Periodic hangs in mut_win32.c
I am getting frequent hangs in mut_win32.c at line 130 to 223;
loop: /* Attempt to acquire the resource for N spins. */
goto loop;
Is there (maybe, hopefully) a reasonably simple intercept point that I can insert some printf's to see what is happening.
Seems like it always happens (when it happens) while doing an open after a previous run in which everything closed normally.
Have been unable to pin down a particular sequence that is causing it.
I am on WinXP with BDB 4.6.21
Thx,
Jim
OK. Here it is. Looks very similar to the db_verify version. I am running a checkpoint every second only to force the deadlock. My test pgm does a few opens, so it is pretty quick to lock up with all the checkpoints.
I'll try to reproduce it with what I call a "native" bdb app (one without all my pgms baggage).
I added some verbose logging options also which is at the end of this post.
Before the run, I deleted the entire BDB home dir, including __* files, all db files, and log files.
Thx,
Jim

SRKIM: GL open period 시 hang이 발생할 경우
PURPOSE
GL 에서 open period 시도 시 hang 이 발생하여 더 이상 진행이 되지 않을 경우의 해결책을 제시한다.
Problem Description
GL 에서 open period 시도 시 hang 이 발생하여 더 이상 진행이 되지 않는 경우가 있다.
Workaround
N/A
Solution Description
1. 다음 sql 문을 수행 한다.
Select * from GL_CONCURRENCY_CONTROL
where concurrency_class = 'OPEN_PERIOD'
and CONCURRENCY_ENTITY_NAME = 'SOB: '||'&SoBId';
만약 set_of_books id 가 12 라면 아래와 같이 수행 하면 된다.
Select * from GL_CONCURRENCY_CONTROL
where concurrency_class = 'OPEN_PERIOD'
and CONCURRENCY_ENTITY_NAME = 'SOB: 12';
2. 만약 해당 sql 에서 concurrency_entity_id 가 –1 이외의 것이 있을 경우 아래 sql 을 수행 한다.
Select request_id, request_date, status_code, abc.meaning status
from FND_CONCURRENT_REQUESTS,fnd_lookups abc
where abc.lookup_type = 'CP_STATUS_CODE'
AND status_code = lookup_code
AND request_id = &request_id;
3. 위의 sql 수행 시 status 가 running 중인 것이 없어야 한다.
4. 확인 완료 후 아래 update 문을 수행한다.
Update gl_concurrency_control
set concurrency_entity_id = '-1'
where concurrency_class = 'OPEN_PERIOD'
and concurrency_entity_name = 'SOB: <sob id>'

High CPU load after firefox 18.0 update, causing periodical hang
Hi, I am basically getting crazy here after the update to firefox 18.0 yesterday.
Firefox periodically causes very high CPU load, which makes it impossible to use.
http://img805.imageshack.us/img805/702/firefox18.png
The problem does not occur immediately after restart, but you can already see the spikes of CPU load in the taskmanager with a peak of ~4%. After a couple of minutes this will go up to almost 50% utilizing a whole core and causing the hangs.The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Mail & Exchange 2010, periodically hangs or stops receiving
Subject pretty much says it all. The weird thing is I can login with OWA or check on my iPhone and see new messages. Why would iPhone be able to download messages when Mail can't?
I have no problem with the connection on the machine running Mail. At the same time Mail won't download anything, I can open Safari, login to OWA, and see new messages.After having the same error ("opening mailbox - Requesting latest information" - hang) and fighting for months on my Mac (Lion) to solve it, including writing angry bug reports to Apple - I think I finally found the source of the problem:
There was an old (invalid) certificate installed in Exchange (2007, in my case), enabled for SMTP.
Nobody seems to care about this - including Snow Leopard Mail, Outlook and all iOS devices - but Lion Mail cared, and just stuck. Typically after some time - maybe sleep/wake or just a couple of hours - Mail was stuck and did not receive any new mails anymore, until I Force Quit it.
I got the hint from another forum (somebody suggested changing the properties in the locally installed certificates in Lion - but this was not the solution) and after seeing the question popping up once in Mail Preferences (do you want to trust this (old) certificate).
After removing the old certificate from Exchange (good luck with this admin user interface - no wonder we did not notice it) - everything works ok for me, already a day without any hangs.
Hope it helps! (Let us know the outcome...) -
Intel HD 4400 - Intermittent/Periodic Hang
I am running Arch on a Lenovo X240 with an Intel i7-4600U CPU with Intel HD 4400 graphics.
When pushing 2 screens, the 1920x1080 on the laptop and a TV running 1920x1080 to watch a movie, the entire system will periodically lag. By this I mean, that when running VLC or flash within Chrome/Firefox there will be a slight pause every 1-2seconds, very consistently. I have tried messing with /etc/X11/xorg.conf.d/20-intel.conf to no avail, it is displayed below. I am wondering if there are any other avenues I can try? If you need any information, let me know

My system is periodically hanging
This has been going on for a long time, but the last time I tried to diagnose it I didn't get far. This time, though, journalctl shows me a potentially helpful message:
Oct 16 17:15:23 homura kernel: BUG: unable to handle kernel NULL pointer dereference at 0000000000000001
Oct 16 17:15:23 homura kernel: IP: [<ffffffff811a600b>] kmem_cache_alloc+0x6b/0x170
My system has been hanging after a few hours of use, several times a day, for a long time now. This is the last thing journalctl shows the last few times it has happened.
Any ideas? Googling around hasn't been very useful.jasonwryan wrote:

I'm going through the tedious process of bisecting the kernel now...
Thank you! However, I'll note that this has been a problem since 3.13 and I couldn't solve it back then. I would help you bisect but the last time I tried, I couldn't get a custom kernel working with nvidia. -
System Hang, kernel panic.
Hello list,
Doing some independent research into an issue we are having here. We have 21 x4540s running 5.10 Generic_141445-09. They are used as NFSv4 servers to front-end servers. The x4540s that are used for mail (postfix+dovecot) periodically hang. The others do not.
Since they hang, it has been difficult to diagnose what the issue could be. We have "set pcplusmp:apic_panic_on_nmi=1" in /etc/system, and I try to issue "set generate_host_nmi = true" in ILOM, but it appears to be too dead to manage that.
The only symptoms we have in the logs are:
Jul 24 07:50:49 x4500-11.unix inetd[292]: [ID 702911 daemon.error] Unable to fork inetd_start method of instance svc:/network/nfs/rquota:default: Resource temporarily unavailable
Jul 24 07:51:09 x4500-11.unix last message repeated 1 time
Jul 24 07:51:15 x4500-11.unix sshd[343]: [ID 800047 auth.error] error: fork: Error 0
Jul 24 07:54:25 x4500-11.unix last message repeated 4 times
A few times I have had a working shell connected when it happened, still running top, which shows it is not out of memory, not even close. No process has gone wild (pretty much just nfsd running). It would appear that it can't start new processes, but not due to lack of memory. Eventually it grinds down to a halt, including console. If I try to run "reboot" (or even reboot -d) it tries to reboot, but fails (just hangs). ILOM reset /SYS will bring it all back again.
Currently, this happens 2-3 times a month. Funnily enough, always at night. What does run at night is a recursive zfs snapshot. It usually dies sometime after that. The process that always gets the first error is rquotad. But that could just be because it is constantly queried.
Not much to go on alas.
Then one day, we got a panic dump. Is it the same problem, or something unrelated? Hard to know, but IF it were to be related...

Can I use mdb to dump all the currently-used-stack memory, and collect that data to see if there is a leak? I could also double the stacksize and see if the period between trouble also doubles.
Any other suggestions which may help in locating the troubles we are seeing?SteveS,
Thanks for the reply. I have handed it off to the local support, and believe they have forward it to Oracle Japan. Possible, it goes through a lot of language translation, so it is a little like playing Telephone.
I was trying to decipher your ::cpuinfo -v information to see if I could determine if we were having this issue. But I am unsure what to look for in a non-healthy system.
This is the output I get

ENABLE As for "ps" we only have 42 procs, and threads the biggest process is "nfsd" (can use up to 1024, but hovers around 300). We are not hanging (or even considering the fork error) due to normal resource limits.
While waiting, I am poking around in the dump to see if we can find anything interesting. Last time, Telka managed to find out about the OpenOwner lock leaks, which was encouraging. -
Hangs, slow shutdowns and restart, spinning ball opening and closing apps
I am experiencing random hang ups and slow wake up and shutdowns.
I will be typing something and nothing appears then all of a sudden the text will appear. The cursor will periodically hang up, applications take along time to open and close and I seem to get the spinning ball frequently. System preferences is slow to open. The problems seems to correct itself if I restart.
In addition, it takes forever for the DVD to recogized a CD or DVD disk and show the icon on the desk top.
I have been monitoring various posts related to this problem and there does not seem to be an answer?? Is Apple aware of these issues. I have done everything from resetting the PRAM to running disk utilities, unpluging the machine, re-installing software, etc... Nothing seems to work...I called tech support and been the Genius Bar....It seems to get worse the longer the computer is on....HELP...dralexander wrote:

like an over-temperature problem. Try smcFanControl.

I downloaded and purchased Power Tools for my BlackBerry Z10 primarily for the Message Filter service.
I configured a number of filters to remove spam which seem to work, however it periodically hangs requiring it to be stopped using the device monitor and restarting.
it gets regular updates from the makers of it is up to date, I was just wondering if anyone else was using this app and they were experiencing the same hangs. If so, if they had any cures for this.
ThanksWell I got a response very quickly, but it was only to check that I had not installed toolbar wallpaper, which I hadn't.
I noticed that the company ToySoft also have a free product Power Bot which restarts Power Tools if it crashes. I've installed it to see if it cures my problems, so far it seems to be cleaning up email as intended without having to do it manually or restart. I don't know if it's buggy or that the OS causes it to crash periodically (possible since other programs suffer the same hangs or crashes) . As Power Bot is also a headless app I guess this may also crash!

I am using Window 7. What else would you like to know?
I might have discovered the solution without starting over with all your places and bookmarks.
Right after i installed 7.0.1 over a week ago,every 10-30 min When i would be watching videos online, it would freeze for 20-30 seconds. Firefox would say ( Not responding) both firefox and the plugin container process would be very large memory files. I tried to go back to Firefox 5.0. No avail it would still freeze.I tried to disable the plugin container . no good. I tried to adjust memory or cache or plugin settings in “about:config”.Nothing fixed it!
I finally discovered why my Firefox 7.01 was periodic hanging fix. It is something to do with some of your personal files. download this this add on and install it
https://addons.mozilla.org/en-US/firefox/addon/places-maintenance/
or you can Google "places maintenance Firefox"
After you install the add on, restart Firefox.go to "tools", then "add ons" and then click “extensions” tab ,then click' options" on the "places maintenance" entry. choose "ALL' or just "expire" and hit "execute", then wait until its done., restart Firefox. should be fine then and all my bookmarks, customizations ,settings, and history stays untouched!
After i did this my Firefox did not freeze once for over 3 days straight. Might not work for everyone. I already read that Mozilla is aware of the problem and are working on a fix it in the full version of 8( the 8 beta did not fix the problem for me) . But they said this is a good temporary fix at least,( might be permanent)
For me at least ,Firefox works fine in 7 now. perfect actually.And many people i saw on similar forums had similar problems.
Enjoy. Hope this helped -
My firefox stops responding and fades for about a half min almost every hour, OR MORE often
My firefox stops responding and fades for about a half min almost every hour, OR MORE often.
I am typing a message or information, the screen fades to about half bright. the curser freezes in place and no key responds.
The information bar at the top of the page says "firefox not responding" in about 30 seconds it restores and continues as tho nothing happens.I might have discovered the solution without starting over with all your places and bookmarks.

How do I restore mail from Time Machine after a clean Yosemite install?
I've been having various performance issues with my iMac recently (wifi keeps dropping off, scan functionality on my multifunction printer stopped working, whole system periodically hangs) so decided to do a clean install of Yosemite. I also have a MacBook Air, also running Yosemite, and on which I have no issues with the wifi, printer or system performance.
Before doing the clean install, I made sure I had a current Time Machine backup. The process appears to have worked so far, but I have run into an issue restoring my mail. I think it best if I describe how I have restored my documents and then I can show at what point I run into a problem.
To restore documents, I opened Time Machine, used the keyboard shortcut command-shift-C to show the backups prior to the clean install, and then selected the documents I wanted to restore. This was simple and worked perfectly.
To restore my mail, I opened Mail, selected 'Enter Time Machine' from the shortcut menu at the top of the screen and then used the keyboard shortcut command-shift-C to show the backups prior to the clean install. This is where I got stuck as command-shift-C is a default shortcut in Mail that shows the colours dialog box. Hence I have been unable to view the correct backup. The backup I want is listed on the right hand side of the screen in Time Machine, but I can't work out how to select it.
I thought changing the shortcut in Mail might work, but I couldn't find a way to do that either since it is not listed in the Keyboard section of System Preferences.
Any ideas gratefully received.

Mail 8.1Hey there,
It sounds like you're still having trouble exposing the proper library folder. You can use the following terminal command to do it globally (this will show all hidden files)
Open Terminal from your appliications folder and copy/paste this into it:
defaults write com.apple.finder AppleShowAllFiles TRUE (press return)
**After that last line you'll need to restart the finder so use:
killall Finder (press return)
Now if you enter Time Machine the correct Library should be visible. To re-hide your hidden files repeat the process above but replace TRUE with FALSE, then use the "killall Finder" again.
I agree with the commenters above, you should restore the Mail library to the desktop and then re-import it to Mail. This is how I was instructed to solve this problem by Mac help, who I chatted with online for quite a while before they figured it out.
Hope this helps -
How to purge data in a global temporary table from another session
I've got a problem with vendor-delivered web-based software (jdbc) that periodically "hangs." When that happens, I have to kill the database session before retrying the process. This "workaround" does NOT clean up the temporary tablespace. Is there anyway (outside of bouncing the database) to truncate temporary tables regardless of sessionid? Thanks.
In 8i the space used by temporary segments is not dropped in a temporary tablespace. The space is available for other queries or temporary tables. This avoids the costs of allocating and releasing space for temporary segments.

Hi. I have a Mid-2011 Mac Mini with 8GB of RAM. I have an SSD installed in it as the primary drive, along with another internal 2TB drive and an external USB 2TB drive for media. This machine is mostly used as a media server and player. It's been running Mountain Lion since I bought it (refurb) last year. I upgraded to 10.8.3 as soon as that came out, and was running for a while without any problems. This evening, though, I started to notice some problems.
The main issue is that the CPU (well, one core) seems to be constantly under load. Under Activity Monitor I'm watching the system load (but not user load) hover between about 8% and 12%, all of the time. But looking at the program list, I don't see anything taking up more than about 2% of CPU, and that is taken up by Activity Monitor itself.
The annoying way that this manifests itself in the UI is that if I'm just randomly moving the cursor around in a circle, I can watch it periodically hang and freeze for about half of a second every 3-4 seconds or so. Meanwhile, everything else on the system also seems to freeze up for about half a second at the same time, which makes watching Netflix extremely irritating. (With Netflix the sound plays as normal, but the video freezes briefly every few seconds - I verified this in both Firefox and Chrome so I doubt it's a browser thing.)
I've already tried some troubleshooting steps myself. (None of this has worked yet.)
I saw a lot of messages in console about "mdworker deny mach-lookup com.apple.ls.boxd", which googling around for led me to this page; per the instructions there I booted into safe mode, waited a bit and rebooted, and now I don't see those messages any more. (I didn't mess with the sandbox.sb file, about which, really? Apple implemented this in Scheme or something?) Just to be on the safe side, though, I disabled Spotlight indexing with sudo mdutil -a -i off.
I opened Disk Util and ran a verify on all three disks, no errors. I found one or two permissions that needed repairing on the startup SSD and repaired them. The problem persisted. I also cleared out my caches with Maintenance while I was at it.
As a side note, even when I rebooted in safe mode, I was still seeing the same behavior (periodic half-second mouse freezes, system CPU averaging a constant 10% or so in Activity Monitor).
I also spent some time reading this other thread which looked like it had some very useful advice (unlike that poster, though, my Spotlight processes aren't crashing). So I went ahead and followed Linc Davis's first set of instructions in that thread. Here's what I've got for steps 1 and 2.
1. Activity monitor
Highest-CPU process is Activity Monitor at about 1-2% CPU
CPU: User 1%, system ~10%, idle ~90%
System memory: Page outs 0, swap used 0 bytes
Disk activity: Reads in/sec 0, Writes out/sec 0 (these infrequently spike up to about 40 or 50 max)
2. System log
I put up a gist for this here. It's my last 50 messages or so, probably some are coming from the most recent reboot. I can see the "IOHIDSystem cursor update overdue. Resending" messages which I presume are linked to my cursor freezes, but nothing else looks obviously suspicious to me. The stuff about "menucracker" is down to MenuMeters; I uninstalled it and rebooted at one point just to check, but it didn't seem to make a difference so I reinstalled it.
As far as kexts go, the only one I had that wasn't Apple was SoundFlower. I actually need that one, I use it to stream files from Plex, but I went ahead and uninstalled it anyways, and it didn't make a difference. My launchd lists start up sickbeard, sabnzbd, and plex, but I've manually quit all of those and the problem persists, so I highly douby any of them are to blame.
Any advice greatly appreciated. Is there a better way that I can see what exactly is causing the high system CPU load, like can I list processes by number of kernel calls or something? I did try top and ps but I didn't see anything obviously different from Activity Monitor in their output.Nope, I don't have a "/Users/charon/Library/Mobile Documents" directory, let alone anything underneath it. Is that like an iCloud thing or something? I tend to avoid the Apple-supplied services when I can (I don't use iTunes either unless I can help it).
As an update, as of about two days later this problem seems to have solved itself. Possibly sleeping and waking did something to it (though that seems unlikely given how many times I rebooted), or else there was just some long-*** kernel process that finally worked itself out. But my system CPU is back down to normal and the cursor freezes are gone.
??? it is a mystery! ???
