Is my OS infected ?

[Dark Star]

Hi All
I am using Gutsy Gibbon.. While surfing for a while my system hangs a lot .. The cursor didn't move and then I had to restart by abnormal shutdown. Whats the problem ? Is it a virus or what .. though its pretty obvious that its not a virus but I am facing the problem from quite a few days Please let me know the solution

Regards

[dsuresh]

not a virus .. did u create swap partition

[The_Devil_Himself]

^^I guess you can't install gutsy gibbon without creating swap partition.

U can try
* Updating
* Observe from Kde

As a second thought, how do u connect to net?

Check your hardware too. Most of such sudden problems are a result of failing or about to fail hardware.
Maybe you'll get some info in the logs too.

[NucleusKore]

During boot just see the messages, do you see fsck running often?

[Dark Star]

@mediator observe KDe ? WTH is this ? Its already updating..
@Mehul I guess this might be a problem !!!!
@NucleosKore No fsck didn't run often .Well I haven't seen it from a long time running during boot

Just FYI it only hangs if I use my PC for a long time and generally when I open pages heavy with Java and all plugins

Could well be cooling problems, Install some tempreture monitoring software and see if the tempreture is at normal level or not?

[sachin_kothari]

i faced a similar situation.
and that happened to me on ubuntu as well as vista (no probs in xp).
guess my hardware is not upto mark.

I've got a ditto issue while I run GNOME. It simply hangs, mostly while Firefox is open but happens otherwise too. The System simply stops responding, no HDD activity, no activity at all.

This however doesn't occur while I run KDE 3.5.x (kubuntu-desktop). And am on that now.

Plus, these hangs only sometimes respond to a ALT+SYSRQ+R|E|I|S|U|B keys. There's nothing in the logs about any sort of malfunctioning device, etc. I guess its some deep issue rooted under GNOME but I can't be sure.

You can avoid this issue by only using small load applications like rTorrent, MPD, etc. I've used them for long now and they hardly lead to such a situation. Can't replace Firefox, sadly. Addicted to that.

P.s. I thought this was due to my H/W (Even though Win-XP and Kubuntu work perfectly alright) but am glad am not alone

What version of gnome are you people using?

[FilledVoid]

Out of curiosity . Arent memory leaks supposed to create the same problems? I recall me getting pretty much the same issue when trackerd goes haywire. So you might want to check if that service is acting funky. Or check the memory consumption of other proceses.

Thanks Harsh your post made me feel gr88.. well in that case I will switch to KDE Also Gnome players stop responding but Amarok never hanged Here I comes KDE .. btw what do you guys suggest me KDE 3.5.8 or KDE 4.01 ?

[praka123]

for Me,in Gnome,no such problems apart from firefox hanging esp with java .yes,I am on Ubuntu with only 384MB of RAM and a 300MB swap

and..Debian Sid Gnome is tad faster than gutsy one.but now some people are saying gutsy sometimes is ....pita

I think ur problem may be buggy application(s) which uses out memory observe the common apps u use and monitor their memory usage via gnome-system-monitor .
if you found the faulty app,try submitting a bug report via reportbug script.

[vish786]

I am on gutsy gibbon gnome from past 2 days with 1024mb swap space... even if meh system hangs its just recovers back within few seconds :sigh:

There is no unkown app. I use Anjuta, Amarok ,FF, and nothing else. I don't know whats the problem .. Please tell me how to install KDE 3.5.8 in Ubuntu ? or should I install KDE 4.01 ?

Yes it seems like a bug to me. Also instead of firefox people can give a try to opera n then post.

[praka123]

^kde?sudo apt-get install kde4 ? or sudo apt-get install kubuntu-desktop ?

[FilledVoid]

To install KDE http://www.filledvoid.com/2008/02/15...ibbon-desktop/

I wrote the procedure for KDE 3.5 if you want 4.0.1 then theres a lin below at the bottom which points to the appropriate page which explains how to install that as well. However I think that you can have KDE 3.5 and 4.0.1 together or from what I read thats what I understand.

By the way I wouldn't try Opera on Ubuntu 64 bit or at least I experience the same problems you have in Firefox when I use Opera. However Firefox is working flawlessly for me. I think you need to monitor the memory being used . I suspect a memory leak in one of the applications you are using.

[QwertyManiac]

Dark_Star - List your hardware out please.

exx_2000 - Yes it might be possible due to some part of GNOME not keeping the memory leak in check, but sometimes (This thing is very random!) even applications like DrPython, etc lead to a crash.

Yes, trackerd explosion makes my HDD whine for some time but it recovers after the operation is complete (I disabled system CRON to avoid this from happening on a daily basis). This one is totally opposite.

I don't know how to report a bug this random, nor do I know how to look for one if already reported; just can't lock on to any descriptive keywords.

Ok I now doubt this is a processor issue, cause I have the same one (Prescott core but a generic PIV nevertheless).

na it even happens in windows,it prolly cos JRE takes some time to load and execute.and it isn't even hanging,it just freezing for a couple of seconds.

[praka123]

^ofcorz firefox+java sometimes hangs(Im using firefox3beta3).
I am not at all experiencing so called hangs !
My configuration:

P4 2.8 prescott(HT),384MB RAM,Nvidia 7300GT pci-e,gigabyte 915-GV based board,160+80GB hdd's .

Are u ppl saying Gnome lock up even in a clean Desktop?I think either some cron schedule will be running like updatedb or if beagled(too resource hungrY) runs in background this can happen.

@qwerty:I think you should start a thread in http://ubuntuforums.org

another option is are u ppl using 2.6.22-386 kernel?I am on Ubuntu on this kernel.may be try changing from kernel-generic to -386 kernel

[iMav]

well its not an infection my machine has a hung a lot of times like that it even froze during installations

True, Flash/Java tend to do this. I've experienced this in windows too.

Goto System > Prefs > Sessions > Uncheck Tracker and any instance of updatedb or beagle.

All the 386 kernels are not obsoleted. So its either generic or custom compiled kernel.
