Nmbd process using up 80+% of my CPU

Since upgrading to 10.5.5 my MacBook pro's fans have been going wild running at 5,000+ rpm. Looking in Activity monitor I see nmbd process hogging all my CPU. Can I safely kill this?
thanks.

Ok it started doing it again so the Samba install wasn't the real fix, must have just been lucky at the time.
I manually quit the process using Activity Monitor and immediately the fans slowed right down. But within about 1.5mins the process restarts automatically and the fans go full speed again.
This is really bugging me now, and killing my battery time when the fans are maxed out. Any more ideas?
Can I stop the service restarting? Do I need this service?

Why is the fontd process using up to 80% of CPU when I have InDesign CS6 open?

Macbook 13-inch, Aluminum, Late 2008
OS X 10.8.4
2.4 GHz Intel Core 2 Duo
This problem has arrisen within the past week and only happens when InDesign CS6 is open. I cleared the font cache last time and ran InDesign right after with no problem. Just started happening again. What gives?

Yeah, Font Book is how I've been importing many many different fonts I've been using in projects. I've skimmed the article you linked some more and it's great! I need to make the time to sit down and read it in depth to get it all down.
What's seemed to solve the probelm was repairing the disk and repairing permisions both a few times. That seemed to fix the issue entirely as there were some kinks in there that needed to be worked out from the recovery drive. Since then I haven't seen the fontd issue arrise again. If it does I'll post here. Thanks for your help!

How to kill Forms Runaway Process using 95% CPU and running for 2 hours.

We had a situation at E-Business Suite customer (using Oracle VM server) where some of Form processes were not being cleared by form timeout settings automatically.
Also when user exits the form session from front end, the linux form process (PID) and DB session did not exit properly, so they got hung.
They were spiking CPU and memory usage and causing e-business suite to perform slowely and ultimately causing VM host to reboot the production VM guest (running on Linux).
We could see the form processes (PIDs) using almost 100% cpu with "top" command and running for a long time.
Also we verified those Form Sessions did not exist in the application itself.
ie. Using from Grid Control -> OAM-> Site Map -> Monitoring (tab) -> "Form Sessions".
It means that we could safely kill that form process from Linux using "kill -9 <PID>" command.
But that required a continuous monitoring and manual DBA intervention as customer is 24x7 customer.
So, I wrote a shell script to do the following;
• Cron job runs every half an hour 7 days a week which calls this shell script.
• Shell script runs and tries to find "top two" f60webmx processes (form sessions) using over 95% cpu with 2 minutes interval.
• If no process is found or CPU% is less than 95%, it exits and does nothing.
• If top process is found, it searches for its DB session using apps login (with hidden apps password file - /home/applmgr/.pwd).
a. If DB session is NOT found (which means form process is hung), it kills the process from unix and emails results to <[email protected]>
b. If DB session is found, it waits for 2 hours so that form process times automatically via form session timeout setting.
It also emails the SQL to check the DB session for that form process.
c. If DB session is found and it does not timeout after 2 hours,
it kills the process from unix (which in turn kills the DB session). Output is emailed.
This are the files required for this;
1. Cron job which calls the shell script looks like this;
# Kill form runaway process, using over 95% cpu having no DB session or DB session for > 2hrs
00,30 * * * * /home/applmgr/forms_runaway.sh 2>&1
2. SQL that this script calls is /home/applmgr/frm_runaway.sql and looks like;
set head off
set verify off
set feedback off
set pagesize 0
define form_client_PID = &1
select count(*) from v$session s , v$process p, FND_FORM_SESSIONS_V f where S.AUDSID=f.audsid and p.addr=s.paddr and s.process='&form_client_PID';
3. Actual shell script is /home/applmgr/forms_runaway.sh and looks like;

If you have the same problem with some other unix and DB processes, the script can be easily modified and used.
But use this with thorough testing first (by commenting out <kill -9 $PID1> lines.
Good luck.

Solaris 9: Xsun process using over 47% of CPU

Anyone else having this problem?
The /usr/openwin/bin/Xsun process is consistently using over 47% of the CPU
on a Sun Fire V240 running Solaris 9. This system was just built last week
with all recommended patches. In the past 24 hours it has accumulated 1341:35
of execution time according to ps. It is now up to 1350:08 in the time it took me
to finish this message.

I had a similar problem with my v240 with my XVR-100 frame buffer, and was told that there is an incident that is not closed in a security patch for this, and that the work around was as follows:
mkdir /etc/dt/config
cp /usr/dt/config/Xconfig /etc/dt/config
cp /usr/dt/config/Xsetup /etc/dt/config
add "/usr/openwin/bin/xset -fbpm" to the end of /etc/dt/config/Xsetup
edit /etc/dt/config/Xconfig and change
Dtlogin*setup: Xsetup
to
Dtlogin*setup: /etc/dt/config/Xsetup

Sockd process uses a lot of CPU time

Hi,
I'm running the Sun Java System Web Proxy Server version 4.02 on a SunFire V210 dual processor box running Solaris 10 with the default socks5.conf for testing.
Just browsing a few web pages in Firefox or IE using the socks proxy boosts CPU usage from the sockd process to a staggering 50% and stay there for several minutes.
Comparing with the old NEC reference Socks5 daemon the Sun version is really performing badly.
The system is pretty standard though I have tuned /etc/system and the tcp stack using recommendations in the proxy administration manual. All Solaris 10 patches are installed.
prstat output:
   PID USERNAME SIZE   RSS STATE PRI NICE      TIME CPU PROCESS/NLWP
24519 proxy    6664K 4384K cpu1     0   10   0:11:18 50% sockd/43Any ideas what's wrong or do I have to stick with the old NEC reference daemon?

After closing Firefox to use IE8 or any other program (like InterVideo to watch a DVD), everything is very choppy and slow. I have to go into Taskbar, Processes, and close firefox.exe manually (which is using up all the memory/CPU and should have closed before). Then, and only then, does everything behave normally. What is going on and what am I doing wrong or missing??
== This happened ==
Every time Firefox opened
== about a couple months ago and happens every time I close Firefox.

'''Safe Mode'''
You may need to use '''[[Safe Mode]]''' (click on "Safe Mode" and read) to localize the problem. Firefox SafeMode is a diagnostic mode that disables extensions and some other features of Firefox. If you are using a theme, switch to the DEFAULT theme: Tools > Add-ons > Themes before starting Safe Mode. When entering Safe Mode, do not check any items on the entry window, just click "Continue in Safe Mode". Test to see if the problem you are experiencing is corrected.
See:
'''[[Troubleshooting extensions and themes]]'''

'''[[Basic Troubleshooting]]'''
If the problem does not occur in Safe-mode then disable all of your extensions and then try to find which is causing it by enabling one at a time until the problem reappears. You have to close and restart Firefox after each change via File > Restart Firefox (on Mac: Firefox > Quit). You can use "Disable all add-ons" on the Safe mode start window.

Syslogd process uses all available cpu & console app won't run.

I have a Mac Mini (G4 power PC) running 10.5.5. Just recently after several minutes the system never wakes. It just shows the SBBOD. All I can do is hold down the power button and reboot. When the system reboots, using the activity monitor, I see that the process named syslogd uses all available cpu. I can still do things, but the cpu is saturated.
I took a snapshot of the syslogd process, and I can post it here if anyone thinks it might help.
If I activate the console application, the window comes up then hangs with the SBBOD.
The syslogd process uses all available cpu right after reboot, and does so regardless of which user (including root) is logged in. Attempting to kill the syslogd process with the activity monitor does nothing

Thanks! It took a long time for the disk utility to fix the permissions, but as soon as it did, the logger process calmed down. Looking at the log file now, I see it was my McAfee virus scan causing the logger to flip-out.
I'm now looking for a new MAC anti-virus program.

"airport" process uses all of the memory an cpu

After I reinstalled my MacBook and updated to the latest version of Tiger (10.4.8) my airport network behaves very strange. When I boot my MacBook or disconnect/connect my Airport network a process called "airport" is consuming all the CPU and memory. It uses one core exclusivly and gows to 1,2 GByte of RAM (even more virtual Memory). This slows down the macbook to almost still and heats up the CPU.
The only thing I can do is to kill the process. Then everything works fine. But this is annoying.
It seems to make no difference if I use a wireless LAN or not. When airport is enabled then this bug occurs.

On this thread,
http://discussions.apple.com/thread.jspa?messageID=349
2852, people that have Check Point Software's
SecureClient are reporting the airport process using
~95% of CPU time.
I had SecureClient installed and I can confirm that
if you uninstall SecureClient, the airport process
works normally again. I don't know if this is the
only source of this problem, but if you happen to
have SecureClient, then you might want to uninstall
and confirm if this solves your problem.
Also I would be curious if anyone is having this
problem that has never had SecureClient, or any 3rd
party VPN software.
I can confirm that at least some of my problem with the "airport" process was related to VPN software. After uninstalling the Cisco VPN client, problems dramatically reduced. Interestingly, I still have the Checkpoint client installed, but only rarely see problems with "airport".

What is mdworker and why is using so much of my CPU?

I've read earlier threads in which mdworker is mentioned or discussed but have not found an answer for my question. Actually, one post came close, but it was from a few years ago, and mentioned a tab on Activity Monitor that does not exist on copy.
So, the issue is that periodically my fan starts racing. I'm used to that happening when Time Machine is doing its backups, but recently I've noticed that it's happening even though Time Machine is not running. When I go to the Activity Monitor I see that mdworker is using a very high percentage of my CPU's capacity, way more than any other process.
I gather from scanning posts on earlier threads that mdworker is used by other processes, and that the problem may lie there. But I don't know how to identify the other processes or what to do when I find them.
Help appreciated.
Thanks,
Eric Weir

FAILURE: 21:17:15: Error when retrieving tags from path /Users/ericweir/Library/Mail/Mailboxes/1 priority/2 news.mbox/Messages/308064.emlx: Error Domain=NSPOSIXErrorDomain Code=2 UserInfo=0x10018d5e0 "The operation couldn’t be completed. No such file or directory" (mdworker)
And this:

10:34:22: Spotlight plugin registered!

FAILURE: 10:34:22: The spotlight attribute kMDItemOMUserTagTime is not registered
10:34:23: Tag Query kMDItemOMUserTags == '*' executed
Tags is a tagging utility I checked out a couple months or so back that I decided not to use. I'm assuming the records in this log have reference to it. I still have the app installed. Might getting rid of it resolve the problem?

System using a big percentage of CPU

My mac is very slow. I launched safari but the system is using more tham 60% percent of CPU, while the user it shows using 30%.
How can I make it get better and faster? I have already cleaned safari cache and history. What I have to do to get down this system CPU usage?

I suggest you open Activity Monitor (it is in /Applications/Utilities) and try to find what processes are using so much of the CPU.
You are not giving us enough information as it is. Report what you get from Activity Monitor, and also what model is your mac, how much ram, what os...

Process Using too much Processor

Hi all !
I have a real wierd request.
I have a process which runs for about a hour converting files. The process only between 10 and 15MB of memory which is fine. The problem is that the process uses basically all the processing power available on the server. My administrator is worried that if another process is started whie mine is running it will not receive a share of the processor . Even though I have told him (and showed him) that the java app releases some of the processor when another program requests it.
Is there anyway of specifying the percentage of processor a java app uses ? For example I would like to tell the app to only use 50% of the available processor !
Robin

How computationally intensive is the conversion? Are they small files that require sophisticated processing? Or are they large files that are processed in a simple way?
I'm asking because it's very unusual for a process that does significant I/O to peg the CPU. The fact that it does may point to a bug in the code.

How to find memory taken by a process using top command

I wanted to know how to find the memory taken by a process using top command. The output of the top command is as follows as an example:
Mem: 13333364k total, 13238904k used, 94460k free, 623640k buffers
Swap: 25165816k total, 112k used, 25165704k free, 4572904k cached

I hope, my question is clear as to how to find the memory taken by a process using top command.
Please revert with the reply to my query.

Have you tried "man top" to see the documentation for the top command?
How about the following: http://lmgtfy.com/?q=show+memory+with+top+command
The 5th column (VIRT) shows the amount of RAM + swap
The 6th column (RES) shows RAM
The 7th column (SHR) shows memory shared between processes

How to find memory taken by Oracle processes using top command

I wanted to know how to find the memory taken by Oracle processes using top command. The output of the top command is as follows as an example:

The different Oracle processes could be Oracle database, Oracle listener, Oracle enterprise manager etc.
I hope, my question is clear as to how to find the memory taken by a process using top command.
Please revert with the reply to my query.

a short and correct answer would be: you can't.
As oracle uses a fair amount of shared memory, and that shared memory is attached to most of the oracle processes, the same memory appears a number of times.
you should rephrase your question / what is it you want to achieve?
you can ask oracle how much memory is assigned to it, v$sga, v$sgastat, v$process (for PGA). moreover, you as DBA are the one who configured that.
you can look at major an minor faults per process to see what is causing the paging (if you have any).
you can also look at the /proc/pid/statm pseudofilesystem for your oracle pids.

"Report Crash" Using Over 80% of my CPU

My Macbook pro 2013 have been recently getting slower over time and now it has gotten really bad...
I've looked into it some and i have found out that in Activity Monitor this process called "Report Crash" is using over 80% of my cpu, and i have tried to quit the process but it just comes right back with in a matter of seconds.
Any ideas on how to fix this?
Specs on my macbook-
2013 model
4gb of ram
Intel core i5 2.5 Ghz
250gb hard drive
No ssd
Os-
OSX 10.8.5
Thanks in advance,
Thomas

When you have the problem, note the exact time: hour, minute, second.
If you have more than one user account, these instructions must be carried out as an administrator.

Mds and mdworker are constantly using 10%-40% of my CPU since partitioning.

2 days ago I partitioned approximately 80GB of my 500GB 7200rpm macbook pro drive to be used for Windows 7. There was 430GB of free space on my HDD at the time so I know that there was no overwrite issue. It has successfully been installed and runs very well. However, since I did this the mds and mdsworker processes on the Mac side are constantly using large amounts of my CPU and are bogging down my computer. I understand that these services help create the Spotlight database. Is anyone aware of this issue?

After two days I'd say it's time to start over. Go to the System Preferences application- you can get to it by clicking on the Apple in the upper right corner, System Preferences is about a third of the way down the menu. When it's open, select Spotlight from the list of preferences. Under "Search Results" in Spotlight you will see the order in which results will be displayed. If you want to change the order, now would be a good time.
Uncheck all the boxes, this will remove them from the consideration of Spotlight. Then re-check the ones you wish to be available in Spotlight, this will force them to be re-indexed. My arithmetic says your files should occupy not much more than 50 GB, this should not take long to index.
You could try just Applications, or just System Preferences first to see if it is able to complete the task. If it takes longer than a few minutes, there's likely something else going on, perhaps related to your partitioning.
Good luck! Joel.
