hi Yasunori, welcome. 'unclosed sockets' - some client application interacting with your tomcat forgets to close the connection. (like browsers etc) . Or the tomcat doesnt close connection to the database. So, this unclosed connections results in 'unclosed sockets' 'hangin process' - A process which become orphon (very rare!). And joins under 'init' process, that becomes hard to be killed. (I think there might be lots of nice terms to refer to these kind processes) -- Manivannan Palanichamy http://geocities.com/manivannan57
