The message guide states
GIM24701W SMP/E COULD NOT OBTAIN LINK-EDIT PARAMETERS FOR LOAD MODULE loadmod FOR SYSMOD sysmod. DEFAULTS WERE USED.
Note: This message is normal when SMP/E accepts elements into the distribution libraries for the first time.
The CTS 5.4 load modules were not part of the base R 10 install. The CTS 5.4 was added 10 months after the base install was released by applying PTFS RO98268, RO98270 and RO98277. Now that the client is accepting all the outstanding GA fixes the CTS 5.4 modules are being added to distribution libraries for the first time. That is way the warning message is being generated.
