I installed ubuntu 10.10 a few days ago which ran very well on the live CD but after I upgraded to 11.04 Ubuntu uses just under 100% of my cpu after a few mins loged in and my ram usage increases by about 5MB per sec starting the second I log in. I am using Classic Gnome and it seems to do this wether I have metacity or compiz turned on. Does anyone know what is going on or know about a way to lower ether my cpu or ram usage

During random moments, pidgin will suddenly use up all of my processor, a large chunk of my ram (20% - 25% of 2 GB), and will become completely unresponsive. This lasts for maybe four or five minutes then returns to normal.Pidgin doesn't have any kind of terminal output when ran in a terminal, so I have no data to use that is of any help.

Does anyone else have an issue with Firefox memory hogging? If you open many tabs, it just seems to use up most of the memory and despite closing a tab it will not release it.You have to restart the browser every so often.
View 3 Replies View RelatedI am running a fairly standard 32bit 10.10 install, although I deleted Firefox and installed Chrome. I am using Transmission for my torrent downloads. After a lot of reading and trying different things, I have managed to get the port to open. When Transmission is running, even if only uploading and downloading a few k each way, I have great difficulty in getting Chrome to load a web page, it is as if Transmission is hogging all the available bandwidth? Obviously if I shut down Transmission the problem goes away. It also occurred with Firefox before I deleted it.
View 6 Replies View RelatedRecently I have noticed that the process kacpi_notify is using constantly using 10-14% of my total CPU time, I am running an i7 @ 2.66Ghz. This causes the CPU temp to rise, and eventually the fan will kick in to cool it down, at which point kacpi_notify will stop using CPU time. Then about a minute later it will kick in again and use CPU time up constantly until the fan kicks in because of it. It sounds like something is triggering the process and then it is stuck in an endless loop. I just don't know where I can modify this so it doesn't start up all the time.Some tech stuff:
Kernel: 2.6.34.7
OS: Opensuse 11.3

I did my homework and found those similar questions, but they seem to cover particular firefox addons. My scenario is different: I don't run a ton of addons, but still periodically CPU usage skyrockets to 100% (I have an old single core CPU). I wonder if it is possible to see which tab is the offending one. Generally I don't run a gazillion of tabs, I try to stick to the 7+/-2 common sense rule, but closing tabs one by one and watching the CPU usage is still not very convenient.
View 2 Replies View RelatedAll of a sudden, my computer feels sluggish. Mouse moves but windows take ages to open, etc. uptime says the load is 7.69 and raising. What is the fastest way to find out which process(es) are the cause of the load? Now, "top" and similar tools isn't the answer because they either show CPU or memory usage but not both at the same time. What I need is the single command which I might be able to type as it happens - something that will figure out any of: "System is trying to swap 8GB of RAM to disk because process X ..." or "process X seeks all over the disk" or "process X uses 400% CPU"
So what I'm looking for is iostat, htop/atop and similar tools run into one with an output like this:
1235 cp - Disk trashing
87 chrome - Uses 2GB of RAM
137 nfs_bench - Uses 95% of the network bandwidth
I don't want a tool that gives me some numbers which I can analyze but a tool that tells me exactly which process causes the current load. Assume that the user in front of the keyboard barely knows how to write "process" but is quickly overwhelmed when it comes to "resident size", "virtual memory" or "process life cycle".
My argument goes like this: User notices problem. There can be thousands of reasons ... well, almost. User wants to know source of problem. The current solutions give me lots of numbers and I need to know what these numbers mean. What I'm looking for is a meta tool. 99% of the data is irrelevant to the problem. So what the tool should do is look for processes which hog some resource and list only those along with "this process needs a lot of CPU, this produces many IRQs, this process allocates a lot of RAM (and it's still growing)".
This will be a relatively short list. It will be much more simple for an newbie to locate the culprit from this list than from the output of, say, htop which gives me about 5000 numbers but requires me to fold multi-threaded processes myself (I have 50 lines which say VIRT 2750M but only 16GB of RAM - the machine ought to swap itself to death but of course, this is a misinterpretation of the data that can happen quickly).
I just bought an SSL cert and installed on my Apache server. When I restarted something went wrong so I had to change some config stuff and when I tried to restart apache for the second time I got this:
$ sudo apache2ctl start
(98)Address already in use: make_sock: could not bind to address [::]:80
(98)Address already in use: make_sock: could not bind to address 0.0.0.0:80
no listening sockets available, shutting down
Unable to open logs
Problem is that apache isn't running. For some reason there is something hogging my tcp 80 port, preventing apache from starting properly. How do I fix this? Is there a way to "free" a port?
I am running Fedora 9 and KDE 4.2.1. I want to set up some traffic shaping on my machine to prevent my torrent client from hogging my entire bandwidth. I.e., I want KTorrent to download and upload to the best of its ability, but still be able to browse the net freely in spite of the torrents. I have done some reading about traffic shaping in Linux. There is lots of material about it, but most of it (such as the lartc.org "howto") is very complex and comprehensive and looks extremely intimidating. Furthermore, most of it addresses situations where you want to distribute traffic between multiple computers in a network. I just want to manage processes on a single machine. I am hoping for a piece of software that lets me assign each a "priority" to each application, or something like that. Like cFosSpeed for Windows.

I got a fairly powerful media system standing in the living room. Most of the time it is idle, maybe playing some music. At the same time I got a pc in my office that is less resourceful. Sometimes I'll run programs through ssh with the -XC command. This way a program will seemingly run on my office pc, while it is actually running on the media system. However:
- 1 Sound doesn't transfer to the office pc.
- 2 When using a program I need to constantly be aware where I save my files. Sometimes it is located on the remote computer, sometimes it isn't.
Is there an alternative way to use the resources on the media system? E.g. run a program that is stored on the office pc and process it on the media system?
Both systems run Ubuntu (office 10.04 - media system 10.10).
I just recently upgraded to 10.04 (LTS), and I have been using stardict app for a long time with nothing but success on each of my laptops anc omputers I have had over the past 5 or so years. However, now on one laptop after starting the stardict app, using panel the applet I create on my xfce4-panel (as per normal), and looking up a word (highlight and press shift key which i use for quick word search using stardict), the app begins using 100% cpu resources and I am forced to kill the process.
The problem is intermittent, meaning it only occurs half of the time I am using startdict, while the other half of the time it operates normally. I have been trying to see if there is some sort of pattern, perhaps other apps running at the time the problem occurs, but I have not noticed anything that looks suspect, since I generally fire up stardict after boot in and have had it happen (the problem) without even any other apps open (just testing to try and find some sort of pattern to locate the potential issue).
I use a standard set of dictionary files for each of my comps, and currently have stardict operating fine on 2 other laptops, both running 10.04, with the same set-up (xubu, same apps, and settings pretty much) and no indications of this problem on either (other) laptop.

I just wondering what is the difference between RES, SHR, and VIRT.
1) The VIRT always seems to be higher. Is this using the paging file system. (virtual memory on the harddisk, the swap memory)
2) Is the RES memory the actual physical RAM memory?
3) Is shared memory sharing memory with other processes?
4) Just a final question. As I am running on a HP Mini 210, memory and CPU is a resource I don't have a abundence of. So if was to compare for example 2 difference browsers i.e. firefox and midora. What should I brench mark between to 2 to find what one uses less resources?
I am going to write two or more programs that will take control of the same resources on Linux. What are the common methods/functions that can do locks/synchronizations in C?
