Hi Dennis,
Please check the dev_sdm & jvm_sdm.out log in work directory, for sdm ports details and error messages
Also check the path /usr/sap/<SID>/DVEBMGS<nn>/SDM/program/log/ for latest log file.
From your previous message it is : /usr/sap/WAP/DVEBMGS00/SDM/program/log/sdmlog20140710.log
Please post the same or try re-starting the java once and check and post the latest generated files
Thanks and Regards,
Nikhil
