Dear Mr.Hagander. Thank you for your answer to my report. > The error occurred on the server, not the client if you got that message. > The question is what you did on the server when it happened. I describe the situation when the error occurred a little in detail. The client application connect with the server by "localhost(127.0.0.1)" co= nnection. It output error-code to application log when an error will occurred in libp= q function. When this error happened, I found the error-code means PQconnectDB or PQset= ClientEncoding function in application log. So I suppose that it occurred when this error connect with server. > If it happened connection, then I would look into things like anything yo= u > have configured in shared_preload_libraries for example. I specified following definition in postgresql.conf. shared_preload_libraries =3D '$libdir/plugins/plugin_debugger.dll' Sincerely yours. //Katsuhito Habaguchi > -----Original Message----- > From: Magnus Hagander [mailto:magnus@hagander.net] > Sent: Tuesday, September 04, 2012 4:04 PM > To: fx HABAGUCHI KATSUHITO > Cc: pgsql-bugs@postgresql.org > Subject: Re: [BUGS] BUG #7517: terminated by exception 0xC0000409 >=20 > On Tue, Sep 4, 2012 at 3:00 AM, <katsuhito.habaguchi@fujixerox.co.jp> > wrote: > > The following bug has been logged on the website: > > > > Bug reference: 7517 > > Logged by: Katsuhito Habaguchi > > Email address: katsuhito.habaguchi@fujixerox.co.jp > > PostgreSQL version: 8.3.20 > > Operating system: Windows Server 2008 R2 > > Description: > > > > I'm Katsuhito Habaguchi.
