XMLReader.parse causing 100% cpu

Hi
My Code looks like this:
InputSource inputsource = new InputSource(new StringReader(file);
System.out.println("V5");
reader.parse(inputsource);
System.out.println("v4");
"file" is an XML file from an engine that is of huge size. Around 7MB
The problem is V5 is getting printed.
And then cpu reaches 100% , and i never see v4 atall.
Would any one be able to give some inputs although my explanation doesnt look suffecient.
Thanks
Raam

nothing seems odd about that, except perhaps that it never ends. Try bumping your memory size up and try again
java -Xmx768m .....

Some web pages causing 100% CPU use of iexplore.exe since Flash update

I'm having a problem with certain Amazon.com pages hanging my
Internet Explorer 6 using Flash Player 10,0,12,36, causing 100% CPU
use for iexplore.exe and requiring me to End Task to quit. All the
pages effected have an interactive mouseover Size and Color chart
that intially says "Loading" but then says "Select Size and Color"
once loaded. One mouseovers the various color patches and size
options, each time giving item availability in that option. When
the pages hang the IE browser with 100% CPU use that chart never
gets to the "Select Size and Color" point, instead stuck at the
"Loading" status. This happens most times, but not every time.
Sometimes the pages load correctly, after a brief lag as it loads
the chart.
Amazon pages without this chart load fine.
The start of this problem coincides with updating Flash.
I can prevent the problem from happening almost every time if
I can quickly get my cursor into that chart area while the page
begins loading. If I allow the pages to load fully with no
interaction they will hang almost every time.
I have not noticed any problems on those same web pages using
Firefox using Flash Player 9,0,124,0
I also have not noticed any issues with other sites using
Internet Explorer either. (YouTube, QVC, CNN...etc, all OK.)
I had posted for assistance on the Experts Exchange site and
there was some debate on whether the chart was a Java or
Flash-based chart, so initially it was being approached as a
possible Java issue, so I removed all Java versions on the system
and installed various versions, but the same problem persists.
I've downloaded but not run the Flash Uninstaller, as I'm
reluctant to uninstall the Firefox Flash version without knowing
for sure I could install 9,0,124,0 again.
I've downloaded an archived fp9_archive.zip, which seems to
indicate the contained files flashplayer9r124_winax.exe (Internet
Explorer) and flashplayer9r124_win.exe (Netscape) would be versions
9,0,124,0 to install after running the uninstaller.
Can anyone check a few of the links below and see if the
"Select Size and Color" chart is Flash based? If so, would
executing the files listed above install 9,0,124,0 into my
respective browsers again?

I'm attempting to troubleshoot an issue with Amazon web pages
since I've updated my Flash player. I would appreciate if someone
could take a look at my initial post and advise if the issue seems
to be Flash related.
Thank you.

Small Acrobat file causes 100% cpu usage with v. 7.09

Using Acrobat professional 7.09
I have a small acrobat file (94k) that causes my cpu to peg at 100% I used acrobat professional to convert an eps file to a pdf file. Is there a general known issue that could be causing this?
Stephen

> Looking at the plot, you might want to consider trying to use a vector graphic in the future. It looks like a plot that you may have created in MATLAB or such. In that case, why not just print to the PDF.
I used matplotlib, which can generate png, eps, svg, or even pdf files. The pdf in question was converted by acrobat from eps, which has worked well for me in the past. I wish acrobat pro 7 could handle svg.

Recently FireFox often has been causing 100% CPU usage and locks up until it finishes the process (various ones). Clearing cookies/cache didn't help. Any ideas?

Windows 2000 SP4, 1g RAM, Firefox 9.0.1
We keep IE6 and Firefox open simultaneously for 2 different mail accounts. Firefox was always much faster even with 3 or 4 tabs open, but for the past couple of weeks when trying to update a screen the CPU suddenly goes to 100% usage and of course nothing will move until the particular process is finished. Closing one or more tabs does not help. If I close Firefox completely with Task Manager CPU usage goes back down to nil. After restarting Firefox CPU usage may or may not go back up depending upon whether it tries to continue the previous task that was locking it up.
It did not do this with Firefox 3.6 but then again it didn't happen immediately after updating to 9.0.1 either.

100% CPU usage occurred most often toward the end of the working day when busy trying to print on-line postage. We don't have any memory-consuming plugins but according to the knowledge base articles Firefox memory usage can gradually increase during the day even if you do nothing. It seems that may be the problem so we close and restart Firefox more often now as that usually fixes the problem. However, if we get stuck on a particular website update that causes the CPU to to go 100%, we can always start Firefox without previous tabs so the update will stop, or simply use a different browser until we have time to let the computer play games with itself.
So our workaround of restarting Firefox turns out to be the final solution (until we find something better - will post it if we do). Vic

BT stack file TosBTMng.Exe causes 100% CPU Load

I'm also facing the problem that the Toshiba Bluetooth Manager (TosBtMng.exe) very often starts looping and causes a CPU load of 100%.
This happened with older versions of the Toshiba Bluetooth Stack and current version (5.1.0.12).
The affected system is a Tecra S1, internal BT-Modul and Windows XP SP2.
Installation of the BT-Stack went well and the notebook will boot succesfull while BT is enabled. I also checked for hidden COM-Ports and other hints found in this forum, no success.
The lockup seems to happen at different times. Sometimes just after are reboot, clicking on the BT Tray symbol with the right mouse button. Then the context menu is shown just as white area, no entries. It may also trying to connect to an already paired device. If I kill the process with the task manager I can restart and it continues to work for some time.
As found in another thread here I have enabled API logging of the Bluetooth Manager and found the following while connecting with the Nokia PC Suite to my mobile Phone:

A new COM port is successfully created (COM23), and a few seconds later the CPU Load of TosBtMng goes up to 100%, but no API calls are performed. And if you wait long enough the phone gets connected and data can be transferred. However, very slowly.
Probably due to the high CPU load a next COM (COM24) port will be created sometime later and this process is then repeated again:

Maybe this helps to locate the origin of the CPU load problem of the Bluetooth Manager.
Thanks

I was having the same problem, and it turned out to be the Data execution prevention settings. I had turned on (System->Advanced->Data execution protection) the execution prevention for all programs, causing TosBTMng.exe to max out one processor core all the time. The solution was to add TosBtMng.exe to the list of exceptions and restart. I'd looked high and low for a solution - hope this helps someone else!

Copying from USB NTFS device with Dolphin (KDE) causes 100% CPU usage

I am copying +/- 30 GB of Music files (flac) from my external USB HDD which is formatted as NTFS.
I have installed ntfs-3g and am experiencing near 100% CPU usage. What's wrong?
Additional info: I am using KDE and initiated the copying through dolphin. KDE's system monitor only shows CPU usage near 100%, but no processes in the process view could be responsable.
Thanks!

What mount options are used for that ntfs drive?
Edit: There are many similar threads but I couldn't find a solution other than trying out some kernel and cpufrequtils fun.

[10.1.2] Protected Mode causing 100% CPU Usage/Extra Processes on Win XP 32-bit?

Hello,
I'm not 100% sure if the two are related, but I have a client who was seeing 100% CPU usage using Adobe Acrobat Reader X 10.1.2 on Windows XP 32-bit and Firefox 11. The acrord32.exe process would hang around after closing the main window and eventually leading to tons of processes and his CPU at 100% use. I believe disabling Protected Mode may have solved this issue. I didn't see it documented anywhere so I figure I'd post about it here and see if anyone else was seeing this resolved as well.

I noticed 'only' 50 % CPU usage. Not during Reader usage with ~ 20 %, but it started after closing main window.
Two instances of acrord32.exe were created - the moment pdf was opened - of which one was using zero CPU.
After opening another pdf, 2 more processes were created, so 4 in total. Have seen 2 of them using 100 %.
Issue is easily recreated.
This is all in 10.1.3, no fix from Adobe, only THE fix from you: turning of Protected Mode!
After which now only one proces is created, with 1 to 3 pdf documents opened at same time.
This instance is then nicely shutdown after the last pfd is closed.

This is the second %100 cpu utilization message I see in less than 24 hours.
I recommend you start with the basics, and learn about about paint() repaint() logic, if you have to wonder why calling repaint() is not necessary inside of paint() you need to learn the basics first.

Spreadsheet functions causing 100% CPU usage

Running ColdFusion Enterprise 9,0,0,251028 with JVM 1.6.0_14 on a Windows 2003 server. I am finding that when using <cfspreadsheet> and the spreadsheet functions to build a spreadsheet the server CPU maxes out at 100% while the spreadsheet object is being built. The spreadsheet is not overly large or complex: 10-15 columns and 400-500 rows. This behavior is consistent - it happens every time, even when building a simple spreadsheet with 1 column and a few rows. Is anyone else experiencing this? Is it a known problem with a fix? Thank you.

I was able to root cause the excessive CPU usage to a single-CPU virtual machine. When I ran the same code on dual-CPU virtual machines the CPU usage went to 50-60% but never reached 100% and stayed there as it does on the single-CPU virtual machine. So there appears to be an issue with JRun and Apache POI on single-CPU machines. I simply had my system administrator add another CPU to the virtual machine and the problem no longer occurs.

Adobe Reader 9.4-1 cause 100% CPU load on EL40 system

Hi,
when starting Adobe reader 9.4-1 on a Enterprise Linux 4 system the cpu load directly goes up to 100%
This happens on EL40 update 4, 5 & 8
I´m using gnome.
uname -a
Linux 2.6.9-89.0.0.0.1.ELsmp #1 SMP Tue May 19 04:23:49 EDT 2009 i686 i686 i386 GNU/Linux
cat /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 8)
Kind regards

I had the same problem on a RHEL4 system, I think starting with 9.3.1. The system requirements say only RHEL 5 is supported so I just uninstalled 9.3 and didn't look into it further.

SQL query against ConfigMgr DB causing 100% cpu usage on SQL server throughout day

Hi, I am hoping someone here may have an idea of what I can do to resolve this as I am not much of a SQL guy. Here is what I know. Throughout the day, monday-friday, my ConfigMgr SQL server sits at 98-100% processor usage.
Using the following query I have narrowed down the culprit of the high cpu usage throughout the day:
SELECT p.spid, p.status, p.hostname, p.loginame, p.cpu, r.start_time, r.command,
p.program_name, text
FROM sys.dm_exec_requests AS r,
master.dbo.sysprocesses AS p
CROSS APPLY sys.dm_exec_sql_text(p.sql_handle)
WHERE p.status NOT IN ('sleeping', 'background')
AND r.session_id = p.spid
Even though my knowledge of SQL is light, I believe the following output clearly defines the thread responsible for the high cpu usage. This "program_name" is present throughout the day and as long as its there, cpu usage remains at or near 100%:
The text output of the above culprit is as follows (sorry this is long):

If anyone has any experience with this issue or anything similar and might be able to point me in the right direction, any responses would be greatly appreciated. Thanks for reading!

Normally, this summary job every few mins which only summarize last few mins sending history. If the job was not running for long time, the first time, this sproc will summarize a lot more data than normal. So it could fail which will make things worse and
worse over time.
If sending summary data is not a big concern here, you can manually insert a dummy row with most recent time as Summarizationtime, so that, when summary job kicks in next time, it will only summary short interval data.
DrsSendHistory is that the table records every sending on every group. This table is one of the key of replication logic. For your environment, on primary site, it could have up to 24(hrs) * 60 (mins) / 2 (sync interval) * 36(secondary sites) records per
day for Secondary_Site_Replication_Configuration group and 24 * 60 / 5 * 22 records for Secondary Site Data.
Umair Khan | http://blogs.technet.com/umairkhan
Hi Umair,
Thank you for the reply. My plan was to go ahead with your suggestions but what I tried first was to get my VM guy to give the SQL server access to more CPU resources. We had already configured it with what would have seemed to be plenty, as per Microsoft's
sizing requirements, but I figured it couldn't hurt to rule out - he gave the SQL server access to a huge portion of the host processing power and since then CPU usage on the server has NOT been an issue.
It would appear that the large amounts of secondary sites we have just simply put a lot of stress on the SQL server with out of the box replication settings. Since the entire VM host is for System Center only, and our other System Center servers are using
very little resources, this solution has ended up being valid.
Thanks again for everyone's help with this.

Large-scale swf causes 100% CPU usage

Hi,
I've created an interactive map that loads data from XML. The
map is made from several areas (MCs, currently 16) - all positioned
in a "mega MC" that holds the map together. The JPG are loaded
externally respectively to the area MC that it belongs to.
The problem is that the Map MC (that contains all the area
MCs) is too big (around 6000X6000 Pxs) and therefore slows down the
computer significantly (The CPU reaches 100% usage). This happens
also when there's no loading of the external JPGs - meaning, I
think, that the problem is only with the "physical" size of the MC
and not its actual MB size.
I hope I was clear enough.. Would appreciate any help!
Link to map

Hi,
I had a similar problem when I needed a really big area. I
think the cpu usage wasn't that bad in Flash Player 7 and 8.5 (now
9), but in Flash 8 it was really high. I decided to not move the
big MC around, only the smaller parts that where needed. I guess
the whole map is never shown completely, only parts of it, so you
can write a scroll function that determines the active MCs and only
moves those around instead of the big holder MC. To achieve this, I
added a variable to each MC that holds the position of that part in
the big MC. Then I kept track of the position of the display in the
map, and used this to decide which parts are actually displayed.
Only these MCs have to be moved when scrolling, reducing the cpu
usage a lot. When a part moves out of the display, I set its real
position to -5000, and when a new part comes into display, its
position is set from -5000 to the proper _x value so it gets
displayed.

Tab selection property causing 100% CPU usage

Hi,
I've having some trouble with using property nodes to tab selection. After 1-2 hours the CPU usage is 100%. The VI is attached. I'm using LV 6.0.2 on win2000. Does anyone have a clue of what's happening?
Attachments:

Every time the while loop executes, you open *new* pages reference array. Whitout closing them, you quickly fill the memory and hog the computer usage. As in the modified VI attached, get the references only once outside the while loop and reuse them. Close any reference after use. As much as possible, you shoud use the control terminal to read its value instead of reading the value property.

Grid Control Perl Scripts Causing 100% CPU

I have a Grid installation on a cluster of three databases. It periodically shows that the CPU is at 100%. When I check, it is a number of Perl scripts that are executed by the agent.
Killing the Perl scripts returns CPU usage back to normal. The operating system is Red Hat, and the databases and clusterware Oracle 10.2.0.4.
Anyone have experience with this. I've looked on Metalink, but haven't seen anything.
Thanks,
John

I nearly fell off my chair laughing at the ludicrous suggestion of bouncing the box!!!
When you say: Grid installation on a cluster of three databases
What do you mean?!
Grid control monitoring 3 rac databases?
Grid control with a rac database as its repository?
Version of Grid control?!

Bluetooth process causes 100% CPU

Hi,
After installing Toshiba BT stack my CPU usage is 100%.
It seams like the process TosOBEX is the one consuming most of it.
How can I solve this?
Thanks!
/Tommy

So your OBEX COM ports are not installed. This explains your problems. I would try the following:
Download the latest Toshiba Bluetooth stack (URL mentioned above). Confirm all questions during the installation and uninstallation process with "yes" so that it will be completely removed.
Check after the installation if you see COM ports 15-19. Now use the Bluetooth stack which was delivered with your USB adapter and install it again. Confirm all questions during the uninstallation and installation process with "yes". Check if if your can see COM ports 10-14 after the installation.
