High CPU from w3wp.exe process
We are running custom code on SharePoint 2013 and are experiencing very high CPU related to a w3wp.exe process. We have run a debug diagnostic report. The question I have is, can Microsoft help us narrow down the problem through a paid
support incident or will they just ignore it due to the custom code?
If it resolves it for about 20 minutes, then it sounds very likely that it is some kind of timer job that has gone bad. Check the logs and the what is listed in the timer history listing in CA.
Depending on your App Pool settings it may keep a hold on memory.
I will refer below two links for debugging you

High load and high CPU caused by perl process
Using: Oracle 10.2.0.1.0
OS: Red Hat ES 4
Since this morning I have high load on one of my prod database server, this server has 3 databases of similar size.
High load is caused by perl process, one process has been running for over 75 min’s. process info
14302 ? R 74:50 /opt/oracle/product/10.2.0/perl/bin/perl /opt/oracle/product/10.2.0/sysman/admin/scripts/segAdv.pl
26530 ? R 23:36 /opt/oracle/product/10.2.0/perl/bin/perl /opt/oracle/product/10.2.0/sysman/admin/scripts/segAdv.pl
31152 ? R 7:58 /opt/oracle/product/10.2.0/perl/bin/perl /opt/oracle/product/10.2.0/sysman/admin/scripts/segAdv.plSearching segAdv.pl on google, Metalink and this forum gives me ZERO results.
Any idea why this is running and cuasing this issue now (for last 8 months, I had not simlar perl issue), can I stop it without kill –9, maybe with emctl stop dbconsole.
Thanks in advance for any help.Hi Lee,
You say this is a core router, but as people use this terms to mean different things, are there any directly connected hosts? If there are one thing to check for is hosts sending multicast traffic with TTL=1. If you run the command show ip traffic | in bad hop and look at the rate the "bad hop count" is increasing. If I had a £ for every time I've seen that problem.... I couldn't retire just yet, but at least I could go buy myself a beer or two.
If you're seeing the hop count increasing at a rapid rate there are a couple of options:
Take a read of Troubleshooting high CPU on a 6500 with sup720 starting from the section Tools used to determine the source of the traffic and identify the hosts sending multicast with TTL=1.
If the Catalyst 6500 use PFC 3B add the command mls rate-limit all ttl-failure 100 10 to drop the multicast traffic in hardware.
The first option will take you longer, but at least you identify the cause and can advise the application owner why they should change their applications behaviour.

High CPU usage for SERVER0 process in XI
Hi,
SERVER0 process is taking high CPU usage, previously it happen once its due to communication channel error, So we deativated some unwanted communication channels in Alert config and the CPU usage is reduced.
After some weeks its again CPU usage is increasing for SERVER0 process in some time.
Can anyone help in this case.
Thank you,
gopi.Hi Gopi,
Check out Tim's reply and check for ur Java stack settings,

Mark Greene in "On the Beach" -
I know this question has been asked a lot, but I haven't really been able to find a definitive guide.
We are running SharePoint 2013 March CU on a Windows 2012 box (24 GB RAM). We have a web application that "randomly" causes our CPU usage on the server to spike at 99%. Unfortunately, it doesn't correct itself until we recycle the application pool
in question. What's interesting is that end users don't really notice a performance hit. However, if we want to do things in Central Administration it creates havoc on the rest of our web applications on the box ultimately causing everything to time
out.
I've narrowed the issue down to a particular application pool. Per Microsoft's best practice, this application pool only has one web application associated with it. I am trying to figure out the root cause of the issue and was wondering if I could get some
suggestions or guidance on what I can do from here. I have Process Monitor installed on the server and can trace the PID, however, I am having a hard time figuring out how to narrow down the results.
We do have a custom farm solution that I believe to be the issue, however, I have no way of definitively saying that this is the issue.
There are some other PowerShell scripts that are not disposing of objects properly and I have contacted each script owner to modify their scripts to correct that issue. With that said, I ran each script individually and they didn't cause the CPU to spike
(even when they didn't dispose of the objects properly).
Any help or guidance would be greatly appreciated.is it single server farm or whats the role of the server in farm?
also things to check / monitor if this start during the Search Crawl or Profile Snyc or Web Analytics.
easy way( not easy) is use the DebugDiag tool to investigate which stuff cause the issue.

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. -
DNS server process, high CPU usage
Hello,
I am having a problem with high CPU usage on DNS process. We have 1921 setup in network of about 100 workstations that use it as DNS server. It also performs split view functionality for couple of domains in order to avoid hairpin NAT. I know that a router is not fit for heavy server duty but such setup was unfortunately necessary.
In peak work hours we oftenly have CPU hitting 100% with DNS server process being the root cause,and on several occasions we had DNS process stuck in such state for prolonged periods of time during which other router functions were affected (t's a default gateway, IPsec concentrator etc.). Sometimes shutting the process and restarting it would solve the problem, but once it required a full reload in order to restore functionality (such was the description that engineer on duty reported to me).
Forwarder queue statistics:
Current size = 0
Maximum size = 86
Drops = 0
IOS upgrade did not help, we are currently running 15.2(2)T.
The question is ... is such behaviour (CPU load) to be expected on LAN with 100 workstations due to slow CPU on router or we have bugged IOS DNS server (requiring a TAC case)?
The previous solution seem to do this functionality quite nicely (even though it was also a router), so I am not inclined to think that we are dealing with someone DoS-ing the DNS (WAN access to DNS is of course forbidden)
P.S.
Since we moved servers off the routers DNS, we do not receive complaints, but we had a couple of unresolved messages a day while mail server was using router for DNS. I am suspecting that an old bug where IOS DNS servers occasionaly sends clients back empty DNS replies (properly formatted message but without A record) could be still around?hi,
i have the same problem on UC540 and 2911 on IOS 15.0.1. CPU high, router crashed. Reboot helps but until CPU usage spikes again. the only fix is to remove "ip dns server" from config and use a different DNS server

Hi,
I'm running tomcat on Solaris 10 and (assumingly) because of higher traffic on our website, the tomcat process is taking all the CPU. How can i figure out what's causing the high CPU within my tomcat process, is there any way to extract this info, like perhaps narrowing down which thread(s) are getting most of the CPU?
Our applications are all Java servlets.
Thank you,
CharlesBut DTrace would simply show me stack information on the tomcat process wouldn't it? I guess that's all i could do though given that i don't know the internal workings of Tomcat.
Thanks,

High number of threads and high CPU usage on a single instance
Without any apparent reason, in some moments of day the website reports an increment of the HTTP Queue Length from an average of 10/20 queued requests to 100/200 and more.
In that period of time the Average Response Time increases but the number of the requests on the website don't. Even increasing the instances it doesn't help to resolve the problem (maybe it just reduced it).
It seems that the problem is not related to the traffic on the site. This issue happens either when the traffic is high or low.
The autoscaling works well, we don't have peak of traffic but always a slow increasing of requests and the CPU is always below the 50% (memory too). The issue is resolved by the swap of the site and sometimes it's resolve by itself after a while.
What I discovered when the issue happens, is that there's an instance (just an instance only), that has an high number of threads and CPU usage on the W3WP.exe process and these values are above the mean than the other instances. Eg, instances are around
50/60 threads and 10/20% of CPU, the instance with the problem has 200 threads and 50/60% of CPU. If I kill the W3WP process on that instance the issue is resolved.
I monitored the HTTP requests, I tried the website extension "Diagnostics as service" but I can't discover anything that can help me to understand the problem. Of course, there are many requests that go in timeout but it is a consequences of a
unresponsive instance.
On the web hosting plan there are only two sites: the production site and its staging which is used for update of the production only and it's always sleeping. Plus, no webjobs are running on this site.
What can I do to gather useful information that can help me to understand the reason of this problem?
Thank you!"Does the instance with the high counts receive more traffic than the other instances? Is it possible that the load balancer not
working the way it should be?"
How can I get that information? I can't see metrics for a specific instance
"Does it always happen to the first instance?"
I will check it better, but in the order given by the Processes panel it's the second instance which has the issue. The scaling is at 2 instances for the most part of the time (it's the minimum).
Maybe one time it was the 3th instance but I'm not sure, I'll give it more attention.
" How long do these moment last?"
The time can be 10 to 30 minutes, but I fix it as soon as I see the problem. It's not the down-scaling to resolve it because in these situations the CPU as well is high so the scaling holds or increases the number of instances.
"- How often do these moments occurs?"
It occurs quite often, 2/4 times a week. -
K8NGM2-FID problems: no usb and high cpu usage - HELP!
hi folks,
i've setup K8NGM2-FID inside an htpc with a clean install of mce 2005 (onboard video). For the past couple of days I've noticed a few things:
1) if the pc goes into standby (S3) and then wakes up, sometimes task manager shows a cpu usage of 50% (on the graph) but looking at the list of tasks (for all users) nothing is runing that high - in fact system idle process shows 98% (while the graph is still showing about 50%) and the system is a bit sluggish; reboot fixes this but it's getting really annoying. I've installed the latest AMD x2 driver. Sometimes it goes to 98-99% after waking up but that's been rare.
2) i've been getting a few BSODs lately, actually all started yesterday - 3 of them in a span of about 2 hours after insalling Nero. I'm going to try to figure out what is causing it that (proabably Nero - I hope since that's easy to undo) but what i've noticed is that when the system reboots after the blue screen, none of the USB devices work (i.e. keyboard, mouse, etc.). windows has to load, then I need to go in the back and unplug/replug the usb devices which then 'wakes' them up; this can get really annoying in a typical cramped home theater setup. software restarts seem to be good - ok hardware restarts are the problem. hooking things up to a usb hub has the same effect - i.e. I need to re-plug the hub to get them to work - it just means less things to plug/unplug.
has anyone else noticed this? help save my sanity - this is driving me crazy. since this is an mce setup, it goes into sleep and wakes up several times a day so the high cpu issue when it comes up really gets in the way of using the pc. btw. during high cpu times, no mce related function (record/watch/the shell itself) is running.
here's my setup:
K8NGM2-FID - boots up with 3 short beeps - I think it's 1 beep pause then 2 beeps
2 gigs kingston 3 CAS (2 x 1 GIG kit) pc3200 - boot screen shows it running at 400mhz in dual channel config
X2 3800+ stock fan/heatsink with silver 5 (runs around 35-38 idle - inside a silverstone 'stereo rack' case)
ms usb keyboard/mouse/mce remote
coolmax 550W power
3 140GB WD drives (ata 133 - not sata)
onboard video - framebuffer set to 128megs
latest (as of 2 days ago) nvidia and msi drivers - msi bios is the stock 3.0 (more on that later)
the bios settings are all default as far as I can tell.
pvr-150 tuner card
promise ata 100 card
nec 3500dvd
all running on mce 2005 with rollup 2 and all the updates windows could find
i haven't updated the bios because i've read about other folks having blue screen problems and the suggestion has been to up the voltage for the ram (I guess the default setup from MSI is lower than it should be) but apparently that option is missing from the 3.1 and later bioses? and reading the text file, it wasn't very apparent what the bios 3.1 was fixing other than a few cosmetic bootup texts. I'm planning to up the voltage later today.
anyhow, any suggestions short of throwing the entire pc out the door are welcomed.
thanks!ok here's what I've found about the high cpu...
using process explorer, hardware interrups is taking all the cpu. i've tried to disable items one by one but nothing is working so far. what does work is if i choose scan for new hardware, cpu goes down to normal. standby and resume and cpu is up again. do the scan and it goes down again - without changing anything.
i've re-installed the graphic board driver, nvidia 430 drivers, sound driver. not sure what else to do. checked my drives and they are all properly master/slave set.
this is really getting crazy...anyone come across this?
i'm a bit hesitant to go to bios 3.1 since i've seen lots of posts about BSOD and i've just gotten rid of that.
thanks
thanks a bunch! -
High cpu usage and game lag problem
i have a hp 15 d103 tx
windows 8.1 64 bit
inel i5 4200m 2.5ghz
anti virus installed avast fee antivirus
im using nvidia 820m geforce 344.75 version driver
ram installed 8gb
im experiencing huge amount lag in games and software (autocad)
whenever i run a game (for eg batman origins) it run smooth till 2 or 3 minutes after it lag horrribly
for sake first im getting 45 frames per second then suddenly frame drop to 13 or even to 10
i have to press alt + tab to check task manger it show cpu usage 30%
after that when again i press alt tab to back to game it runs fine for 20 seconds and again lag
i dont what the problem high cpu uasge
system idle process sometime shows around 82%
with 8gb of ram still expericing lag
this problem is with all game that i have played and software like photoshop and auto cad
my cousin own hp 15 r007tx and having same gpu nvidia 820m game runs for on his laptop without a lag
is it window 8 problem or something else??wow finally got the solution by updating bios
just updated the bios from 2.7 to 2.8
no lag now
i guess different cpu load gpu switching on off was problem
but now everything is running good -

I have run a full repair on disk permissions but it hasn't resolved this issue. SMJobRemove seems to be an SDK function for removing a job from the Service Manager based on a simple search I did. However, I can't see what would be causing this particular error. Everything else was working fine (and still is, except this MRT problem that started today). -
2800s, AIM-VPN-SSL2, vrf aware IPSEC, high CPU low throughput
We have a couple of new 2821s deployed across a fibre link and they were originally running 12.4 (non T) versions using software encryption. We would get around 8Mb/s throughput. Upgrading to T to use the installed AIM cards we now see the AIM cards in use (show cry isakmp sa det shows then engine as aim vpn), but we still get the same throughput and high CPU. allowing CEF on the interface doubles throughput but with the same high CPU. The only process I can see going high is IP Input. Is this because of vrf aware ipsec - or any other suggestions?
Hi Nick,
I am having the same issue. We have a 2851 as a IPSEC VPN headend with an AIM VPN module but we are seeing high CPU usage(80%) with just 4-5mbps worth of traffic. I have an idea that I might have a NAT issue.
We are currently running, NAT, ZFW, and IPSEC site 2 site VPN on the router.
When I look at my ZONE firewall policy-map output it is showing all of my VPN traffic as process switched.
Inspect
Packet inspection statistics [process switch:fast switch]
tcp packets: [14809800:0]
udp packets: [145107:0]
icmp packets: [20937:12]
I have disabled the ZFW and still see high cpu although it is a little lower.
Packets are not fragmented, CEF and fast switching looks to be enabled. I am using a route-map for my nonats. That is the only thing I can think of now.
I have tried IOS 12.4(20)T3,4 and 12.4(15)T9. Same results.
Anyone have some ideas?
