Description:

I'm experiencing intermittent yet frequent connect issues with Postgre
8.3.7.971 when accessing remotely. It doesn't seem to matter where I access
it from, but in my experience it's always via remote connection. It works
fine for around 95% of connections, but it immediately disconnects
frequently with the following log entry:

FATAL: could not reattach to shared memory (key=268, addr=02060000): 487

Please help, this is driving me nuts!
