Hello. Can anybody help me with the following? I have server an lot of clients, when they connect(SSL) they pass their pb.Referenceable to server. Server every 2 minutes calls clients' remote method checkpoint(). The problem arises when i disconnect network cable from client side(WinXP) or from server side(linux redhat9.0) - with disconnected cable, server makes remoteRef.callRemote("checkpoint") and i don't get pb.DeadReferenceError exception(no exceptions at all, it prints that it's ok). Only after 15-18 minutes i see on server exceptions that connection was lost. Your help is very, very appreciated. Thanks in advance. P.S. Client side(i use notifyOnDisconnect method) detects losing of connection after 3-5 seconds, but server side... I use twisted 1.0.7rc1 Best regars, Ruslan
