does the new centos 4.4. kernel 2.6.9.42 fix load?

[katmai]

does upgrading to this kernel fix the load that we have all seen on our boxes increasing? along with kernel 2.6.9.34 ? any clues>?

 

[dalem]

have not seen high loads ?

kernel 2.6.9.42 came out before centos 4.4 and if you remove it from your skip list it will update

Yes, it should do, unless the high loads are purely excessive load.

The problem with kernel 2.6.9.34 was it often caused a very high iowait which lead to high server load. I don't know if 2.6.9.42 fixes that problem on cento servers, as we had a custom made kernel to fix that iowait problem. Man what a huge difference it made !!

There have been many comments about this already in other threads but I'll put in my two cents. I am running CentOS4.4 and the new kernel you referenced. The new kernel solved all of my load / memory problems. If you are seeing excessive swap file usage, high IOWait times and high cpu usage upgrade your kernel!

Yip, updating the kernel to 2.6.9-42.0.2.ELsmp has solved the problem.

was using 2.6.9-34

I was getting loads of 24 or above and the there were very few files cached and also it was using swap alot.

Thanks for the fix guys

P.S Im using centos 4.4
