trouble: Compatibility Mode
identification: This version of the Worder Node is targeted to setup x86_64 machines in "compatibility" mode, i.e. both 32bit and 64bit libraries are provided. The YAIM tool configures the LD_LIBRARY_PATH variable accordingly.
solution: In order to get both 32bit and 64bit libraries, both versions of certain rpms must be installed. On a x86_64 machine yum usually installs the 64bit rpm over the 32bit rpm but for certain rpms this seems not to be the case (for yet unknown reasons). It has been observed that certain binaries in /opt/lcg/bin may be 32bit on the x86_64 Worker Node. However, this should not be a problem as 32bit binaries can be executed on a x86_64 machine.
trouble: dCache client doesn't work in SL5 (Bug 54065)
identification: There is a bug in the dCache client in SL5 that prevents it from working properly.
solution: Use lcg_util as data management client instead.
