    OpenJDK 64-Bit Server VM warning: You have loaded library /opt/ibm/ILOG/CPLEX_Studio1251/cplex/bin/x86-64_sles10_4.1/libcplex1251remotejni.so which might have disabled stack guard. The VM will try to fix the stack guard now.
    It's highly recommended that you fix the library with 'execstack -c <libfile>', or link it with '-z noexecstack'.
    building model

    What is the cause for that warning? Is it possible that CPLEX is not running in 64 bit?

    Here are my system characteristics:

    OS architecture=amd64
    OS=Linux
    Java VM version=24.45-b08
    Java runtime name=OpenJDK Runtime Environment
    Java VM name=OpenJDK 64-Bit Server VM
