Thread: BUG #4768: FATAL:could not reattach to shared memory:487
The following bug has been logged online: Bug reference: 4768 Logged by: grouvi Email address: ghr@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.) Whitespace may be used. Comments are introduced with # "#" anywhere on a line. The complete list of parameter names and allowed # values can be found in the PostgreSQL documentation. # # The commented-out settings shown in this file represent the default values. # Re-commenting a setting is NOT sufficient to revert it to the default value; # you need to reload the server. # # This file is read on server startup and when the server receives a SIGHUP # signal.

This is a known problem. I think stoping/starting the server will fix it.

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=A0: Bruce Momjian [mailto:bruce@momjian.us]=20 Envoy=E9=A0: mardi 21 avril 2009 16:14 =C0=A0: grouvi Cc=A0: pgsql-bugs@postgresql.org Objet=A0: Re: [BUGS] BUG #4768: FATAL:could not reattach to shared memory:4= 87 This is a known problem.
