[SR-Users] siptrace module doesn't close db connections

[Daniel-Constantin Mierla]

Hello,

in most of the cases, kamailio keeps the connections open for the entire
duration of running. A connection is shared between modules for the same
kamailio process, so if you have auth_db and siptrace, both will use
same connection. How many kamailio processes (and thus number of db
connections) are there is a matter of children and listen parameters, as
well as couple of extra special processes (timers, rpc servers, ...).

Keeping the connection open is done mainly for performance reasons.

Cheers,
Daniel
