Hi,

Every since I upgrade to centos 5.3 I see duplicates when running top -c like:

I don't have watchdog installed either.

It seems my load has also gone up and seems like a lot more spam. Getting this in the sanesecurity log:
Apr 09 06:18:17 WARNING - Failed rsync connection to NXDOMAIN reached - SKIPPED MSRBL updates

How would I fix this so there are not duplicates running?

Thanks!

long shot, but have you tried rebooting since your update?

Hi,

I had to reboot because the kernel was updated during the upgrade.

Those are not duplicates, those are threads. Notice that each one has a different pid.

Ok is this normal then?

8 root 10 -5 0 0 0 S 0.0 0.0 0:00.03 [events/0]
9 root 10 -5 0 0 0 S 0.0 0.0 0:00.12 [events/1]

I never saw this before upgrading.

Yep.

Do you have multiple cores or CPUs?

I have a P4 3.2.

Could you tell me if a Xeon dual 3.0 is faster than a P4 3.2?

Its probably hyperthreading on the P4.

A dual Xeon 3Ghz will be a *lot* faster.

However, in the hosting environment, the amount of memory and the speed of the disk is very important.
