There was no old server processes running. This has happened twice in two weeks, the system was working for five months. It is enough rebooting the computer in one case, and starting the postgres service by windows's services.msc in the other. Thank's.

The standard question when this happens is - any antivirus or firewall software on the machine? They are known to cause just this type of issues. If so, try uninstalling them (not just disabling, but actually uninstalling is often required) and see if the problem goes away. --=20 Magnus Hagander Self: http://www.hagander.net/ Work: http://www.redpill-linpro.com/

Hi, There is not any antivirus nor firewall software in the machine. There are software made in C# that runs against the DB with the Ngpsql and psqlodbc connectors.=20 Thank's
