[OpenSIPS-Users] multiple sub interfaces - opensips crashes

[Federico Edorna]

If it helps, we are using pgbouncer <https://www.pgbouncer.org/> to avoid
opening a lot of connections to db. Pgbouncer acts as a db server for
opensips with full workers connections and opens just a few (on demand) to
real db server. It helps a lot when you have backup/standby opensips, not
increasing those db connections.
