    Hi

    I am solving the cutting plane problem and after some iterations i received "Oplrun process is not responding, you must relaunch the Run Configuration"error. Along with is error i got following message in different window,
    "'Oplrun Heart Beat' has encountered a problem. An internal error occurred during: "Oplrun Heart Beat"" If you click on details tab the description is "An internal error occurred during: "Oplrun Heart Beat".
    java.lang.OutOfMemoryError"

    I have MIP problem and I am using OPL with Linux (64 bit, 48Gb RAM)and in script I am ending all the objects with.end() and null specified in https://www.ibm.com/developerworks/forums/thread.jspa?messageID=14478777&#14478777
    I also use workmem to specify memory (to 30 Gb). At the same time i have sufficient ram available while execution.

    Any one can help me in sorting this memory problem?
