DSpace does suffer from memory leaks - our live installation suffers from them to the extent that the Tomcat server must be restarted daily or it will run out of heap and crash within a day and a half. One place to start looking is any use of the ItemIterator class. Thanks to the pervasive use of database code throughout the application there is an underlying JDBC ResultSet object which, in 1.4.2, is not being freed whenever ItemIterator is used. And ItemIterator is used quite a lot. -- Simon Brown <[EMAIL PROTECTED]> - Cambridge University Computing Service +44 1223 3 34714 - New Museums Site, Pembroke Street, Cambridge CB2 3QH ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
