    After almost 10 hours waiting for the result,  first received a system message to close the application to free up some memory and then I noticed although timer of my program is still running, it is not working any more.

    The message in the "Engine Log" tab is: There may be further errors in the clone logs. 

    I wonder how I can resolve this issue!

    Thanks,

    Shirin

    Hi,

    have you tried with oplrun ?

    do you see important use of memory ?

    How can I find out use of memory? I think it could be displayed in "Profiler" tab. But this tab is clear for me this time and does not display any thing

    I didn`t stop the program... Then it strated "free"ing nodes! 

    and these are the final messages:

    191000 nodes freed
    192000 nodes freed
    193000 nodes freed
    194000 nodes freed
    195000 nodes freed

    Hi

    not constructed because of out-of-memory status.
     

    seems to say that you use a lot of memory

     

    Can you try with less threads ?

     

    cplex.threads=4; within an execute block

    regards
