Thanks for your answer.
Stoping/starting the server does not solve the problem. It reappears quickly. As a work around I still run my DB on Linux Red Hat with Postgres 8.1, but i would like to move to the new Windows 2008 server. How can I know when a fix will be released ? -----Message d'origine----- De : Bruce Momjian [mailto:br...@momjian.us] Envoyé : mardi 21 avril 2009 16:14 À : grouvi Cc : pgsql-bugs@postgresql.org Objet : Re: [BUGS] BUG #4768: FATAL:could not reattach to shared memory:487 This is a known problem. I think stoping/starting the server will fix it. We hope to find the cause soon. --------------------------------------------------------------------------- grouvi wrote: > > The following bug has been logged online: > > Bug reference: 4768 > Logged by: grouvi > Email address: g...@sylob.com > PostgreSQL version: 8.3.7 > Operating system: Windows 2008 x64 > Description: FATAL:could not reattach to shared memory:487 > Details: > > Symptoms: > My DB update scripts crashes with the following error message > FATAL: could not reattach to shared memory (key=288, addr=02020000): 487 > The problem occurs with both autovacuum turned on or off. > > > Configuration: > -> PostgreSQL 8.3.7 > ->Windows 2008 64 bits. > It is a normal install. > I have no antivirus nor Firewall. > There is the Windows Firewall but the problem still occurs while it is > turned off. > > > > Thanks for help. > > > Here is my full postgresql.conf > > # ----------------------------- > # PostgreSQL configuration file > # ----------------------------- > # > # This file consists of lines of the form: > # > # name = value > # > # (The "=" is optional.)
