Timeout of remote connection to Postgresql

Question

I have two EC2 instances, one of them needs to insert large amounts of data into a Postgresql db that lives on the other one. Incidentally it's Open Street Map data and I am using the osm2pgsql utility to insert the data, not sure if that's relevant, I don't think so.

For smaller inserts everything is fine but for very large inserts something times out after around 15 minutes and the operation fails with:

COPY_END for planet_osm_point failed: SSL SYSCALL error: Connection timed out

Is this timeout enforced by Postgresql, Ubuntu or AWS? Not too sure where to start troubleshooting.

Thanks

Answer 1

Could be caused by renegotiation. Check the log, and maybe tweak ssl_renegotiation_limit = 512MB (the default) setting it to zero will disable negotiation
