High CPU process every night at 1am

Every night at approximately 1 am the CPU load is high for a while. How can I find out which proces is responsible for the high CPU load?

Fell asleep at keyboard so didn't see it this time. Below bit of the system.log from the time it all started.

ICloud Photo not syncing + High CPU process (Win 8.1 pro)

This is a new persistent issue with my iCloud and I can't figure out how to fix it permanently because I was able to fix it few days ago, but issues return back a day later! So here's the full story...
I just received a new (AWESOME!!) Surface Pro 3 i5 256 GB tablet with Windows 8.1 professional. I installed iCloud on it as well as iTunes and Quicktime (the basics isn't it?). When setting up my iCloud account first, everything sync up correctly but after a few days (3-4 days), I notice than my Surface tablet are becoming pretty hot and making some fan noise (common Surface issue) when I didn't use it really. So I checked for a high-CPU process and I noticed than "iCloud Photo Stream Downloader" are stuck at 30-35% CPU for an hours ago. Moreover at this point I realized than my photos are not syncing for a few days. I fix the high-CPU process by rebooting, but my photo are still not syncing at all and after a few minutes after reboot, the "downloader" process stuck back to 30-35% and still not syncing!
So I first try some of the workaround found on the internet like sign out iCloud app, then kill all iCloud related process and delete folder %appdata%/Apple/Mediastream and reboot and sign in... same thing... after a few minutes, high-CPU usage + not syncing! I try to "repair" iCloud installation... same thing (high CPU + not syncing)... I uninstalled iCloud + reinstalled... same thing!
I finally fix the situation by uninstalling ALL Apple related software (iTunes, iCloud, Quicktime, Apple Soft Upd, Apple Mobile Sup, Apple App Sup, Bonjour, etc) and thereafter deleting all "Apple_xxxx" folders in %appdata% and also remove all registry keys from the Windows Registry related to Apple. Reboot then reinstall iTunes first and then run "Apple Soft Upd" to install automatically iCloud + Quicktime... then reboot, sign in and then the photo finally sync this time and no high-CPU process!
But a days later... High CPU + Fan noise on the tablet... so checked and the god **** "iCloud Photo Downloader" are again stuck at 30-35% and no more photo sync (I saw the old photos, but not the last day's photo are not sync).
Anybody experience this situation and know how to fix it PERMANENTLY? I checked at my Apple iCloud LOGS and the only thing I saw that can be suspicious is the last line of the log who's :
[2472 @ Tue Nov 11 19:45:09 2014] [YSLog ApplePhotoStreamsDownloader.exe] defaults key ShouldLog in domain ApplePhotoStreamsDownloader.exe is (null)
Please help!!

In fact I discovered later I have this issue on all my Windows computers... both Windows 7 and Windows 8.1, both MACs (BootCamp) or true PC computers. Except only the Surface Pro 3 tablet seem to have the HIGH-CPU process issue, but all my other Windows PCs stopped syncing too after a few weeks or so.
I just build a BRAND NEW HP Pro Desktop computer running Windows 8.1 Professional and a few days later iCloud Photo stopped syncing too... this is the straw that broke the camel's back! This PC is brand new and no other software are installed except iCloud, iTunes, QuickTime and Microsoft Office 2013 (Office 365). PC is brand new (1 week old) and iCloud Photos sync is already broken!
I also have a few Windows 7 PCs at home (HTPCs on TVs) where iCloud Control Panel is installed and after looking at them, they stopped syncing too for a while (many months ago) but I didn't noticed it yet because I don't check photos often on them.
For now I just give up and disabled the iCloud Photo Sync completely on all my Windows PCs. It only sync between my two iPads, my two iPhones and my two Macs computer (MBPr + iMac 27") and that's it... that's sad, but I'm tired loosing my time with that crappy software!
PLEASE APPLE!! MAKE ICLOUD FOR WINDOWS BETTER!!

Pageserver.exe showing high CPU processing on server

We have been running Crystal Enterprise 10 for awhile on the same server. Starting Thursday evening the pageserver.exe process showing high CPU utilitzation on the server. We have restarted all the Crystal services through the Central Configuration Manager but the problem still came back. The high CPU utilitization occurs during the day and at night when no one would be running any reports. Does any know what else we could look for?
Also does a separate pageserver.exe start for each user that runs a Crystal report, we show about 6-8 pageserver.exe processes at any given time. Is that normal? When do these pageserver.exe processes go away. I logged out of Infoview but a pageserver.exe process did not go away.
Thanks

High CPU/Process hang on VDI environment

I have a environment that is currently using Adobe Reader XI running on roughly 125 virtual desktops.
In some of those instances, when adobe reader was launched and closed after, the process hangs up in the background and takes on high CPU. The only means to recover is to open task manager and kill the offending .exe
Thoughts?

Can you try to disable Protected Mode in Adobe Reader [Edit | Preferences | Security (Enhanced)].

I cannot find anything about the process K5L3Unicast Adj Tabl on yhe internet.

Hi
The platform-process “K5L3Unicast Adj Tabl”, that causes the high CPU usage is a platform-process that is active when a new MAC address has been learned and the adjacency table is rewritten. This takes place when in the switch receives an unknown source MAC address, it’s forwarded to the CPU for MAC address learning.
It could be possible to have a device connected to a switch port sending lots of MAC address randomly and massively forcing the switch to spend all CPU capacity just to process the new MAC addresses.
So next step is check the interface statistics looking for the highest traffic rate. Use this link below in order to troubleshoot this issue and find the top offender interface.

Lightroom Mobile Sync - Extremely High CPU Usage/Sync Process Causes LR To Lag

Since my other thread doesn't seem to be getting any responses, I'm pasting what I've found here. Please keep in mind I am not a beginner with Lightroom and consider myself very familiar with Lightroom's features excluding the new mobile sync.
1st message:
I'm on Lr 5.5 and using the 30 day trial of Adobe CC to try syncing one collection of slight more than 1000 images. Despite already having generated the Smart Previews, I can see my CPU crunching through image after image (the rolling hills pattern in the task manager) while doing the sync. I was assuming, since I already created the Smart Previews, that the sync of this collection would begin immediately and be done by simply uploading all of the existing Smart Previews. The Smart Previews folder of the catalog is 871MB and has stayed the same despite the CPU obviously doing *something*. As it is now, the sync progress is incredibly slow, almost at a pace like it's actually exporting full-res JPGs from the RAW images (as a comparison only, I know this should not be what it's actually doing).
Another side effect of this is that I'm basically unable to use my computer for other tasks due to the high CPU utilization.
Win 7 x64 / Lightroom 5.5
Intel i5 2500k OC'd 4.5GHz
16GB RAM
SSD for OS, separate SSD for working catalog and files
2nd message:
As a follow up, now Lightroom thinks all 1026 photos are synced (as shown in "All Sync Photographs" portion of the Catalog though all images after the 832nd image show the sync icon per image stuck at "Building Previews for Lightroom Mobile" and the status at the top left corner has been stuck at "Syncing 194 photos" for over 12 hours. Is there no option to force another sync via Lightroom Desktop and also force the iOS app to manually refresh (perhaps by pulling down on the collections view, like refreshing via the Mail app)?
3rd message:
One more update, I went into Preferences and deleted all mobile data, which automatically signed me out of Adobe CC and then I signed back in. Please keep in mind the Smart Previews were long generated before even starting the trial, and I also manually generated them again (it ran through quickly since it found they were already generated) many times. Now that I'm re-syncing my collection of 1026 images, I can clearly see Lightroom using the CPU to regenerate the Smart Previews which already exist. I have no idea why it's doing this except that it's making the process of uploading the Smart Previews extremely slow. I hope this time around it will at least sync all 1026 images to the cloud.
4th message:
All 1026 images synced just fine and I could run through my culling workflow on the iPad/iPhone perfectly. Now I'm on a new catalog (my current workflow unfortunately uses one catalog per event) and I see the same problem: Smart Previews already generated but when syncing, Lightroom seems to re-generate them again anyway (or take up a lot of CPU simply to upload the existing Smart Previews). Can anyone else chime in on what their CPU utilization is like during the sync process when Smart Previews are already created?
New information:
Now I'm editing a catalog of images that is synced to Lightroom Mobile and notice that my workflow has gotten even slower between photos (relative to what it was before, this is not a discussion about how fast/slow LR should perform). Obviously Lightroom is syncing the edited settings to the cloud, but I can see my CPU running intensively (all 4 cores) on every image I edit and the CPU utilization graph looks different than before I started using LR mobile sync. It still feels like every change isn't simply syncing an SQLite database change but re-generating a Smart Preview to go with it (I'm not saying this is definitely what's happening, but something is intensively using the CPU that wasn't prior to using LR Mobile).
For example: I only update the tint +5 on an image. I see the CPU spike up to around 30-40%, then falls back down, then back up to 100%, then back down to another smaller spike while Lightroom says "Syncing 1 photo". I've attached a screenshot of my CPU graph when doing this edit on just one image. During this entire time, if I try to move onto edit another image, the program is noticeably slower to respond than it was prior to using LR mobile, due to the fact that there appear to be much more CPU intensive tasks running to sync the previous edit. This is proven by un-syncing the collection and immediately the lag goes away.
I'd be happy to test/try anything you have in mind, because it's my understanding that re-syncing photos that are edited that are already in the cloud should be simply updating the database file rather than require regenerating any Smart Previews or other image data. If indeed that's what it should be doing, then some other portion of LR is causing massive CPU usage. If this continues, I will probably not choose to proceed with a subscription despite the fact that i think LR mobile adds a lot of value and boosts my workflow significantly if it wasn't causing the program to lag so badly in the process.
I know this message was incredibly long and probably tedious to read through so thanks in advance to anyone who gets through it
-Jeff

Thanks for reporting. Just passed along your info to some of our devs. One of the things that needs to be created (beside smart previews) during an initial sync are thumbnails + previews for the LrM app - Guido
Hi Guido,
Thanks for pointing this out. I realized the same thing when I tried syncing a collection for offline mode and found out the required space sounded more like Previews + Smart Previews rather than just the Smart Previews.
greule wrote:
Hi Jeff, are your images particularly large or do you make a lot of changes which you save to the original file as part of your workflow?
The CPU usage is almost certainly from us uploading JPEG previews not the Smart Previews - particularly during develop edits as these force new JPEG previews to be sent from Lightroom desktop, but would not force new Smart Previews (unless the develop edits are modifying the original file making us think the Smart Preview is out of date) to be sent.
Guido
My images are full-resolution ~22mp Canon 5D Mark III RAW files so they're fairly large. Even if I only make one basic change such as exposure changes, I saw the issue. By "save to the original file" I'm assuming metadata changes such as timestamps, otherwise edits to the images aren't actually written to the original file. I'm only doing develop module edits so I shouldn't be touching the original file at all at this point in my workflow.
I think it makes sense now that you mention that new JPEG previews need to be generated and sent to the cloud due to updated develop edits. My concern is that this seems to be done in real-time as opposed to how Lightroom Desktop works (which is to render a new Standard Preview or 1:1 Preview on demand, which means only one is being rendered at any given time while viewing it in Loupe View or possibly 2 in Compare View). If I edit, for example, 10 images quickly in a row, once the sync kicks in a few seconds later, editing the 11th image is severely hindered due to the previous 10 images' JPEG previews being rendered and sync'd to the cloud (I'm assuming the upload portion doesn't take much CPU, but the JPEG render will utilize CPU resources to the fullest if it can). Rendering Standard/1:1 Previews locally and being able to walk away while the process finishes works because it is at the start of my workflow, but having to deal with on-the-fly preview rendering while I'm editing greatly impacts my ability to edit. Perhaps there can be a way to limit max CPU utilization for background sync tasks?
It may help to know that I'm running a dual-monitor setup, with Lightroom on a 27" 2560x1440 display maximized to fit the display (2nd display not running LR's 2nd monitor). Since I'm using a retina iPad, the optimal Standard Previews resolution should be the same at 2880 pixels.
Thanks again for the help!

How can I find which is doing a "show run" ? Which debug can I do ?
Thanks

We solved our problem it was caused because we were routing in and out the same L3 interface.
Fixed this issue and our CPU dropped dramatically.

High CPU - SNMP ENGINE process

Based on the stace trace, how do I determine what object is being polled??? (what is causing the high cpu for SNMP ENGINE)
From the “show stack 295” output (SNMP ENGINE)
router>show stack 295
Process 295: SNMP ENGINE
Stack segment 0x68226DC0 - 0x68229CA0

Thanks

Yeah, I backup srkala. Currently we dont have any external tool to decode the stacks.
These stacks needs to be decoded on the source code server for every perticular IOS and hence can't be made external.
For any issue you need to collect and post either to CSC, we can check that, or you can open the TAC case to get it reviewed.
Also, the decode information doesnt reveals much, it further needs processing to which will be out of scope for anyone without some intenal tools help.

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

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.
Regards

Mid-2009 macbook pro high cpu temp ( 100C) after every cold boot

Hi everyone,
Every time I cold-boot my MBP, the CPU temperature sky rockets to 100C within 3 minutes at idle with the fans barely kicking in until that point. The activity monitor shows 97% idle with no major processes running and this issue is reproducible every time I turn on the computer. However, if I immediately reboot the computer (warm boot), the computer runs normally (~70C CPU temp, fans @ 2000 rpm). If I do a SMC reset, the computer boots normally for the next immediate single cold boot but symptoms return thereafter. The only way to prevent the high CPU temperatures is to do a SMC reset before ever cold boot.
I'm wondering if someone else has had these symptoms with their laptop and how they fixed it. The system is still under apple care and the symptoms are reproducible but I'd rather not bring it in as this is my daily-use machine.

Are there any specific tests, or logs prior to isolate this issue?

Hi,
A few points:
> Use one of the recommended OVA templates
> Check if the spike is random or occurs at a specific time. If it occurs at a specific time it could be coinciding with something like DRS backup, CDR load, busy hours etc.
> Minimum set of logs needed for one such high CPU spike instance are:
Detailed ccm traces from all nodes
RisDC Perfmon logs
Proglogs
Also, capture the output of the following:
utils diagnose test
utils core active list
show process load

Java process - high CPU usage

Hi,
I'm describing a high CPU scenario which gets triggered randomly ( I'm not able to replicate it on my lab setup).
There are around 120 threads which are running in my java process. The jvm is running on a high traffic (through put) site, where there are a lot of async events coming to the java process.( around 220 events per 60 seconds ). The java process works fine in this scenario, the normal CPU consumption hovers around 1.5 % to 2.0 %.
But, at times, I've seen CPU to be as high as 43 %, and it stays at that value for hours altogther. In those situations, I usually do a failover to standby java process. I tried debugging the issue to see which java thread could be causing the issue, but, I could not come to a conclusion or replicate the situation in lab environment.
Here are the details of the execution environment
java -version
java version "1.4.2_11"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_11-b06)
Java HotSpot(TM) Client VM (build 1.4.2_11-b06, mixed mode)

Some more points about the last prstat -Lm output.
java/2 is "VM Thread" ( responsible for GC). "VM Thread" is having a NORMAL priority ( 5 )
java/26 is a "Worker" thread, with priority MINIMUM ( 1 ).
Could you suggest what could be issue, and what other information I could collect to find out the issue. Its difficult to profile the process because the problem scenario is difficult to ascertain and the process is running on a production setup.
Any help is appreciated.
Thanks
Sanjay

Hi,
Thanks for your response. Both, the production setup and lab setup have have 2 physical CPUs.
Actually, there are two java threads ( machine is solaris 10) one is "VM Thread" and other is my applications worker thread. (there are 10 of them with priority 1). If you look at the top two lwps in the prstat -Lm , both are showing high value of ICX.
I'm still not able to drill down to my code level. (Worker thread is waiting on a queue to de-queue server request). Could you give some hint to move foward?

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
