The table X$KJMSDP has entries for each LMS process that is configured for the instance. The default
number of LMS processes is the number of CPU’s divided by 4, but 2 as a minimum. The LMS processes are
responsible for the delivery of the GCS messages and blocks to the other instances.

As with the LMD process, it is important to check if there are waits for tickets. If this occurs, look at the
corresponding section at the description of the table X$KJMDDP for further explanation.
