CPU usage

yberf 06 Jan 2011 21:01

Hi all,
since a couple of days my WhiteLight runs really slow; I supposed the problem was the network but testing the WiFi net and the root I haven't found any problem. I've checked the system performance and discovered that the CPU is abnormally used:

Sys Up Time : 21:58:03 up 50 min load average: 6.55 
Temperature : 45 ° Celsius
Total Memory : 126828 kB 
Free Memory : 37116 kB 
CPU Load during last Minute: 6.66 
CPU Load during last 5 Minutes: 6.86 
CPU Load during last 15 Minutes: 
Performance History : 
45, 126828 kB, 37656 kB, 6.67, 6.87,
45, 126828 kB, 37116 kB, 6.66, 6.86,

I suppose there's a process that is using (I don't know why!!) too much the system but I'm not able to understand which could be. Could someone help me please?

Please use command :

top

It will show you which process eats CPU & ram.

no idea about cvm, but if you don't use Mionet and twonky you can disable them from running and save some CPU power that way.
In my WhiteLight I also disabled /usr/bin/mDNSResponder -f /etc/mDNSResponder.conf

p.s. Is this really WhiteLight edition of MyBook? Looks like Blue ring..

I've already tryed to disable both Twonky and MioNet but the problem remains;
It's really a WhiteLight, I confirm, and probably the strange processes you noticed are also the reason of the missfunction I'm arguing about. I'm going to try to update the firmware to the new version and in case it will not work anyhow, I'll reset everything to factory default.
thanks for your hints :)

Hi yberf

What strange processes?

cvm?

I am not in front of my mbwe but I think cvm is part of mionet….cant remember, but go into /etc/init.d and do the following:

grep cvm *

this will pull all the files with cvm in them and tell you the file…I think it is mionet but this will tell you.

The reason there are so many processes-and this is where I am rusty—is that these are streams…sort of not one process but mulitple under one so they can work with multiple request…sorry have not really explained that very well. The interesting thing is that is taking up 10% of your memory. I believe this is how mine is set up also when running normally.

My issue is only when I run iTunes on my pc where I have placed my library on the MBWE (not the shared library) and use the mapped drive to pull the data.

Looking at your ps and top command I am not sure that this is unusual. Have you tried a reboot.

Also if you have stopped twonky and mionet, do you still see cvm process?

Cheers

G

the cvm process were in sleeping mode, did not use much cpu but a lot of memory was reserved for them, they were propagated by process 5397. From you ps output, process 5397 is /usr/mionet/bin/cvm if you disbale mionet, this problem should be solved.
