    It seems that you try to start a 64bit DB2 instance. Is your OS actually running in 64bit and/or do you have a 64bit version of /usr/lib/threads/libc installed?

    I also recommend that you follow the hint in the error message and run "dump -Tv /usr/lib/threads/libc.a".

    this is the output, but i dont know how to interpret this one. we are using 64bit.
