the forum or wiki.
Well, it seems most of these statements can be found in most first forum posts, so I'll stop to bore you...
The problem: Playing flash videos or animations causes incredible processor load: Even youtube takes a whole CPU core (or even a little more), top shows around 80% for Xorg and around 20-30% for Firefox (a little less with Opera). I'm on Arch64 with XFCE, Athlon X2 4600+, NVidia 8200 chipset (which has severe driver problems anyway; I'm using the latest NVidia beta driver). I'd try the open source nvidia driver, but (it seems that) there's no support for my chipset yet.
Currently I'm using Adobe's Flash64 alpha, before that I used various versions fo the nspluginwrapper. 32-bit Flash also caused high CPU load, but it wasn't that much and it may have been related to nspluginwrapper rather than anything else; however I have got the impression that things became even worse with the switch to the x64 alpha (performance-wise; on the other hand, it at least loads faster and doesn't crash anymore). Like said before, youtube takes one core, but it mostly works ok then, but videos with higher resolutions that youtube's are practically impossible to watch (except when there is very little movement in the film). Neither Flash hardware acceleration on nor off makes any difference.
I've already read half of the web, searched in forums, wikis, etc., but didn't find anybody with the same problem. When Flash64 was released and people were reporting good improvements, I was hoping it would be the same for me...
What I'm looking for is suggestions of things to try... I'm out of ideas what to try and where to look. It just seems strange that I seem to have problems that others don't...
Thanks for reading and for any comments.

DMVPN phase 3 - scalability - nhrp generates high cpu load

Hey all.
Been running into a scalability issues with DMVPN. Mainly caused (as I see it) by NHRP.
Scenario:
IOS-SLB-based DMVPN solution in a dual-cloud setup. Practically it's 2 separate solutions with spokes having 2 tunnels (one in each cloud). See attachment sketch. We're running a phase 3 hierarchy design (trying at least)
Spoke routers:
- 2500 routers in a mixture of c871, c881, c2800, c2900. Need to scale to at least twice that.
- Spoke-to-spoke is heavily used
Farm routers:
- Cisco 7201 with VAM2+. Around 1 router per 350 spokes (+1 for secondary tunnel)
Superhub:
- ASR 1004 (one for primary and one for secondary dmvpn-cloud).
We're not running any IPSEC between the farms and the superhubs. Just regular unencrypted DMVPN (mGRE).
Problem:
- NHRP is causing high CPU load on the ASRs. With around 2000 spokes up and running on DMVPN the CPU is overloaded with NHRP traffic. We're talking like 60-70% load caused by the NHRP process alone!
We're using 'ip nhrp interest' on all the spokes - and farms. We're in need of the spoke-to-spoke functionality so we allowing LAN-segments of our customers but denying everything else.
Solutions?
1. Turning off all NHRP resolutions? Basically remove any directly spoke-spoke communications (denying everything on the interest list). We can't go there since a lot of our customers are in dire need for directly spoke-spoke connectivity (due to latency). Haven't tested that it will actually give the much needed scalable solution either (we're facing around 5000 spokes in the next 2-3 years).
2. Chopping the DMVPN solution up in lesser VPN-blocks. This will administratively be a nightmare.
3. ?
Will really appreciate if anyone have a input here. It's really hard finding anything about a LARGE scale phase3 design on the web. Everything I find seems to mix stuff from small-scale phase 2 and 3 - making it rather messy cooking reciept for a small breakfast while I need a 7 course perfect dinner
When will Cisco come with an updated design guide btw?
Thanks in advance!

Thank you for your quick reply.
Our ASRs (rp1) are acting as BGP RR while the farm routers are setup as RR clients.
We haven't tried connecting spokes directly to the ASRs but we have seen the same symptoms on the 7613s (sup720) and the 7200-platform.
Earlier the 7600 had the same role the ASRs have today. We were expecting that the ASRs should be doing "a better job" in terms of CPU load but we were wrong (NHRP generated around 10% more cpu load on the ASRs in comparison).
We concluded that the ASRs have a less optimized OS (coding) being rather new and all. Further we're not all happy about the stability of the platform (clear ip nhrp or taking a shutdown on the tunnel in the current situation will crash the router. 15.1(2)S1 and 15.1(3)S0a adv ip services). Haven't made a TAC case of it yet but will (has to be a bug as I see it since the 7200/7600 is handling this just fine).
Due to what I mentioned above I don't dare to debug the problem in production time and have to wait until the next scheduled maintenance window for some decent debug output (24. Oct).
We've contacted Cisco AS for assistance since it's hard to find local consultants (Norway) with enough knowledge of such scenario.
I just hope it's a config-issue and not a design issue, but we're willing to to whatever for this to scale to the thousands.

Isa 2006 wspsrv.exe high cpu load

I have an ISA 2006 Server which run for 5 years without any problem. As the hardware is getting old now I have decided to change the Hardware to a new server but was unable due to the hardware to install Server 2003 which ISA runs only on this one as it
is 32-bit. I then decided to install server 2008 R2 and install isa 2006 on a vm. Installed all updates patches on server 2008 and the 2003 running on VM, SP1 for ISA.
Everything went fine, transferred the rules and Exchange and everything works fine. However, every day, two days three days, very randomly and no systematically timeframe isa 2006 wspsrv.exe get a 99% high cpu load and then the service makes
the internet to stop. No internet access anymore, no ping by name or IP. Rebooting the server fixes that problem until it happens again. It also happens during different time when people are working or even during the weekend when noone is
working on the system.
I have no idea anymore what I could do next. ISA is the only thing installed on the Server
Any help would be appreciated

Hi,
The blog analyzed a scenario that the high CPU is caused by the third party driver. You could refer to the steps in the blog to troubleshoot this issue.
Quote:
What we can conclude here is that we have a condition where wspsrv.exe was allocating more and more threads without releasing resources (releasing threads) because it was getting stuck waiting for an answer from kernel driver.
Some threads were working on I/O, mainly socket and LRPC call (almost socket) that run in Kernel mode. The third party driver is causing every AFD call to take more time and more CPU cycles, the fact that ISA is extremely using sockets amplify the problem.
The third party kernel driver was uninstalled from ISA Server and the issue was resolved.

Kernel task over 100%. High CPU Load. High Temp. Problem Solved.

Hi,
I thought i would make a post as i had been having trouble with my 13 inch mid 2009 MBP for sometime (6 months), with runaway kernel tasks causing high CPU loads. I had searched through forums and discussions for a long time trying to find the problem and isolate it. Initially i discovered some problems with finder preferances that were chewing up CPU which i solved by deleting the prefereance file, allowing the system to recreate a non corrupted version. This helped but still i had problems. I tried maintainance suites like onyx, reseting PRAM, booting into safe mode, hardware checks and diagnostics, and more little tricks than i can remember. Nothing i tried really seemed to make a differance. Through reading on this forum and others i found out the kernel tasks can be a direct result of hi CPU core temps as the system runs a lot of small kernel tasks to try and take some of the CPU load away from processor intensive processes that may be contributing to hi CPU load. The thing which solved my problem in the end was opening up my MBP, being careful not to touch the logic board and literally puting my vacuum cleaner over the fan, sucking dust and dirt and dust out of my latop. This computer has been through the dirt with me, literally its been dragged through rural south east asia for a year and accompianied me to warhouse parties to perform and run lighting and visuals. Its little wonder the fan was obviously clogged. I know people tend to be holier than though with their mac products and treat them with the upmost respect, but my love for the MBP has come from how sturdy and reliable it has been under less than desirable conditions.
Now im not telling people this is what they should do, i had just noticed alot of people with this problem in my attempts to solve mine, and in the end this is what helped. My MBP now runs at a temperature where i can touch the metal near the CPU without being worried about a 3rd degree burn and the CPU load is acceptable with no run away kernel tasks. Like i saw this might not be the cause of your porblem, as my laptop has lived a rough and fun life so far, but i thought i would share this with you all as i have had contstant help from this forum and others searches for solutions to problems with my apple products.

Already tried SMC and PRAM-reset with no luck.
On my MacBook late 2008 it's the same effect.
