I presume that means the client has sent an RST packet, but ... wtf? Why? Is the client on the same machine as the server? If not, is the client running any sort of software firewall? You say the two machines have two different AV products, but you don't mention which ones. What products are they, and what versions of those products? I strongly suspect firewall / antivirus involvement. Can you _uninstall_ your AV/firewall on one of the Pg server machines, reboot it, and re-test? Do not just disable it, completely uninstall it, just for testing purposes. > FATAL: could not reattach to shared memory (key=252, addr=02080000): 487 I've seen discussion of this one before, but never any sort of resolution. http://www.google.com.au/search?hl=en&q=%22could+not+reattach+to+shared +memory%22+%22[hackers]%22 Apparently it arises more often in the presence of antivirus software and the like, but isn't known to be directly caused by it. Maybe somone else can shed some more light on this one. -- Craig Ringer -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
