Sounds like you're being hit by the Out of Memory (oom) killer in your
kernel maybe? how many connections do you have when this happens?

I think you might need to look at connection pooling. 1024
connections is a LOT of connections. How much memory does your server
have, btw, and what version of pgsql and what os are you running this
on?
