Vinay, Thanks for the quick response, very much appreciated. I tried the two scripts you pointed to, modifying the client so it produces log messages in an endless loop, and it worked fine. If I left the client running and stopped and started the server, the client would reconnect and messages would start coming through. This is what you observed and what is stated in the documentation. Looking at the SocketHandler Python code shows this would be the behavior as well.
To further complicate my original question, here is more information. The logging server I created uses Twisted (2.5.0) as it's network framework and gets network log messages from the clients using Twisted code. However, once a message is received it is parsed the same way as the example you pointed, in fact that's what I used as a model to build the code in my def dataReceived() method of my logging server Twisted protocol. I don't think there is anything unusual about the network handling in the Twisted framework. The client daemons are also Twisted processes, but in their cases they don't use any Twisted code to send log messages. The log system is entirely based on the Python logging module, and the logging.handlers.SocketHandler system specifically. So the clients should try to reconnect if the server goes down and comes back up. So I'm a little confused what to try next to resolve the problem I'm seeing. By the way, the Python logging system is great, really nice work! Again, thank you for your quick response and help.
