Christian,

These messages are common on a regular LDM startup, it's the LDM process
contacting the it's own machine (localhost).  Sometimes these messages
result from the LDM timing out the contact process so it exits. I believe
the reason that you didn't see them with the DBFILE action is that pqsurf
started the exit process before the localhost contact process.
