Nutch-Dev, What do you use for JobTracker now? sun.net.www.http.KeepAliveCache will keep HTTP 1.1 persisent connections open for reuse. It launches a thread that will close the connection after a timeout. This thread has a strong reference to your classloader (through a ProtectionDomain). The thread will eventually die, but if you are doing rapid redeployment, it could still be a problem. The only known solution is to add "Connection: close" to your HTTP responses.
