Hi I'm not sure if this is an XP problem or mysql or JBoss Issue. After 24 hours of runnning JBoss 4.2 on win XP freezes (I cant do netstat or ipconfig). First the connection is reset on the jboss side. Mysql still sees the connection and is just waiting for it to time out. The connection pool tries to get a new connection but mysql rejects the request. I've posted the details in mysql forum. link below -any/all ideas on how to debug this are welcome.
