I've run into a problem which I'm having a hard time fixing... quite recently I've switched from a jsp reporting scheme to one using datavision. I've field tested it for a few weeks and it was ok. However, quite recently when writing a very complex script it started creating errors on the client side which came up something like:
Could not create Connection: Cannot create PoolableConnectionFactory (
An I/O error occured while reading from backend - Exception: java.net.SocketException:
Connection reset Stack Trace: java.net.SocketException:

At first, I thought maybe it was my script... so I tried running the script from PgAdmin (at this point I haven't done anything with the connection) and the script ran fine... so I tried restarting postmaster.. which didn't work. After which I tried restarting the server, this seemed to have remedied the problem. This was a couple of days ago... now I get this message almost every time and restarting doesn't seem to help, PgAdmin likewise cannot access the database as well. I've been looking around and initially thought it may be just a jdbc problem... however when I took a look at the postmaster logs I got...

I am unsure if my complex scripts had anything to do with this, however, I don't believe this that was the root of the problem. Has anyone encountered similar scenarios?
