Hello, I am currently using the Dspace 6.3 JSPUI interface, the client side system works normally, I can access all pages and submissions.
However I have been receiving several error emails with the information of "Broken pipe" or "java.net.SocketTimeoutException" and could not identify the root of the problem. Any help is most welcome. Thanks! **************************************************************************** Email received with error info: Exception: java.net.SocketTimeoutException at
