CPUs at 100% - Cause is two unknown tcsh processes

Every once in a while, I've noticed both CPUs' usage pegging at 100%. Each time, checking Activity Monitor shows two tcsh processes hogging the CPU. This is happening although I have started no terminal session, therefore no tcsh processes of my own. Force quitting these processes is not causing any obvious negative results, and is reducing my CPU usages to normal.
Does anyone know if the system itself is starting these processes for some worthwhile purpose? Or any other cause?

Hi AndyK,
When the cpu's are running flat out next time, try to enter this into the Terminal:
<pre>ps -auxwww | grep tcsh</pre>
That should list the active tsch processes and give a bit more information about what they are doing.

What is causing the two step save process in Acrobat XI?

Acrobat Reader XI will not save a pdf back to the same file name on the first try. It changes the name to A9R9FF*.tmp (the * being a wildcard) and gives the error message can not save rename file. When I then choose the original file it saves it over the original. Adds an extra step to the save function. What is causing this. It did not occur in previous versions of Acrobat Reader.

Hey mwhessel,
Please clarify whether you are using Adobe Reader or Acrobat.
Does this happen with every PDF you try to save or any specific one?
Try saving the file to another privileged location and check if you face the same issue.
Please let me know.

I can't login caused of an unknown error (-9808)

I can't login caused of an unknown error (-9808) since a few weeks. I know my Apple ID and the right password...
I also can't create a new account, but the connenction to the internet is there and I can also use the itunes store with all functionalities exept the log in...
All the other desciptions of this error (-9808) and sugestions don't work. I've also got the latest version of itunes.

I've seen this before but I'm a bit unsure of these kind of things. Is it really trustworthy? But thanks anyway for the answer, I'll probably try it anyway.

I have an IPad2. I've received two different ideas on charging the battery. One person indicates I should let the battery run almost down before recharging; another person indicated I should keep it charged closer to 100% . What is the best process?

I have an IPad2. I've received two different ideas on charging the battery. One person indicates I should let the battery run almost down before recharging; another person indicated I should keep it charged closer to 100% . What is the best process for the best battery life over time?

I do exactly as Thomas Reed does. Always have from day one. Going on 15 months now and I get at least 10 hours of use out the battery every day. No matter how much juice is left on the device when I go to bed - I put the iPad on the charger - doesn't matter what the battery gauge says - I plug it in and let it charge all night.

Two nalagent.exe processes w/ 100% cpu on App Launcher close

Hello. We are wondering if nalagent.exe is supposed to be running twice as it does not appear to be this way on all workstations. One nalagent.exe process is running under NT AUTHORITY\SYSTEM, and the other nalagent.exe process is running under the username.
Reason we are asking is because the one running under the username consumes 100% cpu immediately after closing the Application Launcher Window running on the desktop. Upon closing the Application Launcher, the AUTHORITY\SYSTEM nalagent.exe process closes, and the user nalagent.exe process remains and instantly spikes to 100% indefinitely (unless you kill the process in the task manager).
Using Sysinternals Process Monitor reveals that nalagent.exe is constantly scanning for the following nonexistent registry key: [HKEY_CURRENT_USER\Software\NetWare\NAL\1.0\Process Management]. These registry lookups appear to be what is causing the 100% cpu usage, but why? Creating the Process Management key does not eliminate the lookups.
This issue is possibly related to another 100% cpu bug we experienced with a "save icons" feature being stored under the [HKEY_CURRENT_USER\Software\NetWare\NAL\1.0\Links] registry key. We followed the suggestion of deleting the Links key on logon in the following post and this seems to prevent nalagent.exe from automatically starting up at 100% cpu. Our current issue is only when closing the Application Launcher which starts the 100% cpu usage.

We have considered preventing the Application Launcher from being closed but there appears to be an underlying problem we would like to understand further. Thank you for any information.

Lion update causes Safari two "quit unexpectedly"

Most recent Lion update causes Safari two "quit unexpectedly" on 2 of my iMac's and my Macbook. Has anyone else had the same problem, and/or can anyone help with this? Firefox is working fine.
Tracy

My Safari had the same issue last week "quit unexpectedly" right after it started.
Any way, this linked helped me

It's apple's link to Safari 6.

I can't access the app store - I get the following messages - error 1004 or 100 or 4 or unknown error - help!!!

I can't access the app store - I get the following messages - error 1004 or 100 or 4 or unknown error - help!!!
I've disabled the firewalls, the virus protection, the application protection - nothing helps.

I'd maybe try doing a search for Safari on your iPad first (swipe to the left to search). If it shows up in that search you can go to Settings > General > Reset and choose 'reset home screen layout' which will put it back where it would be by default.
All else fails? Restore it.

Two java.exe processes running in the Task Manager in Windows XP

I tried to find the best possible place to post this and after spending about 20 minutes searching for an appropriate forum starting from java.com I ended up here. So forgive me if the is a wrong place and if there?s a more appropriate place for my question, please provide a pointer to it.
I don't know much about java and what it does but as the title says when I open the Task manager there are two java.exe processes running at the same time with about 20 000 k each.
One of the processes is coming from:
C:\Program Files\Alias\Maya6.5\docs\jre\bin\java.exe
and the other from:
C:\Program Files\Alias\Maya7.0\docs\jre\bin\java.exe
in addition to that a jusched.exe process is also running coming from
C:\Program Files\Java\jre1.5.0_10\bin\jusched.exe
I rarely open the Maya 6.5 and 7 documentations but the two java.exe process are running all the time and I would like to stop them running when I don?t need them but I don?t know how.
I can't end these processes from the Task Manager; they reappear immediately after I end them.
Any help with this is greatly appreciated.
Thank you

Browser freezes during page loading and then either shows the cause as silverlight, or flash to be the cause, on two different computers, since last 3 upgrades

Since the last three upgrades of Firefox the browser starts to load a web page then freezes. A pop up states that either silverlight or flash have stopped working. This can last for as long as two minutes before it continues to load, or for as little as five seconds.
I have tried various methods to cure this, by reinstalling silverlight, flash, and Firefox.
The only permanent cure is to revert back to an older version of Firefox. I would continue with an earlier version but I get sick and tired of popups from the likes of Yahoo, and yourself telling me to upgrade.
I have also put the the program back to basics, and this is a pain because when I find it's still the same I have to reload all the add ons. Maybe you could devise a method where we only need to click a button to put everything back as it was before resetting it to default.
This problem is occurring on two totally different computers, both running Intel gear, one i7 at 3.5, with 8 meg of ram, one core 2 duo with 4meg of ram, no drain from graphics cards as they all have their own ram.
i7 desktop Windows 7 Ultimate 64bit, and Dell XPS Laptop core 2 duo Windows 7 Ultimate 32bit both latest windows 7 versions

Two unknown computers show up under "shared." What does this mean?

When I open a finder window, two computers that are unknown to me show up under "shared." What does this mean?
Does this mean someone has broken into my wireless network? Or that these people have access to my files? I don't want to be "sharing" anything with people I don't even know.

It means two of your neighbors also have a wireless network. They cannot access your computer unless you give them your userid and password.
Go ahead and try to access their computers. Unless they have guest sharing turned on, usually to share photos with family and friends, you will not be able to access their computers.
I’m on a university network and have hundreds of names in the Shared section of my sidebar, but do not have access to their computers, nor theirs to mine.

I can't remove two unknown saved passwords on Safari...

Hello Apple Community,
I found today two passwords from unknown sites. I'm trying to delete them but nothing has happened. I have already erased all my other saved passwords, website data, history, cookies, and restarted the computer/iphone, buy the passwords are still there. And, to be clear, I have nothing to do with those emails.
I will appreciate any help.
Thank you very much

Not sure why you are concerned about passwords at this point if you are selling the laptop.
Just erase the hard drive. None of your personal information will be retained on the drive.

Wired memory counts up to 100%, how to find unknown process leaking memory

Hi,
On my Macbook Pro 2011, 8GB wired memory counts up to 100% over a period of 4-5 regular usage days. The more I use the macbook, the more wired memory grows until I have to restart again, otherwise the machine becomes slow because it uses the harddrive for memory. This is not normal behavior!
Attached is a screenshot of the activity monitor. I'm not able to identify the process which leaks the wired memory.
I had once an eyeopening experience: I was about to restart my macbook totally overloaded by wired memory but then I canceled the shutdown because of some reason. Some of the processes and programmes were already terminated and SURPRISE, the wired memory was down to 10%! The 8 Gb were all of a sudden shared by free, active and inactive memory, as it should be! So some process was terminated during shutdown which caused the leak and even freed all of the wired memory. I did work with the macbook for 2 more days without any memory problem. Once I restarted, the leaking problem started again.
My gut-feeling says the hole problem started when I installed VM Ware Fusion a while ago. But I did a clean uninstall.
The solution could be to identify the leaking process, but how should I do this? It is also not clear to me wether wired memory is real, virtual, private or shared memory displayed in the activity monitor. Is there any tool which identify memory leaks?
According to g_wolfman, the only process with a hugh difference between real and virtual memory is the kernel_task and the many Chrome Renderer processes. I have always 30 tabs open in chrome plus Safari (Flash disabled). I'm not able to terminate the kernel_task of course.
Is there any way to isolate the troublesome process? There is no save start mode like in Microsoft Windows possible? This would be the first think I would do, checking if the problem persists in save mode.
Disabled every start login objects btw.
See in the image the amount of wired memory compared to the processes which are active. This is NOT the smart memory management OSX is capable of.

Any suggestion? Is my system doomed to bleed to death every 3-4 days, until memory went 100% red (wired)? I would expect OS X to be smart enough to indicate memory leakers. I really do not get it.
I migrated the same settings and applications to my freshly installed (10.7.4) 2007 Macbook. There the majority of RAM is active not wired.
The only big difference is: On my 2011 Macbook Pro was VMWARE Fusion installed.

Printing a PDF file online with any OJ 100 printer,we receive unknown error light sequence.

When printing a PDF file online on all of our Officejet 100 Mobile L411 USB printers, we encounter an undocumented error light sequence. The error light sequence we encounter is Power light blinks in conjuction with the Bluetooth light then those 2 lights blink off and the Resume light and both cartridge lights blink on. then those three lights blink off and the power light and the Bluetooth light blink on again and so it goes. You cannot reset this error by any other means other than powering the printer down and the printer will not power down with the power button. The only way the printer will power down with the above flashing light sequence showing is to disconnect AC power and remove the battery.
With the above described flashing light sequence displayed, the printer has no problem continuing to print and will continue to print other documents with the flashing light seguence displayed.
If the above mentioned PDF file is saved off to the computer and then printed from there, it will print on this printer ok without starting the flashing light sequence described above so evidently there are control characters attached to the online PDF file that get stripped off when the document is saved. I don't know what those characters could be but I do know that only all of the Officejet 100 printers we have display this problem. We can print the same documents on our HP 470 mobile printers ok without any issues or have no problem printing the same document with other models of HP printers. It is only when printing this document with any HP Officejet 100 mobile L411 printer that we have this problem.
As mentioned above, the flashing light sequence described above is not a sequence described in the Operators Manual so we don't know what it means. Also it is apparent that the online document(s) we are printing have some control characters attached to them that are incompatible with this printer but we do not know what characters they are. Are there some settings that we can setup in the printers properties that would solve this issue for us?
As I have explained above, this particular flashing light seguence does not keep the printer from printing the online documents or any other documents succesfully, however this sequence cannot be reset by any other way other than killing all power to the printer.

Hi Bailie,
You might try looking for a paper jam or carriage jam.
