    Hello,

    On our server swap memory is not in use. Please check this

    root@server [~]# free -m
    total used free shared buffers cached
    Mem: 2025 1559 465 0 26 526
    -/+ buffers/cache: 1007 1017
    Swap: 6000 0 6000

    The server load is incresing high and not able to trace who is taking the load. Server is not working fine. We rebooted the server but still the same result.

    Is there any solution for this.

    its_joe.

    Go on, have a guess
    What OS and kernel are you running? RedHat have been having a bit of a rough time with their swapfile management in recent kernels going from excessive use to little use in recent times and it could be a symptom of that.

    There may be little that you can do other than stepping outside of the RH kernels and compiling your own. Alternatively, you could tackle the source of the memory issue and look at tuning those applications that are chewing up the available memory.
