Hi there
I have the occasional "server closed the connection unexpected" errors on a WinXp (about half the time) when I run pljava functions that make an http request to retrieve a web page.
This happens on a localhost.
Any thoughts?
Thank you.
This is the exception I'm getting from jdbc
Exception in thread "main" org.postgresql.util.PSQLException: An I/O error occured while sending to the backend.

pgAdmin error
server closed the connection unexpectedly
This probably means the server terminated abnormally
before or while processing the request.
