Re: java.net.SocketException: Connection reset by peer: socket write error

Hello!

Thank you very much for this hint - there is indeed a firewall between this in-house appserver and the DB - and that's
beenbugging me personally for ages, since idle PGAdminII-connects would be closed without notice, too, which causes
longtimeout-waits in PGAdminII and forces me to restart the connection. This might be the cause for this issue, too -
andthe admin of our inhouse network seems to be unable to resolve this firewall-behaviour. I'll try and see if it
changesanything, if I switch off of the connection-persitancy ("Maintain connections across client requests").  

Thanks again for your help!

Kind regards

  Markus
