Memory leak , some process eating my all memory.

[sukhdeepsingh]

Hola,

I have had a fresh install of Ubuntu 9.10 and installed some software after that.
Since third some, some process is eating half of my memory.
I have checked processes running in system manager but everything is normal.
Maximum is consumed by compiz which is about 26 mb, seems very normal.

I did restarted my computer several times, and in the start for 5 mins, its fine after that again my cpu fans runs at very fast speed and my one cpu is used up 95 % (I have dual core).
Please help me out, this invisible thing is driving me crazy.

I am attaching my htop screen shot (sorted by cpu %), now the cpu is not used by completely but fan is still struggling hard and fast.

Hi gufide,
Thats what i am saying. but fan is running harder than normal work.

I will post another htop, when the system is occupied again with that invisible process.

Thanks

Hi no2498 and gufide,
I am attaching new htop and free -m results.
I have figured it out, there's a process called snort, but i dont know why its running and using 100% of my 1 cpu.

             total       used       free     shared    buffers     cached
Mem:          2003       1419        584          0        113        868

if its snort, then what is it associated with and how to kill it without further harm.
Cheers

This is snort:
http://www.snort.org/

It should not be installed by default, its a network sniffer.
To get rid of it, kill it first

sudo killall snort

then uninstall it

sudo apt-get remove snort

Thanks mate,
I think it was there, because I was using vpn,
so does it mean , after un installing it, I wll not be able to use my vpn.

Thanks

Your mem seemed fine. This output says that you were only using 437mb.

-/+ buffers/cache:        437       1566

SHouldnt interfere with the VPN. But if you run the uninstall command, you will get a rather verbose output of snort's dependencies, that is the other packages that will be removed (because they depend on snort). I highly doubt that will include any VPN stuff, but see for yourself. You can always abort the uninstall if for some reason apt-get does want to remove your VPN stuff (in which case, please copy paste the output here).

A leak would show increasing memory use, you should just keep on eye on for awhile.
In the sysstat package is pidstat, you could use that.
Ex.

pidstat -r -p XXXX 60 100 >> mem.log

Replace red with the process id, blue with time between reports in sec's, # of reports respectively. just minimize the terminal, report in home folder
This may show id if you don't happen to see in htop
ps -A |grep snort
