======Many instances of Postgres.exe are running======
If you are running VPOP3 3.0 or later, and look in the 'Processes' list in Windows TaskManager you will probably see multiple instances of **postgres.exe** running.

This is perfectly normal, and does not indicate a problem. The PostgreSQL database works by having a separate instance of postgres.exe for each connection to the database (as well as a few extra for management and house keeping). This behaviour is documented on the [[http://wiki.postgresql.org/wiki/Running_%26_Installing_PostgreSQL_On_Native_Windows#I.27m_seeing_a_lot_of_postgres.exe_processes_even_though_I_only_started_the_server_once|PostgreSQL wiki]].
