    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

    Go on, have a guess
    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
