    This server is making me miserable. Note that it was recently optmized (Thx Chirpy)

    How should this be best managed? Sometimes IOWAIT = 80%!!

    The server load script just sent me this email:

    Your server appears to have a high load. (WHICH IS ACTUALLY QUITE LOW THAN IF MAILMAN WAS ENABLED!)

    The load averages are:
    1 minute: 4.79 (4.79 per CPU)
    5 minutes: 4.01 (4.01 per CPU)
    15 minutes: 4.28 (4.28 per CPU)

    Here is what was just recorded as the current load.

    - The process ID #28381 under the user nobody is using 81.9% CPU and 2.0% Memory with the command 0 /usr/local/ap which has used 0 minutes and 05 seconds of CPU time.

    - The process ID #26694 under the user nobody is using 79.1% CPU and 2.1% Memory with the command 0 /usr/local/ap which has used 0 minutes and 06 seconds of CPU time.

    The top 10 processes are using a total of 273.5% CPU and a total of 39.6% Memory. The process list will follow.

    Hi,

    First let us know what is the process 'ap' and why it is taking too much load on the server,

    Yes, iowait is more than 80% means your disk IO is not responding to the server processes I have also found high swap usage ,

    First I suggest you to upgrade the RAM on this server or provide the output of below mentioend commands:

    # netstat -ntu | awk '{print $5}'| cut -d: -f1 | sort | uniq -c | sort -nr | more

    # ps aux | head -1; ps aux | sort -rn +2 | head -10

    And I suggest you to check the below mentioned URL and then check your server for any diagnosis

    http://forums.linuxwebadmin.info/index.php/topic,51.0.html

    Thanks,
