CPU Consumption Problem?

Hello all,
I have a 13-inch mb aluminum with snow leopard 10.6 and had a question with a problem that I've been having recently. After doing some searching, I couldn't find anyone with the same problem.
So basically, what happens is that my computer will be working perfectly fine and the cpu will be idling at 1-3% capacity, which is what it's supposed to do when you're only checking websites/doing word processing ect. Then all of the sudden, my CPU % usage jumps to 50-60% capacity and my laptop starts getting really hot (I have smcfancontrol and it says it's 78C degrees and the fan's speed is 7000rpm). I then proceed to the activity monitor to see what program(s) are sucking the CPU power, but to no avail. All of the processes that are showing aren't taking any more than 4-5% CPU power combined. What gives? This has happened to me twice already in the past 4 days, so I feel that it'll happen again.
The quick fix is restarting my computer... But I was wondering if there's a more serious problem? Has anybody else experienced this? If so, how did you fix it? I appreciate all of your feedback. Thank you in advance!

Thank you for your help all! I do have a brother 2170w and did notice the other day that it wasn't working (the wireless part) and had to print elsewhere. So I guess snow leopard is to blame? It all makes sense now, because yeah, I did try to print something after upgrading to snow leopard to no avail.
Jay,
I did download and install the new drivers, so hopefully it'll work. I wasn't however, able to find the previous drivers while doing a search in finder (I tried brother, br, and other variations). I just downloaded the new ones and installed it... Think it'll be a problem? Computer's working fine now.

CPU consumption 100%: How do I see which SQL is consuming?

Hi,
I need help badly with this because I cannot get my head around the problem. I have a Windows server 2003 Enterprise 64-bit running Oracle 10.2.0.3 and last night it started consuming 100% CPU. The Windows performance monitor shows 100% CPU in any case, and it was difficult to even login via remote desktop.
It is Oracle.exe that is consuming, and there is only one database on this server. It is an Opteron 875 2.2Ghz with 8GB ram.
I want to see which SQL statement is responsible for the CPU consumption. I know exactly which user/programapplication is using it... it is useless to kick the session because the application connects immediately again from the app. server and runs the same thing. Restarting the database also has the same effect: session reconnects and CPU goes through the roof. Customer says that they are running the same stuff as always, and app. has not been updated recently. 100 % CPU to them, means something is wrong.
Incidently, I tried to CPU patch this database a couple of days beforehand, but there was not enough space on disk (needed 1.6GB) so opatch complained and would not continue. I simply restarted the database without having run opatch. I cannot imagine that this is the cause of this problem.
Anyhoo...
I have a script from Kyle Haileys web site to get the CPU for each sql_id using ash tables:
-- (c) Kyle Hailey 2007
col type for a10
select * from (
select
ash.SQL_ID , ash.SQL_PLAN_HASH_VALUE Plan_hash, aud.name type,
sum(decode(ash.session_state,'ON CPU',1,0)) "CPU",
sum(decode(ash.session_state,'WAITING',1,0)) -
sum(decode(ash.session_state,'WAITING', decode(wait_class, 'User I/O',1,0),0)) "WAIT" ,
sum(decode(ash.session_state,'WAITING', decode(wait_class, 'User I/O',1,0),0)) "IO" ,
sum(decode(ash.session_state,'ON CPU',1,1)) "TOTAL"
from v$active_session_history ash,
audit_actions aud
where SQL_ID is not NULL
and ash.sql_opcode=aud.action
and ash.sample_time > sysdate - &minutes /( 60*24)
group by sql_id, SQL_PLAN_HASH_VALUE , aud.name
order by sum(decode(session_state,'ON CPU',1,1)) desc
) where rownum < 10
This give following output:
SQL_ID PLAN_HASH TYPE CPU WAIT IO TOTAL
cxk376gut06wn 3831248992 SELECT 12 145 5855 6012

275bbj5czbrwp 629013258 SELECT 0 2 64 66
1dvrrg3aah2mu 75914095 SELECT 0 6 57 63
My assumption is that this gives the average CPU usage over the last x minutes and the total cpu usage for this sql_id. There are no sql running that show a very high average CPU, but the total is up in 6000 for the longest running sql, so I get the statement for the top sql_id that has highest total, and it is this:
SQL_ID cxk376gut06wn, child number 2
SELECT NVL(MIN(ID),0) FROM TABLE_OBFUSCATED WHERE TASK = :B1 AND
STATUS='JobQueue' AND MESSAGE_ID IS NULL
Plan hash value: 3831248992
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | | | 3231 (100)| |
| 1 | SORT AGGREGATE | | 1 | 42 | | |
|* 2 | TABLE ACCESS FULL| TABLE_OBFUSCATED | 3 | 126 | 3231 (1)| 00:00:39 |
Predicate Information (identified by operation id):
2 - filter(("TASK"=:B1 AND "STATUS"='JobQueue' AND "MESSAGE_ID" IS NULL))
It doesn't seem to fit! It's such a simple statement, but according to ash this is the sql using the most total cpu over the last 30 minutes?? So I create a temp index on the filter and check the plan for the statement again, and it uses the index, but I need to kill the session or bounce the database for the new plan to be used because the currently running session is still using the old plan. Customer was desperate to get it down so I even tried flushing the shared pool but new plan does not get used. I did not want to restart the database. Do I have to kill all sessions using that plan for the new one to take effect?
Now im stuck. I don't really know how else to get an accurate picture of which sql is currently consuming CPU. I need to know this to try to fix the SQL because stopping the application is not an option, even if it is throwing too much at the database. The only other option I can think of is setting up profile limits for cpu consumption in oracle, but then the job will likely take an unacceptable amount of time for the customer.
So my questions are:
1. How else can I check which SQL is using CPU accurately?
2. Does the SQL I show above accuratlely display current average CPU over x minutes with ASH? Why is it so low for the top consumer but my CPU is still at 100% on the OS?
Thankyou for your help.

Yeah, OK, I can see an arbitary number for CPU used since session startup (what does that refer to by the way? It can't be percent), and I can see that one user has consumed massive amounts of CPU compared to all other sessions, but he is currently not running anything, so how can I see which SQL he ran in the past day that cuased all that CPU consumption? Can I do this without AWR?
By the way, do you need a Diagnostic Pack license for simply viewing the Performance tab of dbconsole? I Can go into dbconsole and see history for 2 days back and see the massive espike that caused CPU consumption, but when dbconsole displays the list of top SQL and top sessions under the graph, is it the top listed SQL that consumed the most cpu or do you need to correlate the colours, i.e. find the SQL listed in top SQL that has the same colour as CPU usage on the graph (green) even if it is not listed as the top "consumer" (which I assume means top AAS consumer: overall consumption of all resources)?

Java SP - ResultSet.updateRow causes 100x CPU consumption

Oracle 11 Enterprise on Windows, with an out-of-the-box installation.
I select from a table. No where clause. No order by. If I use ResultSet.updateRow to change any column, the CPU consumption of oracle.exe jumps 100x. Here is the code.
Connection con = DriverManager.getConnection("jdbc:default:connection");
Statement stmt = con.createStatement(ResultSet.TYPE_FORWARD_ONLY, ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery("select cola,colb from tab");
while (rs.next()) {
rs.updateString(1, "qwerd"); // comment out to save 99% of your CPU*
rs.updateRow();
rs.close();
stmt.close();
con.commit();
For my test case, against 10,000 rows, removing that one line changes the CPU consumption from roughly 7 CPU seconds to 0.07 CPU seconds. I do mean CPU time - not elapsed time. The CPU measurement come from v$sesstat.value. Task manager confirms oracle.exe using 100% of a cpu for the duration of the call.
I know that this example can be replaced with a single update statement. It is a gross simplification of a much larger proc, to replicate the problem.
Help?

Hi. For each row (when really updated), the DBMS is probably having to re-iterate
through the table in the same unqualified way your query does, to position itself
to the row you want to update. This whole thing is extremely inefficient, and I
understand that you've reduced the issue to the simple example, but this does
expose the critical fault of the algorithm. It breaks the number-one performance+
rule for DBMS applications+: Don't move the data. Don't bring whole swaths of
raw rows one-by-one to the client, just to find what you want to modify. Do the
work where the data is, in the DBMS, using stored procedures. Build your saw mills
where the trees are.

Oracle10g CPU Consumption

I just upgraded one of my W2K development servers from 9.2.0.1.0 to 10.0.2.1.0. After upgrading I noticed that the CPU consumption is constantly at 50%, even though the database is completely idle. Has anyone had similar experiences? What's eating up the CPU?

This might not help you but...
I installed 10g on my WinXP desktop last year. I saw one of the Oracle processes (I don't remember if it was oracle.exe or something else) consume exactly 50% of CPU. The problem turned out to be that my firewall, which was in auto-disallow mode, was preventing something from connecting.
I started the installation over (this time with my firewall on notify mode) and during installation the firewall would popup a message about a new connection which I would allow.
Everything proceeded fine and now oracle.exe takes very little CPU when idle.
Of course, it can consume 100% when busy.

CPU consumption is quite high

Hi All,
I have created one Flash application which reads the rss
feeds from the specific url and displays the data into datagrid.
Also It has two tickers scrolling right to left. If I run the
application from flash then it works fine with CPU consumption of
around 5. But I I make exe using Macromedia Zinc 2.5 and run that
exe, CPU consumption goes to 30-40. What could be the reason.
Please any one can tell me the cause....
Thanks in Advance.............

how do you measure CPU utilisation? iostat, top, looking for LA?
if your network management system runs OK and everybody is satisfied, then you should not care much about load.
what you should do is to estimate your capacites, make a test run, to determine at what point (io, cpu) users will start to experience problems,
i suppose NMS is a vital application for your network, so you server should be able to cope with at least 30% immediate increase of load.

What does com.apple.cts.plugin do? It seems to be causing high CPU consumption by UserEventAgent

I have been having some trouble over the last couple of days with UserEventAgent process. It constantly consumes over 100% CPU. This of course results in obvious problems of the unit getting really hot, high CPU fan speed and faster battery drain.
While investigating the root cause, I removed each of the plugins (located at /System/Library/UserEventPlugins/) one by one and restarted the UserEventAgent process (if you force quit the process, it restarts) and each time, observed the impact on CPU consumption.
After a while, I was able to zero down on "com.apple.cts.plugin". If I removed this file from the plugins folder and forced UserEventAgent to restart, my CPU usage went back to normal with no excess heat or high-speed fan.
While it seems to solve my problem, I am left wondering what this plugin really does and if by not having it I am putting my system at risk.
Any help would be appreciated.

I learnt this the hard-way as well. I am not too sure but probably it has something to do with cerification authority or something like that. BTW I am looking for the answer as well.

My solution (or so I thought) to Power Manager/CPU throttling problems!!!

I have found a solution to all my Power Manager/CPU throttling problems!!! Though there is some good and bad news.
{EDIT: The problem has NOT been fixed, even after latest PowerManager (3.62) and BIOS (1.30) versions. Pretty much ignore anything I say below as the problem is still occurring. You can see my full post here: http://forum.lenovo.com/t5/W-Series-ThinkPad-Laptops/W520-Speedstep-not-working-properly-on-battery-...}
Good news: I have NONE of the throttling issues or inconsistent CPU frequency problems I was having before on AC or battery power. Everything, including TurboBoost on battery works! It is completely fixed! (I have no idea how this factors into Lenovo’s statements that TurboBoost is disabled on battery “by design”. There is at least one other post from someone else that also reported TurboBoost was working for them on battery)
Bad news: I don’t really know which one of the many things I tried actually worked. I am sorry I wasn’t more methodical about recording what I did and checking results, but this was my last ditch effort to get this fixed on my own without sending the system in for repair and frankly, I didn’t think it would work. Now that it has worked, I’m hoping my steps can help others.
For anyone interested, here’s what I did… and before anyone says something like “That has nothing to do with managing power/cpu, why would that help?!… etc., please keep in mind I’m just stating exactly what I did. I am aware some of the steps may not be relevant, but who knows… We all know how weird PC’s are sometimes, even the smallest, oddest thing may resolve a problem.So anyway, here goes.
**IMPORTANT** Not sure how many noticed, but there was a new version of Power Manager released a few weeks ago, 3.62. The PM driver seems to have stayed the same. That alone could very well be the sole fix, I’m not sure. You may just want to completely remove PM and PM driver and install the latest version before trying any of the steps below.
1)Made a complete system image via Windows built-in backup feature
2)Disable any 3rd party fan/CPU control utilities (Throttlestop, etc). Make sure they are also not going to run at startup or from a scheduled task
3)Remove Power Manager Driver, then remove Power Manager software
4)Reboot to Windows
5)Remove all traces of the Power Manager drivers/software directories (think it was something like C:\readyapps and C:\drivers.) **For some odd reason after I did this, my wireless stopped working but it resolved itself by the time I was done with these steps, strange
6)Reboot
7)Access BIOS and reset all settings to default
8)Boot into Windows, downgrade to BIOS 1.25 [UEFI: 1.25 - 8BET44WW / ECP: 1.14 8AHT32WW ] via the Windows flash utility. I wanted to downgrade all the way back to 1.06, but the software would throw up some error for any version prior to 1.25 and wouldn’t proceed
9)Reboot to Windows; make sure system booted w/ out issues
10)Reboot again, access BIOS, reset to defaults again
11)Shut down system
12)Disconnect AC power. Remove main battery. Access and disconnect system backup (a.k.a CMOS) battery under keyboard. Discharge residual power in the system (there are various ways to do this, but you could just leave the battery disconnected for a few minutes). Visually inspect the system for anything funky…my system had a slightly but noticeably loose CPU/GPU heat sink/fan assembly power connector.
13)Reconnect backup battery.
14)Reconnect AC power but leave main battery disconnected.
15)Power on. Should get a message indicating “checksum error, system time reset” or something like that.
16)Reboot to Windows. Verified still okay.
17)Downloaded latest BIOS version, 1.26. This time I burned the bootable BIOS flash CD instead of running it through Windows.
18)Restart and boot from disc, flash BIOS to 1.26. Once complete, restart. Verify BIOS set to defaults.
19)Boot back into Windows.
20)Install latest Power Manager driver (1.62 ), reboot if/as prompted. Install Power Manager (3.62), reboot as prompted.
21)Boot into Windows, verified Power Manager was active and working. Verified TurboBoost was working. Restarted system a few times and played around with Power Manager for a bit to see if the different power plans worked and retained the settings, all the while monitoring the Intel TurboBoost utility and PM’s own “power gauges”. Let system Sleep, changed power sources, resumed, etc. Everything was working great.
22)Shutdown, reconnect main battery. Booted into Windows. Again, fiddled with Power Manager for a bit, switching between power plans and AC/battery power. Still worked great.
23)Success!
That’s it. Again, this is not a guaranteed fix guide. These are just simply the steps that I took on my system that resolved the problems many of us are having. Hopefully it will work for others.

(PM driver) http://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles/83ku14ww.exe
Now, I did chipset first (didnt ask to reboot) then installed the PM driver (did ask to reboot)
I rebooted.... then I went into bios (1.26) and set everything to default... then restarted saving changes...
Since I prefer not using optimus I changed the display settings in bios right after saving the default settings...
Not sure whether or not you really had to go into bios... but everything seems to be working...
My settings in PM is set to Maximum Power in the Advanced tab, 3rd party monitoring tools is TPFanControl and HWInfo64....

Exchange server 2010 SP3 CPU consumption keep growing

Hi,
I'm using an Exchange server 2010 SP3 14.3.123.4 version.
We are currently experiencing CPU consumption growth on this server.
It appears that the msexchangerepl process could be a good candidate for this CPU overconsumption.
Any clue for this issue.

Hi,
In your posting, the MSExchangeRepl.exe process keeps increasing on the server. The Microsoft Exchange Replication service provides replication functionality for mailbox databases on Mailbox servers in a database availability group. Please check whether
there is any back up program in your Exchange server. Also confirm if there is any Anti-virus program installed in your Exchange server.
In Event Viewer, please check the event log for the MSExchangeRepl source and collect any further information for troubleshooting.

Safari CPU scheduling problems

When I open a tab but remain on the current tab, Safari grind to a halt while the background tab loads. This is NOT a CPU load problem, for I am monitoring the CPU and there is plenty (I am on a G4, so not even clumsy limits to a single core can excuse).
Things like right-clicking another link to create a new tab takes an age, as does scrolling, which often invokes the beachball. It is as if the foreground page is subordinate to the background tabs.
This is unacceptable and no excuses outside of bad programming.
Anyone else see this?
Message was edited by: Baron Munchausen

I had the Safari problem in terms of it getting hung up while loading web addresses and had to go through diagnostics every time I moved the laptop from office network to home instead of it switching automatically. How do I tell if Little Snitch is still there? I can see it in the download queue, but no where else. Also, even tho I have to switch manually to the office network and Safari is slow, at least I stay online here without Safari stopping or getting error messages, which makes me wonder if my router is messed up and contributing to problems. I have reset and unplugged my home router with no apparent effect. Sally

High cpu consumption with GRE over IPSEC

Hi all,
After applying a gre over ipsec tunnel on one of our branch office, we get high cpu consumption (average 90%).
Tunnel is applied between Cisco 2851 (C2800NM-ADVIPSERVICESK9-M), Version 12.4(24)T2, (fc2) and
Cisco CISCO2921/K9 Version 15.0(1)M3.
Config of the tunnet is as follow :
- authentication pre-share
- encryption aes 256
- hash : sha
- transform set : esp-aes esp-sha-hmac mode transport
Routing process is eigrp.
Could anyone please help me on solving this issue?

Cool, good start.
Check "show ip traffic" on both sides, it would be interesting to see what's going on.
BTW the CPU usage of top process doesn't add up to 90%, there's a possibility it's traffic rate/pattern + features (IP input and pool manager would suggest that).

High cpu consumption

Hello,
in a Confluence installation, running on cluster of WebLogic Servers 8.1.4, HP-UX, Java 1.4.2, we observe very often the app server processes keeping quite high levels of CPU consumption.
Each process can fully steadily occupy two/three CPUs or more.
We managed to isolate the threads that seem to be responsible for this, the thread stacks look like the following:
"ReplicatedCache" daemon prio=10 tid=018e5a30 nid=163 lwp_id=9303762 runnable [8ce00000..8ce00dc0]

These threads seem to be waiting to lock an object, but they are constantly in "runnable" state.
Waiting AND Runnable at the same time. Not surprisingly, the eat up CPU clocks.
Any help is appreciated.

Dear Steve,
I have checked the implementation under
http://grepcode.com/file/repo1.maven.org/maven2/xalan/xalan/2.7.1/org/apache/xml/utils/SuballocatedIntVector.java
and it seems to me that neither the class , or the method is "synchronized".
Based on my previous experience you are facing there an endless loop due to corrupted pointers in the "setElementAt" method. Same issue happens in java.util.Hashmap and other similar unprotected for concurrent "put/add" classes.
I would recomment to think how to protect the "setElementAt" that you do not fall into this issue or address to the provideer of the code for solution.
Best Regards,
Sylvia

N660 TF 2GD5 - PerfCap/GPU load/Power consumption problem

Hello,
at first, sorry for my english, I will try to do my best.
I have problem with my GPU when I play Battlefield 4. Problem occours with newest Nvidia drivers, also with beta and older drivers.
Problem is that I have huge FPS drops periodically, coming maybe every 5 minutes for 15-20 seconds, for example in BF4 it means FPS drops from 50fps to 15fps, really annoying.
It does not matter at scene complexity, it´s the same in huge battles as when I am alone looking up to the sky.
I was searching why is this happening and GPU-Z helped me to indentify PrefCap, and immediately GPU load + Power consumption going down from 100% to 40-50%
I have a screenshot, but can´t findout how connect attachment (external links are not allowed).
Could somebody explain me what is the problem and why is this happening? I am thinking about to sell my MSI graphics card and buy another one because of this, I don´t want any throtling problems because of compatibility or whatever
Is there any way how to turn it off or disable? Register, something.
Thank you

you seems to be right guys.
I undervoltaged my CPU by -0.1V, lovered Frequency to 3600MHz and problem is gone.
So, time for new PSU

High GNOME CPU consumption

For me gnome-shell+Xorg are always at 20-30%, or even more, especially when alt+tabbing between windows. This means high power consumption, laptop temperature is always high, slowness...
I don't remember this happening in 3.6, am I the only one having this problem?
00:02.1 Display controller: Intel Corporation Mobile GME965/GLE960 Integrated Graphics Controller (rev 0c)

Hmm this is getting to be more tricky. Are gnome and kde installed on the same Arch setup? They could be somehow conflicting with each other, though I don't know why; they shouldn't. I don't use gnome myself so I'm not too sure what a probable cause would be other than LLVM forcing itself to be used. Apparently you're not alone with this problem, here's a topic on the fedora forums:
http://forums.fedoraforum.org/showthread.php?t=285415
According to that, it seems the OP has intel drivers and they're not being used. Just doing a google search on "gnome high cpu usage", there's a lot of relevant results. I could look deeper into it but I figure you'd be faster at it than me at this point.
