hi,
my problem is . i working on production in transaction SE11 and table VBFA . when i click on number of entries the system hangs up .
plz solve my problem .......................
it very urgent

Hi Pankaj,
May be the system is not able to process the request. You better check with the hardware guys for possible hardware tuning or upgrades.

IMac G5 system hang - 2 bad 1GB memory modules?

I am experiencing intermittent system hangs, requiring power off / on to recover. Applications run fine for hours, then everything freezes; a few seconds later the fans spool up full bore. There seems to be no logic to the failure. It happens on many different applications, including Disk Utility. No new software has been added recently (other than Apple software updates). This has been occuring for several weeks.
I repair permissions & run disk verify. When disk utility runs completely without hanging (on verify), everything is ok.
Applecare had me trash the ~/Library/Caches & system caches. No joy. They recommended archive & install beginning with Panther. Reinstall went ok until downloading updates for 10.4.8, then hang (might this suggest a hardware prob?).
Rebooted in target firewire mode the cloned drive, then zero'ed the G5 HDD and restored from clone (SuperDuper!). Everything appeared ok for several days, then the same system hang reappeared. I should mention that in the course of sudying this one, I discovered Virex 7.5 was sucking the processing life from the G5; used the uninstaller to get rid of it & the iMac is quiet again!
I have run the Applecare version of Techtools and the Hardware Test Disk, everything passes.
I could do a clean install of Tiger, then use migration assistant to move data from the clone...if I felt it had a chance to solve it. On the other hand, maybe its a flaky hardware gremlin and I'm wasting my time doing reinstalls, and I should hustle it over to the local Apple store.
Update - took iMac for service at Apple store where it failed under stress test with my 2 GB of memory but ran for an extended period with Apple memory. In an attempt to isolate which of the two 1 GB modules was bad, removed one module. Identical failure after 24 hrs. Howver, swapping out that failing module with the second module, identical hand. That suggests either both 1 GB modules are bad (unikely), or some other hardware issue is the problem.
Problem seems to occur most often when starting playing iTunes, or running Disk Utility (repair permissions).
I suppose the next step is to buy 1 GB of memory from Apple and make it fail again. Any suggestions?

Thank you for your posts, I appreciate it.
Skip - I tried a spare keyboard & mouse. Still failed.
MGW - all software is up to date.
DaddyPaycheck - I downloaded memtestosx. It fails testing each 1GB memory module separately (in different sockets). I'm running in multiuser mode and when it fails the entire iMac freezes up (just like it always does), requiring power off / power on. Is this normal behavior when the memtestosx test fails?
I will plan to test in single user mode as the supplied doc states that if the onboard cache is failing it would pass singleuser (cache apparently disabled in singleuser mode) but fail multiuser. Maybe the onboard cache is bad?
Thanks.

System hangs when copying large quantity of files from external HD

A little background:
I was having some problems with the original OS (10.4.1), including periodic freezes. I bought the Mac Box Set '09 and installed Snow Leopard (10.6.5), but ran into some problems and in the process had to reformat my internal hard drive. I backed up all of my photos (~16GB), Documents (~1.5GB) and Music (~50GB) on a WD external hard drive (My Passport 750GB).
*The problem*: After the 10.6.5 install, the computer works great (no random freezing when I click around in Finder), but I am having trouble copying files back to the internal HD from the external. I can copy up to about 1GB at a time without any problems, but any time I try to copy more than that, the system hangs (first the spinning disk cursor, then it totally freezes) and I have to do a hard reset. I have tried copying a number of different folders (pictures and music), and the same holds true: small folders with a few files copy without a hitch, but any time I try to copy a lot of files at once: freeze city. This problem occurs whether I am using Finder to copy the files or iPhoto/iTunes to import them.
I have verified both disks using the Disk Utility AND restructured/verified them using DiskWarrior. I also had no problem copying all of my files from My Passport to a second external HD using this MacBook, so I assume the Passport is fine. Is this a physical problem with my internal HD? If so, why can't DiskWarrior or DiskUtility catch it? I just noticed that there is an internal HD recall for this model of macbook, although I have never gotten the question mark on startup that would qualify me for a replacement HD from Apple. Maybe it's a problem with Snow Leopard... I would love to know if anyone has had this problem before or has some advice.
Thanks,
Sam

External USB/FW drives 'falling off' or drives spinning down (going to sleep) and I would assume since you have been running 10.4 that the Passport might be older model, perhaps not the latest firmware, maybe not compatible with Macs and with Snow Leopard.
Obviously you want FW800 but for some, USB worked where FW fails.
Hard Reset: do you have another hard drive to boot from to run Disk Warrior? is that updated to 4.2 or later? you never want to run DW from CD. Else, boot from OS X 10.6.5; or Single User and run FSCK. HFS+ doesn't take kindly to hard restarts even though a Safe Boot helps a little, that isn't as good as FSCK or one of the other options.
Disk Warrior Rebuild is more thorough, but if you hold OPTION while clicking on REBUILD it brings up more choices. And you want to scan the full hard drive.
Going back to Aug/Sept 2009, there were a lot of threads about external hard drive issues. Wish I could point to a good one.

Cannot install OS (system hangs) on K7N2GM-L

I've just put together a (mostly) new system. The system posts OK, but when I try to install either Slackware or Win2k, the system hangs. Slackware consistently hangs after recognizing the cd drive, with a message about a kernel bug, while Win2k hangs while loading hardware files, with a message about a registry error (As in a hardware registry, not the windows registry). At one point, I was able to get slackware further in the install process, and even partitioned the hd, but I kept getting segfaults and then it would crash.
[Update]: Slackware actually hangs in one of two places. Sometimes it hangs right after initializing the Ramdisk, at which poing it gives an eror about being "Unable to handle kernel NULL pointer dereference at virual address" I get the CD error when FSB spectrum is set to .50, I get the ramdisk error when it is set to 1.00
Things I've tried:
I've tested both ram sticks individually.
I've tried relaxing the memory timings, and changing the ram voltage.
I've tried disabling external cache.
Other info:
System temperature: 30 degrees celsius
CPU temp: 50 degrees celsius
I had to manually tweak the FSB to 166 (was being registered at 100) and set the FSB/DDR ratio to 1:1 (otherwise my PC2700 showed a 100mhz clock)
Voltages appear to be within tolerance.
Can anyone suggest what might be wrong? My power supply is rather cheap, but again, voltages look OK in the bios, and would that create such consistent problems? Is it my RAM? Or do I just have a faulty motherboard or CPU?
I've been at this for hours and I'm going nuts. Please help!

qui3ote it's so hard to say just exactly what your rig is going to take to run properly...some ppl spend hours trying different component configurations trying to make them work together only to find out that they have 1 or even 2 components in the "mix" failing at the same time thus leaving them to scratch their heads in disbelievement...I've been there myself...your best bet is to do as the "pro" builders do...
Homework, homework, homework...many of us now look around the net for others who have already built systems around a certain motherboard not being the first pioneers to venture into the unknown...saving ourselves countless hours because we've taken the time to talk to the experienced out there as to what will and will not work...
Some of us who do build a lot of systems for other folx out there take the time to buy different brands of memory, PSU's, CPU's, MB's, etc...and play with different configs in order to find "what works" and then post results in different forums in order to let others know what they've tried and not tried...this usually takes a bit of capital in order to buy what's known as "troubleshooting parts" and can get quite expensive...
To the occasional home builder: The days of buying and building with no problems is long past...with todays high speed systems, a lot of these home builders only remember the brand names that they used in the past thinking that they can go out and buy a really full featured high end MB, cheap generic or "Value" RAM memory, use the same case (usually 3 to 5 yrs old with a PSU in it that couldn't jump start someone's heart if they were dying, much less start up a power hungry high end gaming rig), as well as other peripherals...
Then they head on down to the MB mfg's website (if they even have one these days) and (thankfully not in your case) begin to trash and bash the company about how they have a crappy product, blah, blah, blah...
See where I'm going with this? In any case, as long winded as I've been here, you must now rise above the "occasional home builder" status and approach building with a new outlook as to "how to" and do that homework if you don't want to end up in this boat each and everytime...technology advances and it's up to us humans to advance our thought processes with it...
I wish you luck in your build here...my biggest advice I can give you atm is to go read the sticky posts at the top of the forum for some excellent tips on Memory, troubleshooting, etc, in order to gain some insight into how to do what you're doing...also, as Raven here points out, that PSU is way out of it's league in being able to supply the power needed for the build you're doing...take a step up into the world of high speed computing and lay down some cash for some higher end components that will leave you tearing out less of your hair and give you some peace of mind...
Apacer, OCZ, Corsair, Infineon, and, of course, Mushkin are all decent memory lines that have been known to work with these MB's...DO NOT buy cheap "Value" RAM memory for your board, it's likely to only give you more headaches...Mid to high end memory will cost you considerably more money but will save you countless hours of time trying to troubleshoot which to me is more valuable these days...a PSU with AT LEAST the amperage specs that Raven lists in his post, +3.3v-28, +5v-35A, +12V-18A, or even better is in most cases a requirement these days...and yes you're going to spend 60 to 100 dollars US or more to get one that gives you that spec...sales are a good thing to watch for all of this...
Sorry to go on for so long but I just wanted to give you some insight into the "new age" of computer building! Hope I've enlightened some things for you...if not sorry I rambled on so much *chuckles*
Good luck and let us know if you need any more help!

Strange system hang using rmi

Hi, I read for several hours now, but I can't find a hint what problem I'm experiencing. Perhaps someone has an idea?
I have a small java application (jdk1.3.1_08) which starts a RMIRegistry, binds an object name. It then starts another java application in another jvm using Runtime.exec(...).
Everything fine until here. The second application starts and works fine.
BUT: Now I close app2 and start it again from app1. Basically everything works also this time. But there is a delay at startup from app2 which I cannot explain. App2 hangs for 10 secondes up to 70 seconds, between two debug outputs!!!
Every little hint is appreciated!!
Torsten.

I think the hanging of app2 is not depending on what it actually does. But I try to explain some more, you're right:
App1 is kind of a starter environment, a launch center for several applications. One of these applications is my app2. The reason for using rmi and the second jvm is that I now can use a System.exit(0) in app2 without killing the launch center (app1). When I start app2 standalone from command line without rmi, then it starts without the strange system hang.
What does app2 do?
App2 has a starting time of about 30 seconds (standalone) where several things are initialized. In detail, it is a Swing application using the oracle framework JClient for data binding of Swing components and the oracle framework BC4J for mapping to an oracle database. The system hang when started in the second jvm occurs in the startup process, but not at a specific point in the programm. This means: on PC1 it hangs everytime between the same two debug outputs, on PC2 (a bit faster) it hangs later in the code. Thats the reason why I think, there could be a rmi problem.
What I did not mention yet: The launch center (app1) builds a kind of transfer object which is passed via rmi to app2 in the second jvm.
Does this help to solve my problem? I really run out of ideas what to do...

Odd System Hangs [SOLVED]

I have a cleanly installed Arch (x86) system on a Dell Vostro 1500
Intel 2.5 GHz Core 2
Braodcom Wireless (ndiswrapper)
4GB Ram
250 GB Western Digital HDD (sata)
nvidia 8400 GS 256 MB
1650x1080 Resolution
Built in UVC web cam
I seem to be having these completely random and odd system hangs.
It prevents me from using my computer for more than a few minutes at a time.
When it hangs, its usually what ever process im in gets stuck, i cant kill it completely all the time. Sometimes i can using top as root and sometimes i can using kill -kill but sometimes i cant at all and that is usually when the PPID is 1.
When I try to shutdown or reboot either from in gnome or one of the virtual consoles, it always says something about either the root or home partition unable to be unmounted, that they are still busy.
my partition layout is such:
sda1 NTFS Vista (I have to have it because of stupid itunes/iphone)
sda2 ext2 boot
sda3 xfs root
extended:
sda5 xfs home
sda6 swap swap
my ntfs partition is about 50GB and when i boot into vista i dont get the same hangs, so i don't think its a hard drive issue (but could be an partition issue)
boot partition is something like 300MB
root is something like 12 GB
Home is something like 70 gb
and swap is about 2gb
It does not matter whether or not im in gnome since if at log in screen, ill hit ctrl+alt+f1 and switch to a consol and do something as simple as like update the computer and ill cause it to hang sometimes (but not every time its too unpredictable)
When in gnome however, most applications refuse to launch and sometimes even close. The gnome-panel and some (like the system monitor) lock up but things like cpu freq scaling continues to work as does log out and the menu.
i have also had issues with the latest (-3) nvidia driver and can only get 1680x1050 resolution using the open source nv drivers (haven't had a chance to build from aur the beta drivers yet since there is an issue with the nvidia-utils-beta package) but i don't think this is causing it.
i used the western digital tool to do a hard drive scan, and it didn't find anything in the quick scan but it is still running the full scan.
I suspect it might be due to some package upgrade, i was running arch before the reformat and it was causing me to have the same issues.
i have kicked my personal Ubuntun (and derivatives) additional because of Arch's rolling release cycle so that's why i would rather put up with it for another week to figure this out!
Let me know if there is any log files i should post or anything that way i can get this fixed! And thanks in advanced (even to those of you who will probably only comment to make fun of vista, it still will keep my thread alive! )

b,
The install was from my original Dell XP Pro-SP1 'Reinstallation' CD along with the complete MS XP-SP2 download that I burned to another CD. I also had all the latest Dell drivers from their website burned to a CD. Install went as follows:
- Format HD
- Install XP Pro SP1
- Install SP2
- Install Dell Drivers
- Obtain any MS patches from their site
- Install Office
- Update Office from the MS website
- Install iTunes
- Tweak MS settings
- Install many software programs
- Make an interim Image of system and store to ExHD
- Install other software programs (mostly security programs)
- Make another 'complete' Image to ExHD
- Restore backup data and music
After additional testing last night, I determined that it is not iTunes at all (or to blame). I get intermittent hangs/freezes/pauses in other media players (WMP, etc.).
Seems that something is causing the 'System' process to periodically jump up in CPU %age (though not more than 30-50%). Even this relatively small amount is enough to pause the playback of music or video, hang the mouse movement for a brief moment, or delay a menu opening. All very subtle - you have to be looking for it to notice (except with real-time audio-video, which is quite noticeable whenever this happens).
I had this problem a year ago, which is why I reimaged then and stayed with SP1 on the advice of Dell and Webroot. I'm stumped as to where to look for the culprit. Every time I go back to the original HD with SP1, everything runs smoothly. Some sort of system call is generating this complete pause....
I'll be limited in my Internet ability for the next several days, so I may be out of touch until Friday. I'll keep testing and playing with the limited equipment I take along....
Any thought you or others want to toss out, I'll attempt when possible.
Thanks!

Firefox 3.6 when I open a SWF file, a wrong mouse click, it show a recursive open window until the PC resource is used up or the system hang up, I try to reinstall firefox but not solved.

Windows XP SP3, flash player 10.2, Shockwave 11.5.9.240 , when I open a SWF file with firefox 3.6.15, it shows some options to choose action and I made a wrong click. The firefox nightmare is a "open recursive windows" until the system hang. When I use Internet Explorer 8 to open it, it is fine, Try to uninstall firefox and reinstall it, but in vain, how can I restore it?

You don't have the Shockwave Flash Player installed for Firefox. You may have the ActiveX version installed for IE, but Firefox needs the Plugin version. And Shockwave 11.5.9.240 that is installed for Firefox isn't the same thing.
1.Download the Flash setup file from here: 
[http://fpdownload.adobe.com/get/flashplayer/current/install_flash_player.exe Adobe Flash - Plugin version]. 
''Or maybe get the previous '''r102''' version from here. IMO, there's problems with the latest version of Flash.'' 
http://kb2.adobe.com/cps/142/tn_14266.html 
Save it to your Desktop. 
2. Close Firefox using File > Exit 
then check the Task Manager > Processes tab to make sure '''firefox.exe''' is closed, 
{XP: Ctrl+Alt+Del, Vista: Shift+Ctrl+ESC = Processes tab}
3. Then run the Flash setup file from your Desktop.
* On Vista and Windows 7 you may need to run the plugin installer as Administrator by starting the installer via the right-click context menu if you do not get an UAC prompt to ask for permission to continue (i.e nothing seems to happen).

System hanging when it runs out of memory

Hello,
my system has a finite amount of RAM and swap (it doesn't matter, to my purpose, if it's 16GB or 128MB, I'm not interested in increasing it anyway).
Sometimes my apps completely use all the available memory. I would expect that in these cases the kernel kills some apps to keep working correctly. The OOM Killer exists just for this, doesn't it?
What happens, instead, is that the system hangs. Even the mouse stops working. Sometimes it manages to get back to life in a few seconds/minutes, other times hours pass by and nothing changes.
I don't want to add more memory, I just want that the kernel kills some application when it's running out of memory.
Why isn't this happening?
Right now I'm writing a bash script that will kill the most memory-hungry process when available memory gets below 10%, because I'm sick of freezing my machine.
But why do I have to do this? Why do I need an user space tool polling memory usage and sentencing applications according to a cheap policy? What the hell is wrong with my OOM Killer, why isn't it doing is job?!

Alright, you won, now quit pointing out my ignorance
Your awkish oom killer is a lot cooler than mine, switching to it, thanks!
I did some testing (initially just to test the oom killing script) and found out that if a program tries to allocate all the memory it can, it gets eventually killed by linux's oom killer. If instead it stops allocating new memory when there are less than 4MB of free memory (or similar values) the OOM won't do anything, and the system will get stuck, like if a forkbomb was running.
That's it, this program with MINSIZE=1 will be killed, while with MINSIZE=4MB will force me to hard reboot:
#include <string.h>
#include <stdlib.h>
#define MINSIZE (1024*1024*4) // 4MB
int main( )
int block = 1024*1024*1024; // 1GB
void *p;
while( 1 ) {
p = malloc( block );
if( p ) {
memset( p, 85, block );
else if( block > MINSIZE ) {
block /= 2;
return 0;
Guess I'd need to go deeper to understand why Linux' oom killer works like that, but I won't (assuming the oom killing script will behave).

While upgrading the system hanged

I was prompted to upgrade & the software downloaded, but while starting the system hangs up

after the software upgrade was installed the system was booting up and it crashed
Now when I try to start the system it asks for the password and after entering the password the systems seems to start but halfway through the process, the laptop shuts down on its own

Lion 10.7.1 system hangs after reboot

Strange, I have just updated to 10.7.1 (via SW update) on my Macbook Pro and now the system does not boot. It restarted and now hangs since minutes with the spinning wheel on a grey screen. Anyone experienced this, too? Any solutions?
Thanks a lot.
Tom

Regarding the occasional system hang on reboot people are experiencing. I have two troubleshooting suggestions to help you get to the login screen, but aren't solutions to the problem of whatever is causing the system hang. 1) I find my hangs are usually solved by removing my USB devices from the 2 USB ports (via USB hubs) and rebooting. 2) Furthermore, if I boot into verbose mode (holding command+v right before the chime) (sometimes after removing the USB devices, sometimes not), that usually helps the boot process along, either due to just chance (I don't know why booting into verbose mode would help it surmount the initial hang, but it seems to work sometimes) or some other reason.
Good luck.
Yeah that better be one big fat good luck there, because that advice is not going to help anyone that is having this problem. Not one little bit. Some kind of magic that Verbose Mode casts will fix it? Uh, no. That would be a figment of your over-eager imagination, Verbose Mode doesn't change anythig. Oh and by the way, in order to get to this stage in the probelm, you would have had to use verbose mode to get the error message. I can only assume that you sir are the real troll here, because our friend above asked a question that is worth merit and consideration, given the compatibility disaster that Apple has on their hands. To call it a disaster is not in the least bit an exaggeration.
We're going to have to ignore This is not an "occassional system hang", this is a serious problem affecting my MacBook Pro 17" and my iMac 27"., and it occured on both of them for me after installing Lion Server.

Hibernation does not work - System hangs

Hi, I have T41 laptop with Windows XP. When I tried Hiberation option, system hangs ( message - hibernating......) and does't hibernate. Can you help me with this..
thanks
-G
Solved!
Go to Solution.

Right,
Based on the info you supplied, there's one glaring issue that prevents you from using the hibernate feature successfully - the low disk space. Hibernation requires a minimum of 3GB (mostly 3.5GB as a minimum depending on what you're running - processes, etc).
Alas, one of the only ways to fix that is to upgrade to a larger capacity hard drive or remove some software to make space.

System hanging on shutdown

The home directories on my system are on NFS.
Most of the times, when users log out of their graphical session, some of their processes keep running (for instance /usr/bin/nepomukserver for KDE users and some processes related to pulse or to chromium).
When shutting down the system, arch scripts first try unmounting network filesystems, and this fails, since /home is busy; then they send a SIGTERM to processes, and this fails as well (I believe it's because the network has been halted but /home hasn't been mounted), then the system hangs while unmounting non-API filesystems.
If, before shutting down, I manually kill the user processes (nepomukserver, pulse, chromium, ...), arch is able to shutdown as expected.
Am I the only one affected by this problem?
How am I supposed to solve it?
I'm thinking about writing a script to terminate (`kill` and then `kill -9`) any process using /home (`lsof /home`), but this looks like a terrible hack...

So, since I couldn't find any other solution, decided to write a script (an init script to add to the DAEMONS array) that kills the processes using /home while halting the machine...
If anybody will ever need it, here it is:
/etc/rc.d/pathliberator
#!/bin/bash
# Path Liberator
# kills processes that are using a given path
DAEMON=pathliberator
. /etc/rc.conf
. /etc/rc.d/functions
[ -r /etc/conf.d/$DAEMON ] && . /etc/conf.d/$DAEMON
case "$1" in
start)
stat_busy "Starting path liberator"
add_daemon $DAEMON
stat_done
stop)
success=true
for path in ${PATHS_TO_LIBERATE[@]}
do
pids=$( lsof -Fp $path | sed -rs "s/^.(.*)$/\1/g" )
if [ "$pids" == "" ]
then
status "$path was already free" true
continue
fi
# kill -TERM
stat_busy "Liberating $path"
kill -15 ${pids[@]} &>/dev/null
pids=$( lsof -Fp $path | sed -rs "s/^.(.*)$/\1/g" )
if [ "$pids" == "" ]; then
stat_done
continue
fi
stat_fail
pids=$( lsof -Fp $path | sed -rs "s/^.(.*)$/\1/g" )
# kill -KILL
stat_busy "Liberating $path with SIGKILL"
kill -9 ${pids[@]} &>/dev/null
pids=$( lsof -Fp $path | sed -rs "s/^.(.*)$/\1/g" )
if [ "$pids" == "" ]; then
stat_done
continue
fi
stat_fail
success=false
done
status "Paths liberated" $success
if [ $success ]
then
rm_daemon $DAEMON
fi
restart)
$0 stop
$0 start
echo "usage: $0 {start|stop|restart}"
esac
exit 0
/etc/conf.d/pathliberator
# Parameters to be passed to pathliberator
PATHS_TO_LIBERATE=(/home/)
It seems to be working, although didn't deeply test it...
My DAEMONS array now looks like this:
DAEMONS=(hwclock syslog-ng cpufreq network crond nscd dbus rpcbind nfs-common netfs pathliberator gpm sshd @ntpdate alsa fuse gdm avahi-daemon)

System Hangs after adding Storage :(

First dont jump on me for mentioning a 4800 this is storage related.
Solaris 8
Brocade 3850(SUN Branded)
SUN Samfs(4.2.8, running 5 months)
EMC Clarion(Old existing and always seen in config)
Infortend FC-SATA array(Newly added)
I have added some FC-SATA drives to my 4800s. The process of adding these drives was done by a 'cfgadm -c configure <Controller #>'. Following this the disks are seen, striped and shared with SAMFS. All is good at this point.
During reboot the systems hangs just after the boot message of "System is coming up". I think it is at the point of finding mount points and doing an 'fsck', but the system never completes(+45 minutes).
When I drop back to the original configuration prior to the 'cfgadm' the system then boots just fine, but I then need to do 'cfgadm -c .....' to see the drives and mount my SAMFS partitions.
Any ideas?

SimonM
The disks can be seen when I attach the storage with a 'cfgadm -c configure <controller #>' and the system up and running. After dynamicly attaching the storage I can create filesystems, use SAMFS to share the filesystem out, and all is good across all machines.
I only have an issue later in life when a reboot(hate for a panic) occurs. Some sunsolve/goggle'ing found some old document that were very dated that pointed to the path_to_inst and fiber not playing well.
I am not 100% sure that the system has hit the mount/fsck processes or not but it is the next sequence in the boot process. I know it is storage/config related because (1) adding the new disks is the only thing that changed on the system, (2) returning the OS back to its original configuration before the disks being added allows everything to boot fine. I was just looking for some pointer of where to begin troubleshooting.
I will keep everyone updated. Like I said I only get a couple of hours every month if I am lucky.
