Hi, I'm trying to retrieve a file via ftp, and Zope locks up: either just the ftp transfer, or occasionally the whole server. It's printing the following error message: 2000-02-18T10:28:45 ERROR(200) ZServer exception in trigger thunk: (exceptions.AttributeError:'None' object has no attribute '_producers' [/usr/local/zope/2-1-3/ZServer/medusa/select_trigger.py|handle_read|82] [/usr/local/zope/2-1-3/ZServer/FTPResponse.py|apply|145] [/usr/local/zope/2-1-3/ZServer/FTPServer.py|retr_completion|360]) Anybody got a solution? Thanks, Robb
