Sounds like each child gets a persistant connection to the database to
reduce overhead during client connections. The number of waiting
connections is equal to the amount of child processes, no?

I've noticed that when I start dbmail-X there always
seem to be a large number of TIME_WAIT connections
reported by netstat. All of these connections are going
to my postgres database.
For example, I only have IMAP running, with the following:
NCHILDREN=5
MAXCHILDREN=20
MINSPARECHILDREN=2
MAXSPARECHILDREN=4
MAXCONNECTS=10000
TIMEOUT=4000
In my netstat output, I have 5 "established" connection to
the database, and then at a minimum of 48 in "time_wait".
That number grows to 55, and then drops back to 48.
When I run IMAP with a trace level of 9, it shows the starting
of the 5 children and then nothing else. (this is a test server
no traffic).
I'm lost as to why this is happening, anyone else see this,
or know why it happens?
TIA
