sockets: resource(20) of type (Unknown)

Hi - I have an problem and I'm not sure how to proceed troubleshooting. I have a socket connection that I'm making to a local stunnel daemon. The connection works and is valid until it seemingly dies and the resource type becomes unknown. at timestamp: 1044900028.6608 my object has this resource: resource(20) of type (stream) at timestamp: 1044900028.6808 it becomes: resource(20) of type (Unknown) I don't think this is a timeout issue, and I can perform all of my functionality via a telnet session without any problems as well. This code used to work great, I have made recent upgrades and changed environments. However the code consistently dies in the exact place, a place where other fsocket reads and writes are successfully been made. Any suggestions would be appreciated. Regards, Jason k Larson
