We have addressed a handful of issues with the TMCSVC consuming large amounts of the CPU. Most of them are addressed by the latest service pack for LDMS 8.7 (which would be Service Pack 6). There is still one issue we are aware of that is included in a post sp6 patch, but its a fairly rare occurrence. All known issues are addressed in LDMS 8.8 SP3. I would recommend upgrading to the latest Service Pack which can be found here: http://community.landesk.com/support/docs/DOC-1001.
