That is normal, expected, and even desirable. The in-memory list is a fixed 
size, and is meant to fill up. The list is usually the largest pool in the 
in-memory stand, so it's good that it fills up first.

More generally, the key part of that log message is the log level: "Debug". No 
debug-level message is an error: it is just a debug-level message. If it were 
an operational problem it would have shown up at Notice, Warning, or higher. 
See http://docs.marklogic.com/guide/admin/logfiles for a complete list of log 
levels and instructions for setting the log level. If you have a support
