What is "Node 0 Normal"? Where could I read more about this?
Am I right that it could be a problem because of large Pagetables?
Thank you for help!

According to some vague info I can find you need to switch from PVM to PVHVM. Perhaps the following links are useful: Converting Guest to PVM from HVM
Which kernel to use for paravirtualized guest OS - XEN or UEK?
The Oracle UEK kernel will automatically detect and switch. You can download appropriate templates from the Oracle edelivery cloud. There is actually a separate forum that discusses OVM issues, which should be more suitable for this topic.

OOM Killer is killing the Java processes without using the swap?
Hi All,
We are using RHEL 5 64 bit on blade server CISCO UCS B230-M2.
Below is the memory details on the server. I could see from the sar -r command it did not used the swap memory at all but it calls the OOM killer everyday.
su@ /root-> free -g
total used free shared buffers cached
Mem: 125 119 5 0 2 81
-/+ buffers/cache: 35 89
Swap: 251 0 251
The issue is occuring every day and doesnt allow any user to connect to the server in that perticular time, After some time we could see the below messages in /var/log/messages and once the java processes are getting killed it allow the new telnet connections.
Any help on this is much appreciated.

Thanks,
Sachin.It looks like you experience low memory exhaustion. The kernel uses low memory to track allocations of all memory and the more memory you have, the more low memory will have to be allocated. When low memory is exhausted, it doesn't matter how much high memory is available, the oom-killer will begin killing processes to keep the server alive. There are a number of bug reports and patches available regarding this problem affecting Enterprise Linux kernels 4.4 - 4.8. Other solutions are to move to a 64-bit kernel or use 32-bit hugemem. Are you running NFS?
Perhaps you might want to try the following:
# cat /proc/sys/vm/lower_zone_protection
You can try to increase the value and see what happens:
# echo "250" > /proc/sys/vm/lower_zone_protection
To set this option on boot, add the following to /etc/sysctl.conf:
vm.lower_zone_protection = 250
As a last resort effort, you can disable the oom-killer. This option can cause the server to hang, so use it at your own risk.
Check status of oom-killer:
# cat /proc/sys/vm/oom-kill
Turn oom-killer off/on:
# echo "0" > /proc/sys/vm/oom-kill
# echo "1" > /proc/sys/vm/oom-kill -
Hi,
I'm not sure what's wrong maybe low memory? but oom-killer is killing processes like "nscd" making the host non-functional. It seems that swap space is not being used at all for some reason.
Can someone look at the following and tell what's wrong?

Lion 10.7.2 On both mac book pro and iMac, both with Lion 10.7.2, obtain repeated iCal event notifications from calendar or address book. Cannot turn these off. They repeat several times per session and every time computer is used. How to diagnose this?
First, uninstall "SuperTV" (whatever that is) according to the developer's instructions. It isn't working and it's filling the log with noise.
If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time when you had the problem. Post the messages logged before the boot, while the system was unresponsive or was failing to shut down. Please include the BOOT_TIME message at the end of the log extract.
Post the log text, please, not a screenshot. If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message. When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
PLEASE DO NOT INDISCRIMINATELY DUMP THOUSANDS OF LINES FROM THE LOG INTO A MESSAGE. If you do that, I will not respond.
Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post shutdownStall, spin, or hang logs — they're very long and not helpful. -
How to diagnose dead battery vs. something more serious?
I'm in the 11th month of ownership of an MBA, purchased brand new last year. 128MB model.
My battery, I believe, is dead but I'm not sure how to diagnose the matter.
Here's what's lead me to this conclusion:
MBA charger light stays off when plugged in (not dim, but off). I've had the dim light issue as well, earlier this year, and Apple replaced the charger. This time, however, the light stays completely off.
Battery icon in top right corner tells me that no charger is plugged in. The icon is in battery mode.
Battery charge keeps decreasing steadily in % value despite charger being plugged in, indicating that battery is continually discharging.
My wife has an MBP, and I've used her 85W charger on my MBA with the same result... i.e charger light stays off. I know that the MBP charger is in good health as it charges the MBP with no issues (orange light).
I've used my MBA charger on her MBP, and it charges the MBP just fine!!! (orange light)
I've done an SMC and NVRAM reset on the MBA, which hasn't affected the situation.
Since I'm on 15% charge on the MBA, I've shut it down and have booked an appointment with Apple to have it looked at.
In the mean-time, I'm hoping to get some clues from fellow MacBook users on this forum.
I've read somewhere that if it is indeed the battery that's faulty, then once the charger is unplugged, the MBA should turn off immediately. This isn't the case for me... I'm able to run off battery (whatever tiny amount of charge I have left) with the charger unplugged.
Hence, I've ruled out the charger being faulty. I'm not so sure that the battery is faulty. I'm thinking the issue might lie elsewhere... maybe the magsafe connector on the MBA?
I should also mention that when I opened the lid on the MBA earlier this evening, before noticing this charging issue, the screen flickered brightly once. The screen looked and operated normally after the flicker. Not sure if there's a connection. I'm beginning to think there is.
I should also add that, even though the MBA has been a pleasure to use, the past 11 months haven't been trouble-free... which adds to the suspicion that the issue might indeed be somewhere deeper.
A brief history of "issues":
About a month or so into ownership... my fan, one day, decided to suddenly spin up to full RPMs and stayed at that speed for an eternity. I'm used to the fan speed steadily going up in direct relation to the CPU temp. However, the CPU temp this time was 35C the entire time (according to iStat Menus)... i.e. the MBA was "stone cold". It made no sense for the fan to be on full-blast. In addition, I had nothing running. No intensive software. Not even Safari. Just "Finder". Turning the MBA off naturally caused the fan to stop. However, the moment I powered it back on again, the fan came back on at full speed again.
An SMC reset fixed the issue, and I was good to go. This issue occurred again a few months later, but I solved it right away with the SMC reset.
After another month or so I noticed, while listening to music via headphones that were plugged into the MBA, that I could hear an electric "hum" in the headphones. Then all of a sudden the hum went away. I discovered that the hum was present only when I physically touched the metal case of the MBA and went away as soon as I removed my hand. I mentioned this to a Genius bar... err... genius and he seemed perplexed. He wasn't able to offer an answer.
I've also noticed that when the MBA is charging, and I run my finger-tips over the MBA's metal surface that I feel static. When the charger is unplugged, I no longer feel the static. Again the genius didn't have an answer. He probably thought I was weird.
I'm thinking my MBA might have "grounding" issues, but am no expert in this field. With the latest charging issues, however, I'm leaning towards this theory again.
Thoughts are welcome.
Regards
MrAirNo clues, it is very apparent you have a hardware problem and it is not the battery. If it was the battery the computer would not be running as you say the charger is not charging the battery.
There is a charging curcuit that has more then likely failed. You have done the correct thing, take it in and get it fixed before your warranty runs out. -
How to diagnose flickering exported JS animations from Flash CC?
Quick stats on my system:
Macbook Pro Retina 2012 running OSX 10.9.3
Flash CC 13.1.0.226
I'm not experiencing an error so much as a lack of understanding about how to diagnose Flash CC JS export issues. Here's the backstory:
In 2012, my company started working with an contract sprite artist. I was using the CS5.5 Creative Suite, and we were exporting normal png sequences from Flash for use in the game. After about 8 months, my cofounders and I realized that we could both reduce the load time for the game and also allow our artwork to be dynamically scalable by switching to JS exports of our art rather than the raster sprite sheets. Here's the blog post we wrote about it: http://blog.codecombat.com/hacking-our-way-to-vector-artwork-in-html5
At the time, I didn't have Flash CC, and was reliant upon the CreateJS plugin to export the required JS files: CreateJS Developer Center | Adobe Developer Connection After another month or so, our contractor upgraded their version of Flash and we started having compatibility issues reading FLA files, so I upgraded as well. After doing some reading, I concluded that the CreateJS plugin was now incorporated into Flash CC as the HTML5 doc type, which was confirmed when I checked out the publish settings and resulting files.
This is all a rather long winded way of saying that we have legacy artwork created with an older version of Flash but are now importing all of our artwork from JS files.
Fast forward to today and we have two big issues:
1) We can't figure out how to reduce the filesize of JS exports. As discussed in our blog post, vector artwork has upsides and downsides. One of the downsides we've found is that complex art that uses a lot of shapes ends up being substantially larger (in terms of filesize) than the appearance might otherwise suggest. Raster exports skirt this because a pixel is a pixel, but vector exports scale with the complexity of the source FLA. I'm not a Flash expert, and when we get files that are particularly complex, Flash either runs out of memory exporting them to JS files or we get files that are far too large to reasonably use. To be clear, the "out of memory" error isn't a problem because even if Flash finished the export, the resulting files would be too large for us to use (plus, I've done some digging and found a tutorial for correcting the out of memory error). Our artist is not familiar with the intricacies of the JS Flash exporter, so when we get a file that's too big or breaks the export, neither of us can really figure out a way to correct the problem. We have three questions in particular:
a) Where can you view shape data that Flash is going to write to the JS files?
b) Is there any way to edit said shape data inside the Flash CC interface?
c) Is there any way to optimize shape data in Flash? For instance, in Photoshop, you can flatten images and export a psd with 500 layers as a single JPEG, is there any way to do something similar to shape data in Flash?
2) Exports frequently break in weird ways. Many of the sprites that we created a year ago haven't needed to be re-imported into our game engine for some time. But every once in a while, I need to go back and fix, improve, or tweak an existing sprite, and then I run smack into the issue of reconciling files that were created without thought to JS exports with our current system. Just last week I was running into this issue in a big way and I made a screencast for our artist (since we work remotely) that I hoped might give him a better idea of the problem: Flash Errors - Treasure Chest, Flippable Tile - YouTube
The two files mentioned in that screencast are both old (treasure chest) and new (flippable land tile). We have a few questions:
a) Why are the treasure chest frames "flickering" in the html5 preview? The problem doesn't appear inside Flash and is inconsistent between files. There are two FLA files: one in which the treasure chest is empty, and one in which it's full. The empty animation doesn't throw any errors, either when converting to the HTML5 doc type or on export, but the resulting animation flickers. The full treasure, on the other hand gives me 21 lines of these errors when I do the conversion (not when I export): "Blend Modes(Layer) is not supported in HTML5 Canvas document, and has been converted to Normal in an instance of Movieclip <Path>." The result in both cases is the same: the animations flicker, and neither our artist nor us can figure out why, or for that matter, even begin to troubleshoot it. This SO issue seems to describe the problem, but was never resolved, and I can't find anything else that seems to address it: CreateJS Publish of Flash Project Flickers - Stack Overflow
I've uploaded the files involved to a public dropbox folder which I think you'll be able to access (Dropbox seems to be having some problems at the moment): Dropbox - flash_debugging
Since my questions are fairly involved, and my goal is to gain a better understanding of the UI, not simply resolve an error, I'd be happy to pay for someone's expertise/time in getting me up to speed. You can get in touch with me at george [at] codecombat.comHi George,
I have taken a look at the files full_treasure_chest.fla and flippable_land.fla that you have shared via drop box and found that they both uses blank keyframe(s) followed by Keyframe(s). This was an issue and has been addressed in the latest release Flash CC 2014 (released on 18 June, 2014). Can you please install the latest build 14.0.0.110 and try this out?
Thanks!

How to diagnose software / driver / video card issue?
My computer has been freezing up on a regular basis for the past few weeks . . .
I initially assumed it to be a bad stick of RAM, but I was able to reproduce the lockup with each stick individually.
I tried downgrading the kernel (but not Xorg or nvidia drivers), and that didn't fix anything.
At this point I don't really know enough (especially related to Arch specifically) as to how (which) log files to check for a reported error and issue.
The main issue of locking up occurs when I'm watching something on VLC at full screen. It's exacerbated with browsing or doing other stuff at the same time.
After a lockup I don't know if I should be checking journalctl / dmesg / Xorg.log / htop / etc . . .
Any advice / direction of stuff I can be checking after a crash would be MUCH appreciated. It really sucks not being able to use my PC like I used to.
If it help any my board/RAM are ~6yrs old, but the gfx card is new as of this year (I am using the regular nvidia drivers and multilib): EVGA 02G-P4-2645-KR GeForce GT 640

Hi, I also have stability issues so I am also interested in tips how to diagnose an unstable system. In my case, in journalctl the problems right before freezing can be seen, e.g.

I tried various video drivers; nvidia 304, 325, 331 and nouveau, but in any case the system freezes after playing video for half an hour or so. The problem is more rare on a 32 bit installation than 64 bit, so perhaps you could move from 64 to 32 bit?
sorry for your troubles! i am not sure what the exact issue is, but i am on nvidia w/ video troubles as well . . . i have been running atop 24/7 and notice high r/w use of my disk at times when playback starts to stutter . . .
i haven't had a full-on lockup in days, but have still had one in recent time. i am not really sure how to trouble shoot this further. -
Re: javax.faces.convert.Converter error, how to diagnose?
I’m rendering a region on a page. The region is a table which is entirely build in java. The .jsff for the region looks kind of like this:
<af:treeTable value="#{backingBeanScope.myBean.treeModel}" var="row" etc…. >
<af:forEach items="#{backingBeanScope.myBean.columns}" var="column">
<af:column binding="#{column.adfColumn}" />
</af:forEach>
</af:treeTable>
When a row selection happens, there is context menu build, where one of the menuitems pops a dialog. After the dialog is dismissed a return handler/listener is called:
public void propertyToolReturnHandler(ReturnEvent event)
AdfUtil.showMessageDialog(AdfUtil.MESSAGE_TYPE.INFORMATION, “some msg”, “some msg”, true);
Notice the last param to showMessageDialog, which is “true”, as I want to show the message as inline. However, having it set to “true” causes the following exception. If I set it to “false”, then it does work and a popup message appears with the “some msg” text.
I’m truly stuck trying to figure out what Converter is missing and where. Any ideas will be most welcomed!
The error I get:

Edited by: user12869467 on Apr 12, 2013 1:57 PMI did more trial/error with this problem. It is not related to AdfUtil.showMessageDialog().
My java-built table, shows a popup. After the popup is dismissed, I will get this exception, not right away though. The view has tabs, if after dismissing the dialog, I navigate to some other tab, and then back to the one which has the table, that is when the error shows up.
ANY help on how to diagnose this problem will be very much appreciated!

How to diagnose HTTP 500 Internal Server Error
Hi all,
I have installed SSM 7.5 SP05 Hot Fix 1 on a Windows 2003 Server (64 bits), but in the End User Interface, the Home and Strategy tabs always shows an HTTP 500 Internal Server Error, how can diagnose this kind of error in order to solve this problem? Other tabs, for example the Initiatives tab works fine, the problem is only with the Home and Strategy tabs.
Thanks in advance.
Best Regards,
DouglasHi Ricardo,
After configuring the model connections all is working fine, thank you!
I have the idea that in previous versions that is not needed and just affect the Scorecard tab, now I know that if affects other tabs too, however, instead of HTTP 500 error would be more helpful another message that suggest the configuration as a requirement.
Again thanks for your help.
Best Regards,
Douglas -

Oom-killer close firefox and then X restarted
Hi everybody!
I'm using Arch for couple of years and never experience this kind of problem.
A week or two ago my XFCE session start to close at a random time (but everytime it's when screen locked and XScreensaver runing).
When it happen, system redirects me to SLIM. This situation continue to happen every day (1 or 2 times in a day).
And every time I saw in logs same picture: oom-killer shutdown firefox and then X server restarted.
I don't understand where to search for solution and what process make a problem.
Maybe it's normal situation?

Any advice would be appreciated.Today I've got same system behavior, but no out of memory now, rather X got bus error and restart.

Try a system maintenance utility like Yasu:

Free for use, though the developer accepts donations.
Most likely you need to repair permissions and Yasu will do that for you and some other general housekeeping. -

I have a server which I am getting several OOM kills during periods of high system activity. At first, I thought that the amt of
system memory was just too low. I increased RAM, swap to 8GB each which did not help, I installed the lastest kernel from 2.6.9-89.0.11.0 to 2.6.9-89.0.16.0. We are running RHEL 4.8.
The issue started around 10/18/2009, on 10/10 we migrated to Oracle support for the OS, and ran updates. Any ideas as to where to look next would be appreciated. I can provide more info if needed.

If your system still runs out of lowmem after changing this kernel tuning parameter, try booting the hugemem kernel. If even that is not enough, you need to look into moving to a 64-bit OS.

How to handle OOME in OSB/ALSB
In WebLogic the advice on OutOfMemoryError is to restart the server via the panic action in overload configuration.
However, in OSB an OOME is always caught by an OSB errorhandler, so I think that leaves you with the following options
1. in all your OSB errorhandlers call System.exit(), not nice since errorhandlers cannot be reused
2. configure JRockit to exit on OOME
3. monitor WebLogic/OSB log for OOME and take some action on that
What do you think?1. in all your OSB errorhandlers call System.exit(), not nice since errorhandlers cannot be reused
Not Recommended, OOM are runtime errors and you cannot predict the when/where they can happen. Why would you want to put system.exit in every error handler. this would be over-kill. Its like putting try-catch block for every piece of java code that is written.
2. configure JRockit to exit on OOME
May not be good idea either. Only some sub-system might be effected by OOM, other systems might not be...
3. monitor WebLogic/OSB log for OOME and take some action on that
This would be the best way if I have to choose from your given 3 options
You should not how ever forget that with step 3, we should also spend some (painful!) time to identify the root-cause of the OOM and eliminate either by changing program/logic or upgrading the hardware...That is the only long-term solution.
Thanks
