Jobserverchild.exe process hanging

Hi
We have installed a new implementation of XIr2. Note that we have an existing implementation which does not do this. We have a setting on the deski job server of Max Jobs Allowed =2. Each time a report is run, it opens a jobserverchild.exe process in Task Manager. If we schedule another report while the first report is running, we get another jobserverchild.exe process. If we schedule multiple reports concurrently, these will continue to use the 2 jobserverchild processes. If all these reports complete, then we schedule another report, the jobserverchild process hangs, and the report stays at status Pending in infoview. If we view the process in Task Manager, the Mem Usage does not change, which indicates the process is hanging. This is causing us severe problems.
Help pls.

Use following method.
u2022 -maxChildReqs <N>
Sets the maximum number of jobs processed by one job server child
before it shuts down and restarts (in case you want a to use a
number between 1 [OUTPROC] and 100 [MIXEDPROC])
Job server children will also automatically shut down if left unused for a
period longer than 2 hours.

Win7 x64 itunes*32.exe process hanged up and window not open

sry,my english not good.
windows 7 x64 and itunes 10.5, after install, itunes*32.exe(Not AppleMobileDeviceService.exe) process hanged up , cpu(1/4 cores) up to 100% .

Sounds stupid, but this will actually work.
1. Quit iTunes.
2. Start an elevated command prompt (Start Menu -> All Programs -> Accessories -> Right Click "Command Prompt" -> "Run as Administrator")
3. Once in the command prompt, type "netsh winsock reset" and hit ENTER.
4. Restart iTunes.
Problem solved.
At least this fixed it for me on my own Windows 7 x64 installation. I had AppleMobileDevice.exe, APSDaemon.exe, and iTunes.exe all at 25% CPU simply from opening up iTunes.
25% CPU for me is 100% CPU per core since I have 4 cores.

The 'JobServerChild.exe' processes with ID '6632' has been running on this

Hi team,
Automated tiket is being generated for the below following issue.
can any one suggest me how to move forward to solve the issue
The Windows Process Monitor script has determined that the 'JobServerChild.exe' processes with ID '6632' has been running on this computer for longer than the maximum acceptable time of 18000 seconds (5 hours).
Thanks
Murthy

Hi Murthy,
It sounds as though you have a schedule which is long running or the jobserverchild.exe process has become orphaned.
If you check with the Instance Manager you chould be able to see if any schedules are taking much longer than usual. The Task Manager on the XI3.1 server will also show you if any jobserverchild.exe processes are hung i.e. not consuming any CPU\memory - once located you can kill the process.
I would also recommend that you apply the -type OUTPROC switch on the Job Servers to ensure that in future the jobserverchild.exe processes are killed upon completion of the schedule task.
I hope this is a very helpful answer to you.
Kind regards,
John

Acrobat X intermittently won't launch, multiple Acrobat.exe processes hanging in task manager

Apologies if this is in the wrong community area - I was unsure where it belongs.
This is an intermittent issue, but does happen several times a day.
Regardless of what method is used to launch Acrobat (double-clicking a PDF, clicking the shortcut in the taskbar, selecting Acrobat from the start menu), often the application won't launch. Upon investigation, task manager shows multiple instances of Acrobat.exe, although the application is not running (see the image below). Ending all Acrobat.exe processes does allow Acrobat to launch.
Any thoughts as to what might be causing this, as well as a more permanent fix? The workaround of constantly ending multiple processes is becoming cumbersome.
We are running Acrobat X Pro in Windows 7. I also have several CC 2014 apps installed (as well as a couple of earlier versions required for plugin functionality).

This happens all the time in my company with several installs of Acrobat.
The only way to fix this for us is to end each process in Task Manager as you have pointed out.
It is very time consuming in our workflow as we each operator deals with hundreds of PDFs daily, and has to do this End Process procedure several times a day.
We have done several tests and nothing seems to stop this from happening.

AcroRd32.exe process on Application Server Hanging Up

I run a print job in a reporting system that utilizes Adobe Reader 9.5 for Windows Server 2008. When the job runs, the AcroRd32.exe process hangs up, which prevents me from running anymore print jobs. I cannot end the process via Windows Task Manager, or even a force kill from cmd. I've had this issue for a while and I'm at a loss. I do notice that there is a adobe reader file that is under my common files (created from my print job) that I cannot delete because it says the file is open . I believe this is why the process is hanging up. It's weird because I can't even delete or close it from the server's 'Share and Store Management' because it doesn't show open.
Can anyone help me?
Does Adobe have any tech line I can call to debug? I'll pay.

The first thing I would try is to update to 9.5.5, or 10.1.8, or 11.0.4
If you want to contact support, go to http://helpx.adobe.com/contact.html?product=acrobat&topic=using-my-product-or-service and click I still need help.

Autoconfig hangs on LSNRCTL80.EXE process | windows

Hi all,
I'm a newbie here. First thought I'd put this thread under the windows subforum, but couldn't find an appropriate section there. I'll give it a shot here.
In a windows environment autoconfig hangs on the LSNRCTL80.EXE process being active.
A TNSLNSR80.EXE is spawned but LSNRCTL80.EXE hangs and autoconfig will only continue if the LSNRCTL80.EXE is killed by hand.
After autoconfig finishes, the LSNRCTL80.EXE service has to be started by hand again.
As we're working on automating a cloning process, the idea behind my question is to not having to interfere during the cloning process. The idea of having to set your alarm to kill the LSNRCTL80.EXE in the middle of the night is not too appealing.
Funny thing is that when you use remote desktop + console this problem does not occur, but if you use remote desktop without console, the LSNRCTL80.EXE hangs and has to be killed for autoconfig to finish.
Any ideas where to find the solutions to this?
I'd appreciate any ideas on how autoconfig can be run within a cloning process without having to manually interfere by killing the LSNRCTL80.EXE.
And/or any ideas on why this problem does not occur within the remote desktop + console setup?
Thanks all in advance for your time.

Hi,
This is a known issue as you need to run AutoConfig on the server itself (not from a terminal client) -- See (Note: 260365.1 - Adconfig.cmd Hangs When Starting Apps Listener) for details.

Hussein

Numerous Explorer.exe processes run on Server 2012 reboot causing server to hang

I have recently installed Server 2012 as a Domain Controller. AD, DNS and WINS services as well as Hyper-V manager.
I am facing a very strange issue which does not occur every time I reboot the machine (but on most times).
The machine boots to Windows and hangs, I can notice a large number of explorer.exe processes (that start without any user intervention). The server hangs completely and I am unable to kill the processes manually.
I have to restart the server remotely via shutdown /i.
On reboot the server works fine, If i reboot the server by switching off the hardware manually the same issue may occur..
Any idea what might be causing this behaviour?
Thanks and Regards

Hi Carlos082,
I would recommend you to check the event logs which generated during the server hangs.
Please also try to set up a Performance Monitor log and let it run for a while. At the very minimum, add the counters for Memory, Process, Processor and System. The length of time that you need to let it run will depend on how long the system
takes to hang (assuming that this is happening repeatedly). Set the interval so that you can capture at least a hundred samples over the life of the log. Any low memory condition should be readily apparent - especially if it is a steady leak.
Finally, follow the steps in
KB Article 244139 to prepare the system to capture a complete memory dump for analysis if needed.
To troubleshoot the server hangs, please follow this article:
Troubleshooting Server Hangs - Part One
I hope this helps.

When closing Firefox (v:3.6.13), using the red "close" button, the firefox.exe process remaines at top of the "Windows Task Manager" window and continues to use the majority of CPU time.

After an attempt to close the Mozilla Firefox page, on every occasion, the firefox.exe process is found at the top of the list when ordering the listed 'processes' by CPU time... even though the web page is gone.
If an attempt is made to restart Mozilla, the system declares that the current Mozilla process should be closed.
If the firefox.exe process is explicitly closed in the Task Manager, only then can Firefox be restarted.

Does that also happen if you use File > Exit Firefox?
See also "Hang at exit":
* http://kb.mozillazine.org/Firefox_hangs
* [[Firefox hangs]]

Firefox.exe process remains after closing Firefox

I closed Firefox 5 over 45 minutes ago. At the time it closed, I had around 60 tabs open. The Firefox window closed, but now, over 30 minutes later, firefox.exe is still consuming 624 MB of memory. For the record, currently Windows Task Manager shows firefox.exe consuming 00 CPU, 639,772 K Mem Usage and a Peak Mem Usage of 771,296 K.
I'm seen this behavior at other times and, on those occasions, the firefox.exe process did eventually terminiate and release that memory. Why does firefox.exe take so long to terminate? Is this a bug or just a result of the way I use Firefox? I do tend to have a lot of tabs, 60 to 75, open at any given time. I'm guessing that's more tabs than the typical user.

I should go on to add that I have already seen the Firefox Hangs |Hang at exit document and none of these look like the obvious issue. I'm running Java Version 1.6.0_26, so current there. I'm not running any of the listed Internet security software. The only extensions I'm running are Java Console 6.0.26, ReloadEvery 5.0.0 and Xmarks 4.0.1, so not a lot of extensions.

BOMM - Metadata manager busobj.exe process limit number of report processed

Hello,
We're facing the following problem, we have a BOMM setup which is running flawless for universes and webi reports. But we have a huge amount (+8000) Deski reports all stored in the same folder.
While the integrator is processing the Deski reports at a certain point in time it goes wrong, we found out that to process the Deski reports BOMM launches a busobj.exe process which uses 2 GB of RAM at the moment the integrator stalls. The integrator does not give an out of memory error, it just stops processing and seems to timeout.
What I am now looking for is a parameter that can limit the number of Deski reports processed by the busobj.exe process, before it is terminated to free up the memory. We thought that the pplimit parameter would do just that, but it is not.
In the log we see all kinds of parameters, but there's very little information about what they do. These are arguments for which we would like to get some more information:
- maxSelect (defaults to 1000000)
- mtc
- ppc (number of concurrent jobs, but this seems not to influence the number of busobj sessions)
- pplimit
- ptc
our setup:
BOE = 3.1 SP2.5
BOMM Version: 12.1.0.6
Kind regards
Guy

Thank you Manoj,
This was already helpful, it confirmed our thoughts about the parameters.
I can not confirm your first comment about the fact that the busobj process closes after eacht report, I've monitored the processing on the server and during the run of the integrator the same busobj process was active (same PID).
Currently we try to process 100 reports at a time by manipulating the date modified on our dev enivronment by checking the reports in scope out and back in, and then starting the integrator.
The reports average around 200KB in size and none of them is set to refresh on open. Base on the logs it takes around 1 minute to process a single report. Depending on the fact if it is processing the associated universes or not. Disk space is not the issue.
I noticed similar behaviour when we used a VBA-script to feed our own mm, and I had to write code to limit the number of reports processed by the busobj process to around 100. I did this by closing the busobj process after 100 reports and then start a new batch of 100 reports in a new busobj process. I think busobj does not cleanup after closing the report, and with every report opened within the same process the memory usage of the process grows, until it reaches 1.8 GB and then the process just hangs.
I can open cases, if you can tell me on how to make sure it reaches you I'll just create one. Do you already have a release date for the fixpack you are talking about?
Regards
Guy

Acrobat.exe process not ending when application closes

This also affected the acrord32.exe process until I uninstalled adobe reader.
I have recently updated to the new 10.1.0 version of Acrobat (think I was running 10.0.1 before), I was not having the issue before upgrading.
I only discovered I had the problem because I tried to delete a PDF file I had just opened. I closed Acrobat, then tried to delete the field, yet it said it was in use. A check in task manager showed acrobat.exe still running. This is most annoying.
I'm running Windows 7 Professional x64 with SP1.
Note: This affected both the Adobe Reader as well as Acrobat X Pro, but doesn't seem to affect any other software.
Please advise of a fix for this, Thanks.

I have just completely removed Acrobat and reinstalled it having cleared all the folders that got left behind.
It installed ok, but now the 10.1 update wont install properly. It hangs at the "creating the adobe pdf printer" part. It eventually carrys on, but I end up with no Adobe PDF printer installed.

When exporting many videos with Lightroom 5, the process hangs randomly and needs to be restarted.

When exporting few videos, the process hangs randomly. The processor performance is 0 % and the lightroom says it is working (actually it is not). I have to quit lightroom, kill all processes like amecommand.exe, Adobe Media Core, Adobe Dynamic Link Manager and restart the process. It stops randomly.
I am exporting ALL-I videos from Canon 5D mark III, into H264, high quality.
PS: The same situation was with Lightroom 4.

Hello,
i have the same problem on LR5.5 on Win 7 (8G RAM)
Thank you for any help.

[Solved] Boot process hangs for installed Arch and installation usb

Hi. I've been using Arch Linux for around 6 months now and I'm in love with it. It is now my primary OS. However, I might have done something or performed some update, and I can no longer boot into Arch. The boot process hangs right before it should show the login screen (I'm using Gnome 3.6 with GDM). I see the following messages on the screen:
Loading Linux core repo kernel ...
Loading initial ramdisk ...
/dev/sda3: recovering journal
/dev/sda3: clean, 330610/1749664 files, 5585671/6996827 blocks
And then it hangs right there. I have to hard-reboot after this.
I then tried to boot using the Arch Linux Installation USB (archlinux-2012.12.01-dual.img), which also hangs at a particular point, before it should show me the prompt. I took a picture of the screen where it hangs: Screen Capture. This is an issue with just my laptop, because the USB boots just fine on another laptop I tried.
I also have Windows 7 and Ubuntu 12.10 installed on my system, and I'm able to boot into both of them.
I have 2 hard drives: /dev/sda is a 120GB SSD, and /dev/sdb is a 500GB hard disk. My partitions are as follows:

I tried adding nomodeset and acpi=off to the boot parameters, but the boot process still hangs. Please let me know if I should provide any other information.

Ok.. So my Arch Linux randomly decided to work. I'm sure I didn't do anything between my last "not working" state and my current "working" state. Below are a few things I tried:
I thought of trying an earlier build of ArchLinux, and downloaded archlinux-2012.11.01-dual.iso and made a bootable USB out of it. It still hung.
I was getting error messages during Arch boot that the last access time for the disks was at a future date. I found out that Ubuntu was using localtime instead of UTC and screwing up my hardware clock. I fixed it, and thought maybe the time issues were causing the boot problem. But fixing time didn't solve my problem.
I chrooted into Arch from my Ubuntu install, ran 'sudo pacman -Syyu' and updated my Arch install.
I thought maybe GDM isn't starting up. I re-enabled the service using 'systemctl enable gdm.service'.
I removed OpenNTPd and installed NTPd. Enabled the daemon using 'systemctl enable ntpd'
None of the above solved the problem, and rebooting to Arch still hung the system. So I stopped fiddling with it yesterday. Today, as usual, I just tried logging into Arch.. And it just worked out of the blue. The solution to me is as mysterious as the problem.
I told this to my friend who introduced me to Arch, and this is what he said:
Damn it computers, you were supposed to be deterministic!

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)].
