Hi Alan, Just a note to say I also see this on my server in the latest 2.0.5. I have tried to catch it, but unfortunately my server is far too busy to leave in gdb. I'll keep trying, but for now, I'm using monit to keep my server running. The error occurs approx. twice a day for me, and takes down the server each time. From what I can tell, the majority of errors happen when a Mac OSX client is attempting to connect, if that helps. If I can grab a gdb trace, i'll post to this list. James
