Here is the truss output. The client hangs indefinitely and no work is being done other than this error when you truss the process. I use Java 1.5 to run this. We wrote a long-running ftp daemon and this happens after 20-23 hours of continuous running. > Here is the code to pull files from the ftp server. This one lists files that are received after this particular "incal" time (currently it lists but the intention is to implement an incremental download). We initially thought doing periodic noop would keep the client alive by sending dummy commands to the server.
