    error thrown by webpshere app server

    --------------------------------

    hi all,
    i got an error thrown in the GC logs for websphere app server 5.1 and am not sure what caused it as the box which the app server sits on is very grunty and has lots of memory and CPU to burn :

    error i got is :

    Exception java.lang.OutOfMemoryError: requested 4 bytes for CMS: Work queue overflow; try -XX:-CMSParallelRemarkEnabled. Out of swap space?


    any suggestions as to what could be wrong ??

    thanks in advance.

    Check heap memory size

    --------------------------------

    I guess GC is running to many cycles so heap size may checked and set to optimum size.

    Check the heap size alloted to that application.
    Even if you have enough physical memory available, the application will only use the memory alloted to it in terms of HEAP SIZE.
    Probably the heap size allotted is not enough for the application. Try increasing this size.
