Configuration.
The LD_LIBRARY_PATH included the directory ../Utility/bin which also included the files
libgcc_s.so -> libgcc_s.so.1
libgcc_s.so.1
libstdc++.so -> libstdc++.so.6
libstdc++.so.6 -> libstdc++.so.6.0.3
libstdc++.so.6.0.3
Once these entries are removed form the LD_LIBRARY_PATH the server processes can be started as expected.
