Postgres SSL error

Question

I'm trying to run a Drupal migration via SSH and drush (a command line shell), copying data from a postgres database to mysql.

It works fine for a while (~5 mins or so), but then I get the error:

SQLSTATE[HY000]: General error: 7 SSL [error] SYSCALL error: EOF detected

The postgres database connection seems to have gone, and I just get errors:

SQLSTATE[HY000]: General error: 7 no [error] connection to the server

It works fine locally, so I think the problem must be with postgres and running a script over SSH - but googling these errors returns nothing useful. Does anyone know what could be causing this?

Answer 1

Could be a timeout. first inspect the log (maybe change ssl_renegotiation_limit)

BTW: IIRC, the renegotiation does not take place after a fixed amount of time, but after a certain amount of transmitted characters (2GB?)
