GeoServer uses connection pools, so it's normal that they are not closed,
they are supposedly
just given back to the pool.
We need to understand if we are leaking them (not releasing them back to
the pool), or if it's just
that you setup the pool with too many connections, compared to what your
dbms is willing
to support.
If it's the first, you'll see the code fail with an error stating it was
not possible to get a connection
from the pool... that does not seem your case.
If it's the latter, we probably need to understand better your setup, how
many mosaics, your
datastore.properties, and so on.
In general, if you have many dbms based mosaics, you will have a separate
pool for each, which will
quickly exhaust your connections server side, unless you setup a shared
connection pool at the
tomcat level, expose it via jndi, and refer to it that way.
