Celia,

There are 2 things to do, first when the LDM is stopped,  make sure
that all the ldm processes are gone before restarting the LDM.  Also
check that none of the pqact entries are creating a bunch of extra
processes.  You could comment out the exec pqact line in the ldmd.conf
as a test. If you still have the same problem, have your system admin up
the number of processes that the ldm user can obtain.

Robb...
