    I am getting the flashing red icon because my memory is up really high

    what causes the memory to get used up so much? something constantly processing?

    how can I see what is doing it?

    First, see which processes are exhausting your memory. Run the command top and while you are in top hit M to sort processes by memory usage. If that doesn't help, you need to ask your Data Center to check on the memory sticks, there might be a leakage there. Hope this helps!

    Check out these three httpd processes to see what they are. The following command will show only httpd processes.

    ps auxwww | grep httpd

    or

    ps auxwww | grep httpd | less

    The second will pipe the output to less so you can easily search for the IDs of the above processes.


    You can use the Modify Apache Memory Usage Limit function in WHM to limit Apache's memory usage as well.

    If the processes running are normal and functioning properly, you'll need to look at upping the ram in the machine or migrating those accounts to a machine with more ram.

    thanks for the command

    hi,
    thanks for showing a way to catch the RAM Eating process in Apache.

    I've a question.
    when your box is using 2 or 3% CPU and 18% RAM during peak when there are many php based sites having traffic, mostly (wordpress and joomla ones)

    will clicking "Modify Apache Memory Usage Limit " allocate more RAM to apache than the current to let apache use more of RAM for sites which are currently getting served from apache ?

    my current httpd.conf shows.
    #Rlimit added by apachelimits.pl
    #-
    RLimitMEM 291741354
    RLimitCPU 240

    which is approx 278MB

    Will it help by increasing this limit ?

    regards,
    mohit

    Anyways you should do a memory upgrade to the server.

    hi,
    in my case Installed memory is 2GB, and max i saw is 23% memory usage on my box, mostly it stays at 16%-18% but CPU usage sometimes goes to 3 or 4 when few busy php based sites get traffic bunches.

    Any Suggestions ?

    see ya,
    mohit
