    Hi there,
    I´m having a issue that I don´t find how to fix.

    My server load is fine almost part of the day, with load above 1.
    But suddenly load goes to 30, 50 or even more.

    I try to find wich process is causing the load high, but I don´t find anything different. But the top command, shows me one little thing... the "wa" option is under 95% or more.

    I know the "wa" information means disk usage... i/o, is that right?
    So, there is some process that is making a high usage of i/o, making the server slow but I can´t find this process.

    Do you have any idea about how can I trace this process to fix this issue?

    The spikes happens a few times per day

    Apreceate any help..
    thank you
