I'm having a problem where the DRb server seems to be disappearing (crashing?) and I don't know how to track down the cause or work around the problem.
Unfortunately I haven't found a way to reproduce the problem, but it seems to happen fairly often (maybe once a day). Other then that ferret seems to be working well. I can't seem to find any trace of the crash, neither of the ferret_server.out (blank) and ferret_server.log (tail -n 100 after a crash attached below) seem to hold any hints to the problem. So my questions are. 1. Has anyone seen this behavior before, how did you work around it? 2. If no one has seen it, any ideas of where I should look to track it down? 3. Last if I can't fix it how much work would it be to just turn off ferret when the server was down. That would mean indexing and searching wouldn't work, but as it now stands no one can post to my site when the problem occurs.

What if you could open, save and close documents the standard way, but let WriteRoom handle all open documents internally until they are manually closed? Even between sessions? I imagine this could be achieved by using an internal database, or perhaps a folder with \"working\" files under Application Support. This would also serve as a simple versioning system -- you open your file, manipulate it in WriteRoom (perhaps during the course of many sessions) and then save the changes when your ready.\r\nThis would accomplish the same thing as WR 1.0 did, but would be invisible to those who want the familiar old file-system.
