Dear all,

 

i really have a serious problem with the connection to postgres windows 2008R2 x64 Server,

am using Npgsql .net using VB.NET and trying to make a stress test about the connections ammount, trying to open about 200 sessions from a client Windows7 PC.

Randomly I get an error message in my vb.net from the npgsql saying that “postgresql failed to establish a connection to < pg server name >”  that happen for about 10 percent of the connections randomly, meanwhile on the server itself I found errors like:

 

EOF on Client-Connection

No connection could be made because the target machine actively refused it.

 

When I try to run my program from postgres server locally then all goes fine with no error at all, only from a remote PC or Server, I HAVE STOPED ALL WINDOWS FIREWAL and ANY FIREWAL SOFTWARE on both Server and client, but still facing the problem.

 

Please Help

 

Adel
