Topic: Dungog-backup causing 100% load ?

[ask_jeeeves]

Hi,

I am running SME 7.1.3. The last couple of days i have been suffering with my server's CPU running flat out, typicaly 85 - 100% according to emails from sme7admin. I wondered if there is anyway of finding out what it is thats running and using the CPU? I have disabled ClamAV, back-ups etc. I have wondered if it may be Gallery2 which is installed, but i want to try and find out if there is a list i can look at like in Windows.
I'm not sure that this is a bug, more a problem with my server.

Thanks in advance, Rob Miller

Can you do a 'top' command when this is happening?
Email uses clam, and clam seem to be a problem with 7.1.3

[ask_jeeeves]

umm, but it's only just started in the last 48 hours thou???

mine too !  

This is exactly what I'm experiencing:

Mail system and my web (Using Dans with scan active) stop working

Bandaid to clear and rebuild clamav mirrors.dat:

sv d freshclam
rm -f /var/clamav/mirrors.dat
sv u freshclam

Thanks dmay,
What does this do exactly? I have run this but i still have a loaded CPU.
I now find it hard to use server-manager & putty as the server freezes for serveral minutes at a time now!!!!

I have run this but i still have a loaded CPU.

As was mentioned above, run top (or better yet htop) and see what exact processes are at fault.

[ask_jeeeves]

how do i do that?

[christian]

Log in via root in a shell (for example using putty).

at the command line use either the command "top" or "htop"

it will give you a dynamic ordered list  of the processes that are using the most CPU resources.

[ask_jeeeves]

Ah, good that works a treat. Thank You
The problem i am now getting is that my CPU is heavily loaded every few minutes, and when it does the server becomes unresponsive. So when i run the 'top' command in putty its all good and CPU usage is typically under 10%.
But when the CPU becomes loaded, the refresh in putty stops, preventing me from locating the process which is using a high amount of CPU Power.

I have the last hour, received messages from sme7admin exactly every 10 minutes warning me of my high CPU load??

One thing i have noticed although this could be unrelated - i am not sure is:

Code: [Select]

/usr/bin/diff -eN /var/tmp/messages/ /var/log/messages

This seems to be using around 25% Memory

Thanks again in advance,

What are the server's specs?

umm, but it's only just started in the last 48 hours thou???

Did you do/install/update anything 48 hours ago?

Hi, i am running SME 7.1.3
With a Sempron 3000 CPU
512mb RAM
160GB Drive

I havn't done anything i can think of. The last thing i installed was Gallery2 about a month ago.

I have seem a few things about ClamAV? Do you think it's related?

Many thanks,

7.1.3 came out about 3 weeks ago.  Depending on what version you updated from, there were some issues that the upgrade didn't finish properly.

Have you tried the update process again to make sure everything is updated?  Let's make sure you are all current and configured properly.

# yum update
# signal-event post-upgrade
# signale-event reboot

Run the post-upgrade and reboot even if nothing installs.  There have been instances that post-upgrade didn't run properly so do it anyway just in case.

Thanks pfloor,

I have run the above, but i am still suffering with the CPU fully loaded. Any other ideas???

Could it be crond?

That rules out an incomplete update.

Could be anything.  Why do you suspect that, have you done something?
